Shaft
Driven Monitors
 SWE:
The SWE units provide 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 start up delay from 0.5 to 15 seconds to allow time for the
conveyor to get moving on initial start up. SWE units are provided
with mounting brackets. Coupling options available.

These units detect 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

the speed at which the switch will disengage while selecting a rising
RPM determines the speed at which the switch will engage. SW units
are provided with mounting brackets. Coupling options available.
