Dust Ignition Proof, Stainless Steel Shaft Speed Sensors with Analog Output

The patented ST420-LT and ST420-DI are 2-wire, loop-powered, 4-20mA analog output shaft speed sensors. They detect passing magnets of a shaft-mounted pulser disc or wrap and output a smooth, continuous 4-20 mA analog signal.
