The Kiepe speed monitors are designed to detect shaft rotation, stoppage or reversal.  They have applications in all industries employing rotating machinery.  High reliability and negligible maintenance requirements make them especially suited to materials handling systems in continuously operating plants.

Compact Construction
Multiple Mounting Arrangements
Aluminum, Cast Iron or Naval Brass Housings
Designed for operation under severe conditions
Multiple mounting arrangements and choice of couplings

Models 

SWE:   Monitoring of under speed, over speed and the stoppage of the shaft.   Selection among the 4 different models is based on the range of set points.   These adjustable set points make it possible to establish absolute acceptable under speed and over speed operation of equipment for safety and equipment protection.  If the RPM exceeds the set point, a relay is energized.  There is also a startup delay from 0.5 to 15 seconds to allow time for the conveyor to get moving on initial startup.   Different models allow ranges of from 1 impulse per revolution to 600 pulses per revolution.  This allows ranges from as small as 1.6 RPM and as large as 600 RPM, depending upon model.  Aluminum Alloy case.  230 VAC standard, other voltages upon request.

SW:   Detects direction of rotation and stoppage.  They have two contacts.  One closes when it is rotating clockwise and the other closes when it is rotating counterclockwise.  Selection among the 5 different models is based on RPM required with each switch providing two different RPM's.  Selecting a falling RPM determines the speed at which the switch will disengage while selecting a rising RPM determines the speed at which the switch will engage.  SW units can be provided with mounting brackets and coupling options.  Different models allow running speeds from 6 to 3,000 RPM.  This allows ranges from as small as 1.6 RPM and as large as 600 RPM, depending upon model.  Aluminum case standard, Cast Iron optional optional.  No external power required.

SWi:   Shaft monitor (zero speed).  Intrinsically Safe, for use underground.
