Simple, low-cost level detection and alerts for bins

The BM45 standard pressure switch alerts to high or low levels in bins containing non-hazardous, free-flowing dry materials.

Tired of climbing bins to know if they are full? Want to stop overfilling bins?

Get affordable point level control for bins containing free-flowing dry solids with a density >20 lb./cu. ft.

How it works:

When material presses against the diaphragm, it activates a sensitive micro-switch that can be wired to start or stop a process or alert to high or low levels in bins using a horn or alarm.

Diaphragm switch features:

  • For bins and some plugged chute applications
  • Rugged construction and simple design
  • Die-cast aluminum housing
  • Neoprene or silicone diaphragm material
  • Internal or external mount
  • Multiple voltages
