Test probe- a device with a measuring scale of a given accuracy for determining the clearance between the rail and the surface of the roadway.
The measuring probe can be found in several areas - radio electronics, milling work and temperature studies. What are such devices?
The gap gauge arguably plays a decisive role in parts manufacturing and other milling and turning operations today. This is because now this is a mass production line of products, and it is not possible to check every detail manually, and visually it is almost impossible. Therefore, it is important that the machines do not produce defects, or do so extremely rarely. Manually adjusting the desired position of turning and milling heads has always been quite a troublesome task, and it was often ignored, which is unforgivable today in the age of high technology. So the probes are now responsible for this.
What is it? In its simplest form, these are plates of a certain thickness, which are verified by the manufacturer. Before fixing parts in the machine or setting a gap in it, this parameter is checked with such plates. Moreover, they are sold in certain sets, where the first and last have extreme dimensions that determine the accuracy class of the set, and the intermediate plates increase in thickness with a certain step in relation to the first. The gap or position of the part is determined by simple application.
Depending on the type and accuracy of the work, the required set is selected. As a rule, the most accurate ones have a plate of 0.02 mm, and the maximum size of the thickest plate varies around 1 cm. Even with such a simple design, these probes have several varieties. The fact is that such plates can be machined in such a way that measurement is possible only in one direction. These are the so-called mono-probes; they are suitable only for milling measurements, where inspection of the machine and the part is somewhat difficult with different sides. But a universal probe, which is capable of measuring parameters on both sides, is suitable for both milling and turning operations.
Such convenient plates still required a lot of time to check the machines, because this was a selection, albeit a simplified one, without the primitive instruments and algebraic calculations that had to be used previously. But still, it took time to select the right size. However, plate probes are becoming a thing of the past if modernization occurs in production. Now there are more technologically advanced tools that will take measurements in a split second, and you will immediately know which way to tighten which screw. This, again, significantly reduces the verification time, which means it allows you to do it more often, without stopping the work of the workshop for a long time, only if repairs or adjustments of the machines are required.
The production process becomes cleaner, and entire batches are rejected less often. After all, before, if a machine was off by a couple of millimeters, it would start making defects, which were not noticed immediately, and since the lines were automatic, a large percentage of defects would result. Today, with new probes, you can check and adjust almost before every shift, which reduces the likelihood of failure to almost zero. So what is this miracle device? This is called 3D probe device, just one touch of its head is enough to understand whether your part or machine is in order or not. If you need to identify a defect in a part, then it is passed over the supposed problem area, and when you need to measure the gap, it is simply applied.
By design, it is a body with an indication and an antenna that comes out of it. At the end of the whisker there is a head, which takes readings. Naturally, by producing such a device, its functions were significantly expanded! But let's agree on the design. Its body is very miniature, which makes it convenient for them to work in even very limited space, and the existing modification Zero Master is absolutely the smallest, but this does not affect the accuracy at all, which, by the way, in such probes reaches 0.001 mm. They usually have several attachments, which differ in the diameter of the ball at the end and the length of the rod.
Most models have an analogue dial, however, there is a model with a digital display, which further increases the reliability of measurements, because even our eyes cannot always accurately take readings from the pointer panel.
The main functions that are now available to probes in this design include both old ones, for example, calibrating the spindle position on machine tools, and new ones. New capabilities include the ability to set zero points and determine the eccentricity of the holes being examined. They can also calculate length and depth, determine the curvature of surfaces, or rather, determine sufficient straightness and evenness. Such devices are quite capable of leveling workpieces or those used in work clamping devices. All this work can be done quickly, without a single algebraic calculation, which had to be done in huge quantities, using micrometers and other devices near the machine. One of the large manufacturers of the new generation of such probes is the company Heidenhain.
Measurements play a very important role in our lives, especially when it comes to other electronics. In order to carry out measurements in this area, there is a huge variety of instruments. The probe can be called an intermediary that stands between the object being measured and the instruments. If you explain in simple language, what such a probe is, it is the most common wiring, which is designed to connect the device with the value that needs to be measured. This is exactly the pencil-shaped tip that is applied to the object.
