Pulse Generators
Split Collar Pulser Wraps
Pulser wraps clamp around a rotating shaft and work with Electro-Sensors shaft speed sensors and are an ideal solution for installations where the end of the shaft is inaccessible. The two halves fasten together around the monitored shaft with recessed Allen head socket screws (provided). Standard and custom models accommodate any shaft diameter, tight spaces, and keyways. • Standard wraps operate to 3,000 rpm (high-speed also available) • Standard wraps available in PVC, aluminum, or stainless steel

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.

Shaft Speed Pulse Generators and Shaft Speed Targets
Shaft Speed Targets are needed to generate a pulse for a Speed Sensor that is monitoring a shaft for RPM (Revolution Per Minute). Electro-Sensors Pulse Generators provide the shaft speed target needed for shaft speed detection with a sensor or switch. We have many options available for all your application needs including customizable split collar pulser wraps.
