A tachometer is basically a measuring instrument, which is designed in a way that can measure the rotation speed of a rotating object. Traditionally, the device would comprise of a dial and a needle which indicates the current readings and markings, the markings would also tell the safe and dangerous levels. Presently however the digital tachometers have taken over the traditional ones. They show the readings in a digitized format, as against the needle and the dial and hence are much more resourceful.

In this article, we shall discuss the various common types of tachometers which are prevalent in the industry. Each different type of tachometer has different applications. Some are used in the automotive industries and planes, where as others are used in medical instruments and hospitals etc. Take a look at various types of industrial tachometers to understand them better.

Voltage Based Tachometers – as the name suggests, these are the tachometers which require a source of voltage to determine the speed and perform various other tasks. An example of voltage based tachometers would be the DC generator tachometer ...
... and also the drag cup tachometer. They have a very simple way of functioning. The amount of voltage which is being produced will be directly proportional to the speed of the tachometer. Thus, these tachometers are capable of providing both direction and speed to the rotation.

Frequency type tachometers – this frequency type tachometer calculates the amount of pulses produced due to a rotating field tachometer. They require a higher degree of precision and digital circuitry, as opposed to the voltage based tachometer, which are barely simple to use.

Laser Tachometers - Traditionally, a tachometer would require a contact between the instruments and an object which is being measured. However, in various settings, where the physical contact is not feasible, due to various safety reasons or technical reasons, the laser tachometers are used in order to take the measurements from a safer distance. The working of tachometer, though is complex, but is fairly simple to understand. A tight beam of light is pulsed against the rotating object from a distance. The object under the study will have one reflective spot and the tachometer measures the rate at which the light beam is reflected back. Either laser tachometers can form the permanent part of the system or they can be handheld and used especially for a particular case, where it is a bit difficult to strike the connection.

In the automobile industry, these tachometers have a significance of their own. They are used to measure the revolutions per minute of the engine and hence help to determine whether the engine is up to its peak performance or not. Depending up on the nature of the industry that your company belongs to, pick up the most apt tachometer from the given range.

Tachometer,Amp Hour Meter, Humidity Controller are two important devices used in manufacturing industries to check the humidity level which can be crucial to a number of manufacturing process. Therefore it is advised that you purchase quality instruments so that you might not end up on the losing side.