Such probes fail faster than measuring instruments, to which they connect, so you often have to purchase them additionally. In radio stores there is, of course, a sufficient selection, but often it does not satisfy our needs, and all because, despite the abundance of shapes and sizes of such “electric pencils”, their tip is still quite rough, thick, in general , inconvenient to work with, especially with miniature parts. In this case, many experienced electricians make them themselves, customizing them to their requirements.
In addition to electrical probes, you can find another area in which you need a device with a miniature tip that will quickly measure the desired value. This is the area of temperature surveys. Sometimes there is no time and opportunity to keep a thermometer in the environment whose temperature should be measured; also, thermometers do not always support the temperature range that we may encounter in a series of consecutive measurements. Then a temperature probe comes to the rescue. It's also small and neat in its own way appearance a device in which to obtain a result it is enough to touch its head to the surface under study.
All such probes (both temperature probes and those described above) do not require constant calibration, they are already well configured by the manufacturer, verification is needed extremely rarely, so the accuracy will always be at its best. They are easy to use and can work in wide range temperatures, both negative and positive, and readings are taken in a fraction of a second. This is useful in cases where it is impossible to stay in the measurement area for a long time, or there is no time, for example, refrigerators or, conversely, coolants. Such a device is successfully used in the construction of asphalt-bitumen roads and in other areas.
An electronic meat probe is designed to measure the temperature inside a piece during cooking in the oven.
Based on the thermometer readings, they can determine whether the heat needs to be reduced or added. They also determine the remaining baking time. Using the tool is simple, the main thing is to choose the right accessory suitable for home culinary tasks. There are many options, so it’s worth studying the theory before going to the store.
If you are still wielding a knife and fork, piercing chicken, duck or boiled pork to check readiness, know that you are ruining the dish. A thick point damages the fibers, causing the product to lose its juice.
Checking the readiness of meat and poultry using a probe - old way, which appeared long before the invention of electronic thermometers. Previously, this tool was actively used by professional chefs in cafes, canteens and restaurants. The simplest tools were thin and sharp steel pins with a handle. Long needles were made from hard of stainless steel.
We used the probe simply - we stuck a long needle between the fibers of the meat, so as not to damage the integrity of the piece, to the middle, and then evaluated the result. If signs of a raw product remained on the metal, cooking continued.
Simple needle probes are also used to determine quality raw meat. The device takes samples from the depths of a carcass or piece for bacteriological and microbiological studies.
Modern devices are supplemented with thermometers. Monitoring the heat level is important to properly cook meat and poultry. For various types meat requires different heating temperatures. For large pieces, it is the temperature inside that is important, not the readings of the oven thermometer. For example, beef should be cooked at 65-75 degrees, and pork at 90.
Probes for determining the temperature inside the product are divided according to the type of thermometer into electronic, mechanical and alcohol-based.
Electronic more accurate, compact and convenient. The digital thermometer instantly calculates the temperature in the thickness of the piece, and the display displays it. Models are sold with memory and advanced functions that help determine the cooking time for different dishes. In line electronic probes There are options with a built-in and remote thermometer.
Mechanical with arrow and dial, easy to design and operate. The temperature is displayed on the scale, and some manufacturers describe the types of meat and the degree of frying for the convenience of housewives. Round thermometers are convenient for frying with a glass lid, as they do not take up much space in height.
Alcohol dipstick to measure the temperature of meat works on the same principle as a thermometer for water or air. The cheapest variety. It takes time to get accurate values.
Oven temperature probes can be included with your oven, complementing a standard thermometer. In this case, the accessory is connected to a special connector in the oven, and the temperature is displayed on an external thermometer. The advantage is that you only need to make one puncture. In advanced ovens, oven power control is adjusted automatically based on the temperature probe readings.
There are individual devices wired and wireless. Wireless models are convenient because the cord does not interfere with closing the oven door tightly, and you can control the baking without being in the kitchen. Electronic temperature probes consist of a thermometer with display and a stainless steel probe with a heat-resistant cord. Power usually requires readily available batteries. Compact devices have a built-in thermometer.
How to use a meat probe:
More detailed instructions you need to look for it in the kit with the devices or on the manufacturer’s website. All models are different, so there may be nuances and differences.
Interesting in this series temperature probes with two thermometers– one shows the temperature in the oven, and the second shows the product. This option is convenient for those who have a broken thermometer in the oven or are cooking in the oven.
