BM-25 Diaphragm Switch: Point Level Detector for Bins and Chutes

The BM-25 diaphragm switch is a high or low-level alertpressure switch forbins containing non-hazardous, free-flowing dry materials.

Need an Inexpensive Level Switch? Want to Know When Bins are Full or Empty?

The BM-25 diaphragm switchescan help reduce overfilling and stop important grains and fertilizer from being wasted. With the help of the BM-25 diaphragm switch, users canrecognize whether chutes or conveyors are clogged without making a mess.

How it Works:

When material meets the level of the switch in the bin, a sensitive microswitch is activated, which is how a diaphragm (or pressure) switch works. It provides a high-, medium-or low-level warning that may be used to start or stop a procedure.

What to Use the BM-25 for:

Material density from 20 lb./cu. ft

Monitoring levels of dry, free flowing materials

Installation in ordinary locations

Detect plugging of chutes or conveyors

Eliminate overflow or maintain a certain level of material

Levels of grain, feed,or fertilizer

Point level detection in bins and silos

The BM-25 is ideal for agriculture cooperatives, farmers, or any business storing dry bulk solids.
