The Series PLS paddle switch from Mobrey may be used as either a high or low level limit switch for dry and solids products and is easily mounted through the wall of the vessel such that the paddle protrudes inside the vessel.

An electric motor drives the paddle which rotates freely in the absence of dry material. When the paddle is impeded by the presence of material, the motor rotates within the housing to actuate a microswitch and signal and alarm. As soon as the paddle is stopped from rotating, power to the motor is cut, extending the motor life. Once the material level falls, the motor is returned to its normal position and the paddle begins to rotate.

Series PLS paddle switches from Mobrey can be used with granular, pelletised and powdered dry products and may be used in high level applications with materials over 160kg/m³ and low or intermediate applications with materials over 80kg/m³.
