Standard Diaphragm Switch

Model: BM45

The BM45 provides simple, low-cost point level control with proven, lasting reliability. Designed for use in bins containing non-hazardous, free-flowing dry 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 an alarm to start or stop a process or alert to high, medium or low levels in bins. The BM45 is offered in six different models including standard, heavy-duty neoprene, or heavy-duty silicone diaphragm material and either internal or external mounting options.
