     TOUCHSWITCH
     Belt Misalignment Sensor
     APPLICATION

     The Touchswitch is an electro-mechanical limit-switch with no
     moving parts, that detects the misalignment of both pulleys and
     belts in conveyors and bucket elevators.
     The sensor detects the lateral force of the belt or pulley and
     activates a voltage free relay contact. This relay contact can be
     used to send an alarm or shutdown the machine. The sensors
     are usually installed in pairs on opposite sides of the belt /
     pulley.

     FEATURES

       The face of the sensor is made from hardened and annealed
     stainless steel, not soft brass or aluminium, increasing wear
     resistance when the belt contacts it.
       Not affected by dust or material built up; will work when
     completely covered by material.
       An external test knob allows for quick and simple                      TOUCHSWITCH
     sensor/system testing.
       The sensors can be connecting direct to a PLC or for
     increased security to an independant monitoring system such as             U.S. Patent # 6,731,219
