The BinMaster plugged chute detector is a pressure switch specifically designed to alert when a chute becomes clogged with material. It features a heavy spring and rugged diaphragm material that makes it ideal for use in chutes transporting flowing grain, seed, feed or other granular or pelleted materials. It offers UL Class II, Groups E, F & G explosion-proof certification and can be used in hazardous environments where there is a risk of combustible dust. When a chute becomes plugged, it provides an audible or visual alert when attached to a horn, siren, light or alarm panel.