When choosing a meat temperature probe, start by assessing the quality and strength of the needle, and only then move on to studying the functions and reliability of the thermometer.
The working part of the probe comes in different types:
Stainless steel – best material for the dipstick. Stainless steel is easy to wash and disinfect; it is not afraid of heat and water. The steel should be hard and the tip sharp. A thin working edge is important to ensure that the fibers remain intact and the juice does not leak out during the frying process.
The length of the probe depends on the products. For poultry carcasses, boiled pork, cutlets, steaks and schnitzel, a needle up to 10 cm is sufficient. For larger ones, it is better to buy professional tool at least 15 cm. However, do not forget that the temperature must be measured in the middle of the piece, so focus on half the thickness of the product.
Compact folding meat probes with the ability to measure temperature are convenient for storage, since the sharp part is removed. Suitable for home purposes. Some manufacturers include in the kit protective covers. Silicone covers are comfortable and safe.
Important point - heat resistance of the case. If you plan to leave the dipstick in the oven, then look for metal case With maximum heating up to 300 degrees. Operating range of universal models: from -50 to 300 °C. Also pay attention to whether the display will be visible when you rotate the pan.
Kitchen electronic meat thermometers operate on batteries. Their advantages are the accuracy and speed of temperature determination. On a digital display, values are displayed with an accuracy of fractions of a degree, while on a mechanical and alcohol display, the accuracy depends on vision and viewing angle. Decide what error is acceptable and what is more convenient.
If you like everything modern, then buy a digital device. But if you plan to use it very rarely, choose a mechanical one, otherwise the batteries will be wasted while waiting for cooking. And at the right moment it turns out that the thermometer does not work.
Additional features of electronic thermometers for products:
Based on the type of housing, two groups can be distinguished.
Meat thermometers with removable probe. These devices can be classified as professional. The design consists of a thermometer and a needle connected by a cord. The cord must be heat resistant to withstand hot air in the oven and do not melt from accidental contact with heated surfaces. Advantages - the working part can be removed and washed thoroughly without worrying about the electronics.
Compact models with built-in thermometers. The device in this design is more convenient, takes up less space, easy to care for. Recommended for home use. The housing may be heat-resistant or not - the choice depends on the purpose of the device and its use in the oven.
When comparing different probes with thermometers for meat, poultry and other products in stores, pay attention to temperature Range. Think about what dishes you need the device for. It’s one thing if it’s only meat and fish, and another thing if it’s warm milk or dough.
Some models operate in the range from 0 to 100 °C, others are accurate only in the range of 50-100 °C.
It is convenient if the temperature probe is equipped with a sound indicator. As soon as the temperature is determined accurately, a signal will sound. This will help you determine heat and cooking time more accurately.
For example, consider different variants probes for cooking meat in the oven, in a frying pan and on the grill, as well as models with extended capabilities.
Temperature probe Endever Smart-06 with LED display and backlight, it operates in the temperature range from 0 to 250 °C. Requires four AAA batteries for power supply. The meter cord is heat-resistant and can come into contact with food. There are automatic modes of six degrees of roasting for eight types of meat, a forward and reverse timer, and wireless data transmission. The device can be set up and left in the dish being prepared. It will indicate readiness with a sound signal.
Chinese Digital Thermometer for meat with stainless steel probe TP101 operates in the range from – 50 to +300 °C. This wide coverage makes the compact device almost universal. You can cook anything with it - from cottage cheese and dough to grilled meat and sausages, leaving it in the oven. The length of the working needle is 15 cm. For power, you only need a 1.5V coin cell battery. Attractive price - you can buy a dipstick for as little as 350 rubles in online stores. Suitable for outdoor barbecue.
Temperature probes help not only when cooking meat; they are convenient for measuring the temperature of dough, dough, milk, drinks and other dishes. If you have children or pets, such a device will ensure that baby or special food is comfortable to eat.
Be sure to have at least one probe with a thermometer in the kitchen so that the dishes are always tasty and properly prepared! But don't forget to adjust the heat to achieve the desired result.
As often as I dig for war, I need search probe. With which I can make trenches, trenches and just interesting large signals. In fact, this is a very useful thing, because not all the most interesting things your metal detector can ring.
