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.
