  1.  PRODUCTION
  1. Shaft speed switches
  2.  

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 the pulse frequency (shaft RPM) crosses to the alarm side of a trip-point threshold, a corresponding relay de-energizes, indicating the alarm.

  • Shaft speed switches function/ Application?
  • Zero Speed Switch - A switch used to determine if a rotating shaft comes to a complete stop. 
  • Overspeed Detection - Utilizing a Speed Switch to monitor a shaft for speeds that exceed the determined setpoint.
  • Underspeed Detection - Utilizing a Speed Switch to monitor a shaft for speeds that fall below a desired setpoint. 
  • Reverse Speed Detection - The detection of a shaft which not only stops but begins to rotate backwards.
  • Combination sugesstion:

  • Slide Gate & Valve Position Sensors overview

All six Position Feedback Monitors in the SG1000 Series provide independent and accurate feedback of a slide gate's or a valve's position to an external device such as a PLC or optional PM500 Process Meter Display Unit. Models are housed in a rugged, explosion-proof cast aluminum enclosure that is dirt, dust, grease-proof, and water resistant.In the case of a power failure, all SG1000s are designed to retain accurate gate position.

  • Two relay slide gate position sensor overview

The SG1000RA is a stand-alone system for those looking to accurately monitor gate end-point positioning or equipment. With a two-relay output, the SG1000RA can control equipment, lights, horns, or other various facility alarm systems. After a simple set-up, the SG1000RA triggers its relays once the slide gate reaches its fully-open or fully-closed positions. Just like the other SG1000 models, the SG1000RA is housed in an explosion-proof enclosure that is dirt, dust, grease-proof, and water resistant.
