“Setting The Standard For Supplier Excellence” Tilt Switch Level Monitors Monitor’s line of tilt switches are economical, trouble-free point level controls available for detection of dry bulk materials. The units can be used as high level indicators to eliminate bin overflow or to control levels in open piles. In addition, the tilt switches are useful in determining over or under-load on conveyor belts. The simple yet efficient internal construction (one moving part) provides indication when unit is tilted at a 17˚ angle throughout the complete 360˚ of axial arc. Each tilt switch includes a threaded bore for attaching extension actuators which can increase sensing repeatability and protect the tilt switch from direct contact with coarse material. Monitor offers two different models of tilt switches, each suited to satisfy different application requirements. M No Calibration M Minimal Maintenance M Low Cost, High Level Detection 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.

TC-3 - Monitor’s model TC-3 is a light-duty tilt switch constructed from cast aluminum. It is ideally suited for applications where relatively light weight, moderately sized materials are handled (i.e. 15-60lb/ft 3; 240-960kg/m 3 or particle sizes less than 2 inches; 50mm). Typical application materials include feed, plastic pellets, and pet food. TC-1 - Monitor’s model TC-1 is a heavy-duty, weather-proof tilt switch constructed from cast iron. It is ideally suited for applications where heavy coarse materials are handled (i.e. >45lb/ft 3; >720kg/m 3 or particle sizes exceeding 2 inches;...
