Contact Tachometers are used to measure the rotation speed of a rotating object. With a tachometer, the shaft of the rotating component is coupled to the shaft of the handheld tachometer by friction. Simply stated the tachometer shaft will rotate at the same speed as the component you are measuring.

To measure linear speed such as conveyor belt speed use a contact tachometer with wheel attachment. Place the wheel against the conveyor belt and the wheel will rotate at the same rate. The tachometer will calculate the linear speed on the display based on the rotational rate and fixed diameter of the wheel.
