Applications

For monitoring the speed of any shaft when mated with a magnetic-input tachometer and positioned in alignment with the teeth of a ferrous material gear.

Typically, 60-tooth, 16- pitch gears provide the optimum characteristics for RPM measurement, but other gear types can serve special application needs. They are well suited for industrial machinery as well as test stand and laboratory installations. Series 7143 is available in a plastic tube model, supplied with mounting bracket, or in threaded stainless-steel model. Both include a 10-foot shielded cable with mating connector.

Series 7143 features an extra strength permanent magnet pole-piece and high inductance coil. Gear teeth supply the motion within the magnetic field, so that the sensor/gear combination acts as an AC generator. Voltage output is directly proportional to velocity and closeness of the air gap.
