FAQ:

Q: What is a digital tachometer?

A: The Tachometer is an RPM counter which counts the no. of rotation per minute. There are two types of tachometer one mechanical and another one is digital. Here we are going to design an Arduino based digital tachometer using an IR sensor module to detect object for count rotation of any rotating body.

Q: What is the range of a 6 inch contact tachometer?

A: It has a range of 0.10 – 25000 rpm. This portable contact tachometer has a six inches wheel for measuring the speed of motors, conveyor belts, and other moving and rotational systems. It can measure rotational speed, linear speed, and surface speed.

Q: How does a non-touch tachometer work?

A: In the case of non-touch tachometers, a spot on the disk or rotating body is marked. The frequency of the spot per unit time is measured which gives the speed of the rotating shaft.

Q: How is rpm expressed on a tachometer?

A: Usually it is expressed in revolution per minute or RPM. Earlier tachometers are purely mechanical where the revolution is transferred to the tachometer through mechanical coupling (cable or shaft), the rpm is determined using a gear mechanism and it is displayed on a dial. With the advent of modern electronics, the tachometers have changed a lot.