For example, I often picked up broken Red Army glass flasks from the bottom of a trench, but there is a high probability of finding one intact? And I picked up quite a few plates (not many whole ones). I never thought that you could find so many interesting things with a search probe until I worked hard on it for a couple of trips.
Believe! In our area there is little left of interest that can be found with a metal detector. But a dipstick is more than enough. Because almost no one works with them. Everyone thinks that a metal detector is power. Actually this is not true. Any search party often works with probes as the main tool, and a metal detector as an additional one. After that, draw a conclusion. What better dipstick or a metal detector.
Still having the probe in your hands, you will have to shovel less, much less. Especially if you only dig big signals. Because everyone knows that there is nothing interesting in small signals except orders and medals.
Over time, you will learn to identify roots, stones, iron, glass by sound, and you will even be able to take a soil sample. Just imagine how many functions and probe there are. Even a metal detector doesn't have that much.
From the first time, it will be difficult for you to work with such a device, so you will not understand what is knocking. A stone or something interesting. But after a couple of trips, you will work with them like a professional. I speak for myself.
The probe will be very useful for finding voids in the ground. There are a lot of cellars and basements, covered with earth, which are simply not found. And a metal detector won't pick it up. And the probe will help you in this matter. And as a rule, there are a lot of interesting things in basements. (Antique lamps, irons, samovars, pots) because all this is very much appreciated. For example, I don’t collect this, but I exchange it for coins.
What to make such a probe from? They are usually made from an 8 MM or 5 MM torsion bar. It depends on what kind of soil you will use it in. If the soils are hard, it is better to take 8 MM.
By the way, who doesn’t know what a torsion bar is - it’s a rod in Soviet cars, VAZ, GAZ, etc. Finding it is not a problem at all, in any auto parts store.
A ball from a bearing is welded onto the end of the torsion bar, twice the diameter of your torsion bar. The handle can be made any way, depending on where you will use it. You can just use a sword, or you can use a T-shaped one.
And most importantly, the height of the probe is purely individual. What trenches will you be working with? According to the technology, trenches were dug 1-1.5 m deep, so stick to these dimensions.
Just a minute attention!!! Before you start making or buying a dipstick, I would recommend reading my articles to understand its dangers and specifics. And also, which will be very useful for you to examine rivers, lakes and streams, and maybe even wells.
For example, my probe is like this:
Made from Volga torsion bar. They gave it to me. At the end, the bullet is filled with lead. It really wears out during travel and you have to change it every time before leaving. Therefore, I also want to cut a thread and weld a special bolt, or a ball from a bearing. I'll show you how I can do it later.
There are purchased probes that fold up and have a bunch of replaceable attachments. Which have an orange handle. Which is very convenient. As it happens, you stick a probe into the ground, move 10-15 meters away, and can no longer find it. Because it blends in with the trees.
Therefore, if you make a search probe with your own hands, paint it in a bright color. This will be useful to you, believe me.
By the way, watch the video of the well-known Poryvaev, he says some pretty smart things about probes. And in general, Poryvaev has decent reviews of equipment.
And I would recommend for those who want to start digging, but don’t know which device to choose, to read my article about that. But if you don’t have the funds yet, but want to dig, use a search probe. Believe me, you won’t be left without finds. The main thing is to learn to choose the right places to dig.
One of critical systems engine - lubricant. The resource and quality of operation of the internal combustion engine depends on its condition. The oil filled in the engine provides a thin film, thanks to which scuffing and other defects in rubbing pairs are eliminated. In order for the engine to work for a long time and not cause problems to the owner, it is necessary not only to change the oil on time, but also to periodically check its level. Today, cars are equipped with various sensors that allow you to control the level without leaving the car. But still, the most proven method is to use a dipstick to check the oil level in the engine. Today we will tell you how to use it, as well as how to check the remaining lubricant in the gearbox.
Engine oil plays an important role. It is important not only its pressure on the working engine, but also the residual level.
