By activating an alert when the device tilts at least 15 degrees, the versatile, cost-effective BM-T tilt switch level indicator can be used to detect high levels of large, heavy materials in bins, tanks and silos. Alternatively, it can be used to detect plugs or clogs in chutes during process operations or as a load sensor when positioned over open piles or conveyor belts. An optional paddle extension can be used to increase the sensitivity of the tilt switch.
