Tilt Switch

Product Details

The BM-TSM is a mercury-free tilt switch. It has a non-powered, pendulum-type design for fixed mounting on the top of a bin or silo. It is used in powders or solids with a bulk density of at least 15 pounds per cubic foot. It features C/US Class II, Division I Groups E, F, and G, and ATEX Zone 21 hazardous location approvals.

A unique, non-powered design features a patented actuator element assembly that works by sensing angular motion to activate a microswitch. When the sensing probe is tilted to a 15° angle, it activates a contact closure that can be used for direct input to a control system or activate an external alarm such as a horn or light.

The shaft of the BM-TSM tilt switch is custom-made in BinMaster’s Lincoln, Nebraska factory in lengths from one foot up to eight feet in length. Further customize the BM-TSM with either a paddle or sphere mounted at the end of the shaft.

The BM-TSM is for fixed mounting on top of the bin. It installs through a 1-1/4” process connection. For angled roofs, there are 0°, 10°, and 30° mounting plate options available.