Yes, if everything is fine with the engine, there will be enough lubricant for the entire 10 thousand service life. But still, no one is immune from leaks. Experts recommend checking the level at least once every 2-3 weeks during daily use. Also pay attention to oil puddles that may form after parking. This may indicate problems with the crankcase seal or leaks in other connections.
note that this operation must be performed with the engine turned off and cooled down. How long do you need to wait? 15 minutes is enough for all the liquid to accumulate in the pan. This is the only way a dipstick for checking the oil level in the engine will show a reliable result. If this operation is done “hotly”, the result will significantly deviate from the actual one.
Another requirement is a flat surface. At the slightest ascents or descents, the dipstick for checking the oil level in the engine will show an inaccurate result. We also need a piece of dry and clean rags.
Where is the oil level dipstick located? This element is usually located in the exhaust manifold area. A typical engine oil level dipstick is yellow or red. It looks like the one shown in the photo below.
It can also be painted black. But in any case, its configuration and shape will remain unchanged. You can easily determine its location in the engine. After the engine has cooled down, we begin checking. We take the element out by the handle and wipe it with a dry cloth. Next, install it back into the hole. After a couple of seconds, the dipstick can be removed again to check the engine oil level. Now let's look at his testimony carefully.
On almost all cars it has two marks - MIN and MAX. There are also intermediate divisions. What is considered a normal level? The readings should be between these two marks (maximum and minimum) or slightly above average. If the lubricant is at the MIN mark, the engine will experience oil starvation. In this case, the level must be urgently restored. You only need to add oil of the same brand and viscosity that was previously used during replacement. After this, check the level again. If it returns to normal, install the oil level dipstick back until it clicks and tighten the filler neck.
As you can see, everything is quite simple. This operation does not take much effort. With timely checks, you can prevent engine damage, thereby extending its life.
It happens that the fluid level in the system drops. It often has to be renewed. Engine manufacturers note that natural oil loss should not exceed one liter per 10 thousand kilometers. If more, you have problems with the motor. What is the reason?
This is usually due to a malfunction. When they lie and scuff on the cylinder walls, the oil directly enters the chamber, where it burns together with fuel mixture. Externally, this factor can be identified by blue smoke from the exhaust pipe. But it may not always manifest itself. If you have a turbocharged engine, lubricant may also go to the compressor. This occurs due to faulty turbine bushings and impeller play. In any case, if the engine “eats” a lot of oil, this is a serious reason for diagnosis.
Nowadays, more and more cars are equipped with automatic transmission. Unlike mechanics, here the transmission of torque is transmitted not by a dry disc, but by ATP fluid. It circulates throughout the transmission under pressure. If the level is insufficient, serious problems with the automatic transmission may occur. Therefore, you need to know how to use the dipstick to check the oil level in an automatic transmission. It is located directly in the box and has a similar handle.
Before taking it out, the transmission must be thoroughly warmed up. The oil should reach an operating temperature of 90 degrees. A trip of 10-12 kilometers as usual is enough for this. After this you need to install the machine on flat surface. Then, with the engine running, move the automatic transmission lever to “Parking” mode. Next, open the hood and take out the dipstick to check the oil level in the box. If you have a car with a transverse engine (front-wheel drive), then this element will be located on the right side of the ICE dipstick. Next, wipe it with a dry cloth and install it back. After 5-10 seconds we take it out.
Just like on the engine, there are two marks here - minimum and maximum. The oil should be at least at the middle level. After checking, install the dipstick in place. If necessary, restore the level to normal.
It is worth noting that different cars have their own markings for the automatic transmission dipstick.
Thus, HOT means “hot” and indicates that the test should be carried out with the engine running. Some manufacturers require the box to be installed during diagnostics. If the dipstick says COLD, the check must be done with the engine turned off.
Experts do not recommend filling oil above the specified level. On an automatic transmission this can lead to increased pressure. Excess oil will be squeezed out through oil seals and other seals. If the dipstick shows a level higher than normal, you should lower it before operating the car. The same goes for the engine. The ideal mark is above average, not reaching the maximum. In this case, the lubrication system will do its job perfectly.
So, we found out and the box. As for manual transmissions, there is a dipstick here too. The check is carried out in the same way “hot” (with the engine turned off). On manual transmissions that do not have such a dipstick, you should use the filler hole as your guide. It is usually unscrewed with a hex wrench. You need to pour oil until it begins to ooze out of this neck.
