The BM45 is a pressure switch that provides simple, low cost point level control with proven, lasting reliability. It is designed for use in bins containing non-hazardous, free-flowing dry materials such as grain, feed, seed or other granular or pelleted materials. The BM45 operates by sensing material pressing against the diaphragm switch. When the swtich is pressed, it activates a sensitive micro-switch that can be wired to a visual (light) or audible (horn or bell) alarm to start or stop a process or alert to high, medium or low levels in bins.

The BM65 offers UL Class II, Groups E,F & G explosion-proof certification and can be used in environments where there is a risk of combustible dust. It provides automatic point level indication of free-flowing dry materials and can be installed to detect high, intermediate and low levels. It provides an audible or visual alert when attached to a horn, siren or light. It features simple, rugged construction and long lasting durability.
