Non-Contact Tachometer

Non-Contact Tachometer

Photo and laser tachometers are used to measure the speed of rotation, without physical contact. A piece of reflective material is affixed to the rotating component. The photo tachometer emits a beam of infrared light which is directed towards the reflective target. When the light beam strikes the target, it is reflected back to a light sensor housed inside the tachometer. If the component is rotating steadily, the tachometer will count the number of times it receives a reflected signal providing a reading in RPM.

If you need assistance selecting or configuring a tachometer for your speed measurement application please contact us at toll free 1.866.363.6634 or email us at [email protected].
