Motion Failure Alarm Controller
A compact, rugged and reliable controller for motion monitoring — The SITRANS WM300 MFA is a highly sensitive dual setpoint motion sensor system, used with up to 2 MSP and XPP probes. It is capable of hi/lo setpoint as well as differential monitoring with 2 additional probes.
A compact, rugged and reliable controller for motion monitoring.
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.

Application
The SITRANS WM300 MFA detects changes in the motion and speed of rotating, reciprocating or conveying equipment. It warns of equipment malfunction and signals through contacts to shut down machinery in case of a slowdown or failure. Its reliability makes it a cost-effective way to protect valuable process equipment.
The dual setpoint system suits most industrial applications. This versatile unit can be used on tail pulley shafts, driven pulleys, motor shaft sensing, belt or drag conveyors, screw conveyor flights, bucket elevators, fans and pumps.
Multiple machines can be monitored with twin, independent probe inputs as well as an additional 2 inputs for differential speed detection (DSD) within a machine monitoring solution such as a belt conveyor comparing the head to tail pulley speeds. An optional analog output module can convert the WM300 into a non-contacting tachometer (NCT) with 2 mA outputs.
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.
