Dwyer Instruments Series PLS2 electromechanical level switch

Click2Contact

The Series PLS2 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. As product builds up, the paddle rotation is impeded and the resulting motor torque activates the output switch and stops the motor.

A spring mechanism reactivates the motor and returns the switch to normal state when the material no longer impedes the paddle rotation. A torque adjusting mechanism eliminates the need for different-sized paddles. The PLS2 is designed with the industry standard 1¼″ male NPT connection and unit can be side or top mounted.

The Series PLS2 also features three sensitivity settings and a screw cover for easy access without the risk of losing bolts or screws.
