Shaft Speed Switches
-
A speed switch senses rotating shaft speed, comparing it to one or more settable over/under/zero speed alarm trip-points. A shaft speed sensor detects magnets embedded in a shaft-mounted pulser wrap/disc. As the shaft rotates, the passing magnets are detected across an air-gap as pulses with frequency proportional to shaft RPM. When a conveyor belt or bucket elevator begins to slip the pulse frequency (shaft RPM) crosses to the alarm side of a trip-point threshold, a corresponding relay de-energizes, providing shutdown or alarm.

Shaft Speed Sensors
-
Electro-Sensors offers many shaft speed sensors for virtually any environment. Our Hall-Effect and Magnetoresistive Sensors sense magnetic targets and work with our magnetic pulsers (Discs, Wraps, and Wheels). Our proximity sensors sense ferrous metal targets, including bolt-heads, screws, gearteeth and keyslots. Our speed sensors monitor shaft speed of equipment and output data as PNP, NPN, or 4-20 mA signals. The sensor data can be used by facilities to monitor machinery and safeguard equipment. Monitoring shaft speed is a fundamental aspect of hazard monitoring and should be utilized by any facility with rotating shafts.
