The BINMASTER® BM65 Hazardous Location Diaphragm Switch 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. 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, BINMASTER® offers the choice of a standard neoprene, a heavy-duty neoprene, or a heavy-duty silicone diaphragm.

BINMASTER®'s Diaphragm Switch is designed for use with free-flowing, dry granular or pelleted material being stored in bins, silos, or hoppers. Mounted inside or outside of the bin, the Diaphragm Switch can be used for detecting high, intermediate, or low levels of material. 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 micro switch 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.

Materials of Constrution:
  • Neoprene: A synthetic rubber, Neoprene has a variety of properties that make it quite useful, including being abrasion-resistant, chemical-resistant, waterproof, stretchable, and buoyant.

  • Silicone Rubber: Offers the best long-term resistance to environmental extremes. The chemical, electrical, and mechanical properties of silicones remain virtually unchanged at temperature from -160°F to 500°F

  • Neoprene w/ Nylon Mesh: Outstanding resistance to most chemicals, heat, and oils. Further, it is flame-resistant, offers excellent color stability, weather resilience and extremely high abrasion resistance. Low moisture absorption and good dielectric qualities are amont its other features.
