A diaphragmor pressureswitch works by activating a sensitive micro-switch when material reaches the level of the switch in the bin. It sends an alert that can be used to start or stop a process or alert to a high, medium, or low-level in the vessel. Commonly used in grain, feed, seed, or other granular material, BinMaster diaphragm switches are offered for either internal or external mounting and can be wired to a light, horn, alarm, or point-level alarm panel to indicate an alert status. The BM series of diaphragm switches provides simple, low-cost point level control with proven, lasting reliability. Designed for use in bins containing non-hazardous or hazardous, free-flowing dry materials, the BM Switches operate 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 switches are offered in six different models, including standard, heavy-duty neoprene, or heavy-duty silicone diaphragm material, and either internal or external mounting options.
