Point Level Control for Free Flowing Material BinMaster’s diaphragm switch is designed for use with freeflowing, dry granular or pelleted material being stored in bins, silos or hoppers. Mounted inside or outside of the bin, the diaphragm switch – also called a pressure switch – can be used for detecting high, intermediate or low levels of material. The device is connected to a light, horn or point level alarm panel and activates an alert when material comes into contact with, or falls away from, the diaphragm switch. For Non-Hazardous and Explosion Proof Applications Made with pride in BinMaster’s 75,000 square foot plant in Lincoln, Nebraska, USA this diaphragm switch features simple, rugged construction at a very affordable cost. Internal or external mounting options are available, with the external mounting option requiring a hole be cut in the bin wall. There are also several options for the diaphragm cover including standard and heavy duty neoprene, neoprene with nylon mesh or heavy duty silicone. The BM45 model is designed for nonhazardous installations, while the BM65 is appropriate for explosion proof applications. Simple, Reliable Operation The diaphragm switch features a simple operating mechanism making it highly reliable and requiring minimal maintenance. It operates by sensing material pressing against a switch as the bin fills. When material comes into contact with the pressure switch, it activates a sensitive microswitch which can be wired to a visual alarm, such as a light or an audible alarm, such as a horn. It can also be wired to stop or start a process when materials reach a desired level. Diaphragm Switch www.binmaster.com
