Supporting -40 to +185°F range that suits diverse industrial environments, Mini-Rotary features polycarbonate NEMA1 housing and can be used as low- or high-level alert for dry solids with bulk density of at least 2 lb/ft³ to 30+ lb/ft³. This point level sensor, employing slow-speed motor to rotate paddle (4-vane or bayonet-style polycarbonate), uses light- or horn-based alert to notify operator of full bin. No calibration is required, and adjustable sensitivity prevents false alarms.
