The new heavy-duty motion-sensing switch Sitrans WM100 of Siemens Industry Automation Division is used to detect the absence or presence of motion on rotating, reciprocating, or conveying equipment.
The new device acts as early warning systems to avoid costly process interruptions and equipment breakdowns. Located outside of the process, Sitrans WM100 accurately detects operating conditions without wear on the sensor. Sitrans WM100 can be mounted up to 100 mm (4”) from the ferrous target. The robust motion sensor provides the contacts to shutdown machinery whenever zero speed is detected. On belt, drag, and screw conveyors, or on bucket elevators, fans and pumps, the zero speed alarm option can warn instantly of equipment malfunctions.
The rugged Sitrans WM100 is impervious to dust, dirt, build-up, and moisture and is particularly suitable for primary industries such as mining, aggregate and cement plants. The non-contacting design of Sitrans WM100 eliminates the need for lubricating, cleaning and part replacement. So the new device reduces downtime and clean-up expenses associated with conveying equipment failures.
