paddle level switch

series pls paddle level switch

weatherproof and explosion proof option, rotary paddle level control, top or side mounting for dry bulk materials

incorporated in the design of the pls is a magnetic drive that is time proven by decades of use in our mark series valve position indicator product line. A 1 rpm synchronous motor rotates the paddle, utilizing a magnetic drive. As product builds up, the paddle is impeded from moving and the resulting motor torque activates the output switches and stops the motor. A spring mechanism reactivates the motor and returns the switches to normal state when the product no longer impedes the paddle rotation.

standard construction is weatherproof with explosion-proof optional, and the unit can be side or top mounted. The pls is designed with the industry standard 1-1/4" male npt connection and mounting flanges.
