Variable reluctance speed sensor (VRS) Honeywell Sensing and Control

Honeywell speed sensors using Variable Reluctance sensing technology are simple, rugged devices that do not require an external voltage source for operation. The output signal of a VRS sensor is an ac voltage that varies in amplitude and wave frequency as the speed of the monitored device changes, and is usually expressed in peak to peak voltage (Vp-p). Honeywell offers VRS sensors for general purpose, high output, power output, high resolution, high temperature and hazardous location applications, as well as low-cost molded versions.

Best Used For:
Engine RPM (revolutions per minute) measurement on aircraft, automobiles, boats, buses, trucks and rail vehicles; motor RPM measurement on drills, grinders, lathes and automatic screw machines; process speed measurement on food, textile, paper, woodworking, printing, tobacco and pharmaceutical industry machinery; wheel-slip measurement on autos and locomotives; gear speed measurement.
