We are offering rotary paddle level limit monitor.
Rotary paddle level monitor has a small low speed, low torque synchronous motor, mounted within a protective enclosure and coupled by a shaft to a paddle, drives the paddle. The paddle rotates freely at a low speed in absence of material. When the material impedes the paddle, the rotation of the paddle is arrested and the motor housing frame moves to another limiting position within the housing and the extension-switching arm (which moves in unison with the motor housing) triggers a dry electrical contact (single pole double throw, i.e. Spdt) to perform a control functions related to material level.
