Series PLS Paddle Level Switch

Series PLS2 Paddle Level Switch

3 Sensitivity Settings, Top or Side Mounting

The Series PLS2 Paddle Level Switch is an electromechanical level switch designed for level monitoring of bulk materials. The rotating measuring vane is driven by a brushless synchronous motor at one revolution per minute and as product builds up, the paddle rotation is impeded and the resulting motor torque activates the output switch and stops the motor. The PLS2 is designed with the industry standard 1-1/4" male NPT connection and unit can be side or top mounted.
