BM-65-RHPC Diaphragm Switch

SKU
730-0675

Plugged chute detection with 0.020” thick, black neoprene with mesh diaphragm and heavy duty switch spring, internally mounted

Pressure switch detects plugged chutes in hazardous locations

The BM-65-RHPC and BM-65-FHPC are plugged chute detectors specifically designed to alert when a chute becomes clogged with material.

They feature a heavy spring and rugged diaphragm material that makes them ideal for use in chutes transporting flowing grain, seed, feed or other granular or pelleted materials.

They offer UL Class II, Groups E, F & G explosion-proof certification and can be used in hazardous environments where there is a risk of combustible dust.

Use them for high and low-level detection and detecting plugs in chutes.

What makes them rugged:

The diaphragm material is a .020” thick, heavy-duty neoprene reinforced with a nylon mesh which makes it very durable. This is the best diaphragm material to use in extremely abrasive material and high-traffic applications. It has outstanding resistance to abrasion and most chemicals, heat, and oils.

Plus, the diaphragm material is flame resistant, offers excellent color stability, and weather resilience. It is intended for process temperatures ranging from -30°F to 270°F and material bulk densities from 15 to 90 lb./cu. ft.

Internal or external mounting:

The model BM65-FHPC is for internal mounting, while the BM65-RHPC is for internal mounting.

Internal mounting does not require a hole to be cut in the chute, but does require entering the chute for installation.

External mounting offers easy access to the operating mechanism and requires a hole cut in the chute, but does not require entering the chute for installation.
