Numerous production control and related applications
include under speed as with chain, belt, screw, and related conveyors; also
zero-speed sensing for web, belt or coupling breakage, etc. Specific
production uses include startup of motors for mixing units, rotary kilns,
blower fans, mine pumps, sequencing conveyors, etc.
The 3-wire Low Voltage Sensors are ideally suited to
installations with hazardous atmospheres as the 24V DC power level and
non-arcing plastic housing. They can be used in intrinsically safe
installations when applied with appropriate zener barrier protection.
