Siemens Industry Automation Division has developed a new heavy duty motion sensing switch named Sitrans WM100, to identify the lack of, or existence of motion, on conveying, reciprocating or rotating machinery. It gives out premature warning signals, to foil expensive process interludes and also breakdown of machines.
There is no wear and tear on the sensor, as it is present outside the process, and can precisely define operating conditions. It can be fixed at a distance of100mm (4’) from the ferrous object. The minute the sensor detects zero speed in a machine, it provides information to shut down or stop the machine’s operation issuing warnings or alerts immediately about defective equipments, when it is fitted on belt, screw and drag type conveyors, or even on fans and pumps and bucket elevators.
The Sitrans WM100 is very sturdy, and is not influenced by water, build ups and dust, and hence appropriate for primary industries such as aggregate and cement plants, and mining.
Maintenance expenses are low, as this equipment having a non-contact concept, does not need lubrication or parts substitution or cleaning.
