Alignment Sensors and Switches
|
|||||
4B's line of sensors and switches for detecting alignment and motion for bucket elevators, belt and drag chain conveyors or screw conveyors.The Touchswitch is an electro-mechanical limit switch with no moving parts, which detects tracking and misalignment problems on bucket elevators and conveyors. When a belt misaligns or a pulley moves over and contacts the sensor, the built in solid-state electronic circuitry detects the lateral force of the belt or pulley and activates a voltage free relay contact. This relay contact is used to immediately alarm and shutdown the machine.
