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 switch 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 amore
