Sensors • Speed Sensors

A type of tachometer, a speed sensor detects the rate or rotation of various industrial applications that utilize belt-driven conveyor pulleys. Most speed sensors are suitable in applications ranging from -40 to 230F and are primarily used to measure the speed of a vehicle’s wheel rotation.Types of speed sensors include: rotary speed sensors, bearingless motor speed sensors, bearingless wheelset speed sensors, speed sensors with pulse doubling, speed sensors for non-magnetic target wheels, optical sensors, magnetic sensors, piezo sensors, and doppler radar.
