 The
Zero Speed Switch (ZSS) detects the absence or presence of motion of
rotating, reciprocating or conveying equipment. This non-contacting unit
provides cost effective equipment protection even in the harshest
conditions. Typical applications include tail pulley shafts, driven
pulleys, motor shaft sensing, and screw conveyor flights.
This
rugged unit is impervious to dust, dirt, build-up and moisture, and is
ideal for such primary industries as mining, aggregate and cement plants.
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 ZSS. It alarms to minimize spillage, prevent extensive
damage and even fire caused by belt slippage at the head pulley, and warn
against conveyor malfunction.
The
ZSS has built-in selectable start delays, and one form ‘C’ relay
contact. With a phenolic body, it operates from -40 to 60°C (-40 to 140°F).
