The SITRANS WM300 MFA detects changes in the motion and speed of rotating, reciprocating or conveying equipment which is used to indicate a slow down or failure of machinery. Early warnings of a malfunction can prevent damage to valuable process equipment. The dual setpoint system suits most industrial applications. 


A special feature is the adjustable 0 to 60 second time delay, allowing the monitored device to accelerate to normal running speed before monitoring begins. A wide range of probes are available to suit specific needs, including high temperatures and corrosive installations. SITRANS WM300 MFA consistently meets the needs of mining aggregate, cement and other primary and secondary industries.


Key Applications: tail pulleys, motor shaft sensing, screw conveyor flights, bucket elevators, fans, pumps


  • Up to 4" (100 mm) gap between target and probe
  • Over and under speed setpoint detection
  • Setpoint adjustment range 2 to 5000 Hz (120 to 300,000) ppm
  • Adjustable start-up time delay
  • Visual indication of probe operation and relay status
  • General purpose, suitable for majority of applications: rugged probe designs provide unmatched reliability
