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.
