Current Sensor - Autoset-VFD

  • Self-calibrating for proof of flow
  • 0.5-135A range
  • N.O. 30VAC/DC or 120VAC output
  • Optional command relay

Applications

  • Detecting belt loss, coupling shear, and mechanical failure on variable frequency drives

Description

The AutoSet™ VFD line self-calibrates to detect belt loss on motors operated by a variable frequency drive. The C-2350VFD line’s microprocessors automatically set the proper threshold - no
false alarms with varying frequencies. Sensor will detect motor undercurrent conditions such as belt loss, coupling shear, and mechanical failure on fans and pumps while reducing installation
time.

Self calibration for proof of floor on fans and pumps

  • Works without costly 'training' of sensor - our sensors are just plain smarter!
  • No need to open hot starter enclosures - save on labor as well as improve safety
  • Only VFD sensor line capable of functioning on VFDs to 0.5A
  • Sensor is always properly adjusted—no call backs
  • Push-button and LED interface:
    • Slow blink = normal operation
    • Fast blink = alarm
    • Fast learn mode (optional): Press/hold button 1 second, LED makes 2 fast blinks.
    • Go/No mode (optional) : Press/hold button 5 seconds, LED makes 3 fast blinks.

Split-core with optional command relay

  • Easy installation and provides stop/start/status in unitary device—saves component and installation space/cost

Maintenance-free—no call backs

  • Superior to differential pressure sensors
  • Industry leading 7 year warranty
