Designed to alert when a chute becomes clogged with material, BinMaster's plugged chute detector features a heavy spring and rugged diaphragm material ideal for use in chutes transporting flowing grain, seed, feed, or other granular or pelleted materials. Available for either internal mounting or external mounting, 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. The plugged chute detector is intended for process temperatures ranging from -30°F to 270°F and material bulk densities from 15 to 90 lb./cu. ft.
