Monitor’s tilt switches can be used in a variety of applications and with many different types of materials. The TC-3 can be used with materials 15-60 lb/ft³ (240-960 kg/m³ ), while the TC-1 can be used with materials >45 lb/ft³ (>720 kg/m³ ).
A tilt switch provides indication by detecting the angular position of the tilt switch enclosure. Typically the unit is suspended above the material to be sensed. Internally, a steel ball centers itself over a switch resulting in switch actuation. As rising material contacts the tilt switch (or the extension actuator) the enclosure begins to tilt. When the enclosure body is tilted at 17°, the steel ball rolls off center, deactivating the switch. As material falls away from the switch enclosure body (or the extension actuator) and the unit becomes upright, the ball returns to its original centered position, once again causing switch actuation. The change in the internal switch status is user accessible for signaling alarms, lights, or interfacing with a PLC.
