Mucon Rotalog Paddle Switch

The Mucon Rotalog Paddle Switch High Level Indicator, flange mounted


For specific point indication, the Mucon Rotalog Paddle Switch is second to none.

Thousands are in operation giving this unit a reputation for being reliable, durable and effective.

Three main models are available, in a range of voltage and paddle options to suit any level indication requirements.

The Rotalog rotary paddle switch by Mucon is designed to signal the presence, or absence, of bulk materials such as powders, chemicals, chips, and granules. It is ideal for hoppers, silos, and bunkers as well as for blockage detectors on conveyor chutes. The detection of the material is achieved by a paddle which is rotated inside the container; if material impedes the rotation of the paddle, the control signal changes and after approximately half a second the motor circuit switches off. In this state all active parts are stationary; therefore no wear takes place
