Monitors line of tilt bin level 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.
