Tachometer: Characteristics, Types, Prices, uses …

November 2, 2021

tachometer is a tool that has been created in order to know what is the speed at which an object is circulating through time. Commonly, this element is used in daily life in common circumstances that we usually cannot recognize with the naked eye.

One of the clearest examples of a tachometer that we know is the one found on the dashboard of any vehicle , since it is responsible for informing at what speed it is traveling. However, this element was certainly created after having gone through various formulas and having created laws that help establish the speeds that we know today.

However, it is not just a simple element but a tool that continues to help produce optimal results, and is that it is highly used in laboratories around the world, in order to know the speed at which any element.

What is a tachometer?

As simple as the definition of the tachometer mentioned above may sound, this element has superb specifications and characteristics that help the speeds of the rotating elements and their turns on their own axis, to be established with precision.

Despite the above, it is not as simple as it sounds and requires a lot of information and studies so that it is possible to understand the way in which the speeds are established. However, it can be explained in a simple way with a formula that indicates that the revolutions per minute ( RPM ), being these the units of measurement used by the tachometer, are nothing more than the turns generated by the element that is in motion, For every minute that goes by In this way the tachometer is read and the measurements are established.

On the other hand, the history of the creation of the tachometer tells us that this element does not only specifically measure its speed. This is usually analyzed from its own name, where Tacko , as a prefix, means speed, while Metron , as a suffix, means measure.

Currently, it is highly used to measure motor speeds and any other device that works precisely, so that its quality of useful life and the time that it will be able to withstand it is established. In addition, it also helps to reduce or accelerate such speed, according to the specifications and needs of each situation.

Tachometer Features

Although tachometers are not the only instruments capable of measuring the speed of an object, they have characteristics that make them the best in most cases, among which the following stand out:

  • It is a tool that ensures precision in your results.
  • If what you are looking for is a result per minute, the tachometer is the ideal tool, especially in elements that are in constant movement such as engines.
  • The values ​​are not lost, since the results tend to be memorized within the tachometer software, to later be sent to other devices to be studied.

Purpose of the tachometer

As it is an element that helps to establish the range of revolutions per minute that an object that is rotating on itself continuously is capable of reaching, we are talking about an instrument capable of having variables of any type and external factors that they are not able to modify their results.

Currently, this tool is widely used in circumstances that include motors, turbines and any other type of speed that is on a flat or irregular surface, as long as it is always in motion on its own axis . In addition, it is not only about this but also to establish a safety margin in these same objects, since if there is a fault in an engine, as a main example, this can be noticed by measuring its speed with the tachometer.

And of course, we have to mention its valuable purpose in terms of vehicles of any type , as long as they work with engines, since the tachometer allows us to establish the exact speed of the same.

How does the tachometer work?

The way in which a tachometer is able to work is quite basic and therefore gives accurate results that are not capable of being modified from the device itself. This is due to the fact that it has a magnet that is activated by any rotating element that is nearby to be measured. That is, inside the tachometer there are different components, where the mentioned magnet turns out to be one of the most important, since it is the one that will work in conjunction with another important object: the transmitter.

This transmitter is the one that is responsible for receiving all the signals offered by the magnet and taking them, while during the same period of time, everything works thanks to the electromagnetic field that forms a ring that is rotating since the magnet begins to move.

It is said that its function is based on the set of all the components, since while one of them begins to mobilize, the others also begin their own functions, thus generating the result. These numbers arise thanks to the magnetic field that is given starting from its force, and it is that it is the one that mobilizes the needles that show the results as a reflex action of the movement that they are studying.

Commonly , tachometers have a digital display that gives the results accurately, without the need to extend the reading of the instrument. Finally, although it receives the information in RPM, integers are seen on the screen. This is because the tachometer has a frequency measurement scale that tends to multiply the result by a thousand.

This means that the whole number shown on the screen must be multiplied by a thousand, so that the results are read in RPM.

What is the tachometer used for?

Although we have commonly mentioned where the tachometer is used and what it is for, this information needs to be broken down, since tachometers are used worldwide in various situations , thus being a highly valued tool in the industrial zone. , especially because inside it are running motors and other rotating elements.

However, there are other equally important uses, such as the one given to it in physics laboratories in order to know at what speed a particular element is rotating, or in land, sea and air vehicles, since all These have motors.

Tachometer types

Based on their high impact on daily life and in various situations in the world, tachometers are usually similar but different at the same time, so they are divided into some types, where the main ones are usually the following :

Analog tachometer

This type of tachometer is one that is characterized by operating through magnetic systems that manage to start thanks to the movement of a set of needles, which will be responsible for generating the numerical result.

Digital tachometer

Being a type of tachometer similar to the previous one, it has the same operational method, replacing the needles with a screen that shows the results digitally, with more precision.

Mechanical tachometer

This type of tachometer is one that is characterized by operating from earlier times, under a process that involves magnets and gears. According to history, this type of tachometer is one of the first to be created.

Optical tachometer

On the other hand, there are the optical tachometers, which are those that use a rather peculiar mechanism, since they seek the projection of light at a distance in order to generate speed measurements accurately. They are usually widely used in some cases.

Contact tachometer

This is one of the most accurate tachometers of all, since it has an added piece that needs to be in contact with the rotating object or its surface, so that starting from this movement, it returns the results.

Electric tachometers

This type of tachometer tends to be one of the most common and current today, especially because it only needs a transducer that is inside its structure, which is responsible for showing the results of the movements thanks to the signals emitted. .

Centrifugal tachometer

Finally, there is this type of tachometer, which was quite popular in the days of steam boilers, and it was able to deliver accurate results. Nowadays it is not usually used on a regular basis.

I am a person with great restlessness and curiosity to learn, discover what I do not know, as well as reinvent myself daily, someone who is curious about life and wants to know. I enjoy sharing knowledge.
This is my personal project but I also collaborate in other blogs, it is the case, the most important web on water currently exists in the US, if you are interested you can read my articles here.
