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 a process or alert to high, medium or low levels in bins.
The BM45 series is offered in six different models. The variations include standard, heavy-duty neoprene or heavy-duty silicone diaphragm material and either internal or external mounting options. The basic, yet reliable
operating mechanism is very rugged and requires minimal maintenance. It can be used in conjunction with EDM's point level alarm panel which is a console used to alert the user to bin level conditions for four to 24 level
indicator stations. It helps saves time by allowing the user to monitor high, medium and low levels of mutliple bins from a single console.
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.
The BM65 offers both internal and external mounting options - with the external mount offering simple installation and easy access to the operating mechanism. To make it adaptable to a variety of materials, EDM offers
the choice of a standard neoprene diaphragm, a heavy-duty neorene diaphragm or a heavy-duty silicon diapragm. The BM65 can be used in conjunction with the point level alarm panel, which provides a centralized alert station
for four to 24 point level indicators.
