SITRANS WM100 motion sensor operates where other systems are prone to failure. The non-contacting design eliminates the need for lubricating, cleaning and part replacement. Downtime and clean-up expenses associated with conveying equipment failure are reduced by the SITRANS WM100. Failure alarms minimize spillage and prevent extensive damage. The SITRANS WM100 can prevent fires caused by belt slippage at the head pulley and warn against conveyor malfunction. 


The SITRANS WM100 has built-in selectable start delays and 1 Form C relay contact. With an aluminum body, it operates from -40 to +60 °C (-40 to +140 °F). 


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