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 17º angle throughout the complete 360º 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.

Principle of Operation

N/A 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.

Applications

N/A 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 ).

Typical Applications include, but are not limited to:

  • Feed
  • Wood
  • Regrind
  • Resin
  • Silica Sand
  • Calcium Dust
  • Limestone
  • Rocks
  • Rubber
  • Pre-mix
  • Pellets
  • Metals
  • Clays
  • Malt

Features

N/A

  • Passive switch for activating loads up to 250 VAC
  • Cast iron or cast aluminum construction
  • Easy installation
  • Adjustable measurement height
  • Ball-float and paddle-type actuators available

Available Configurations

N/A 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/ft³ ; 240-960kg/m³ or particle sizes less than 2in; 50mm). Typical application materials include feed, plastic pellets and pet food.

Warranty

N/A Monitor Technologies warrants each tilt switch it manufactures to be free from defects in material and workmanship under normal use and service within two (2) years from the date of purchase. The purchaser must give notify Monitor of any defects within the warranty period, return the product intact, and prepay transportation charges. The obligation of Monitor Technologies LLC under this warranty is limited to repair or replacement at its factory. This warranty does not apply to any product which is repaired or altered outside of Monitor Technologies' factory, or which has been subject to misuse, negligence, accident, incorrect wiring by others, or improper installation.
