SITRANS WM100 is a heavy-duty zero-speed alarm switch. This non-contacting unit provides cost-effective equipment protection even in the harshest conditions. This rugged unit is impervious to dust, dirt, build-up and moisture and is ideal for such primary industries as mining, aggregate, and cement. Operating 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. It alarms to minimize spillage, prevent extensive damage or even fire 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
Up to 100 mm (4") gap between SITRANS WM100 and targets
Rugged, low maintenance suitable for tough environments
1 SPDT Form C relay contact
Provides cost-effective protection
Visual indication of target triggered pulse
