DWYER PLS paddle level switch

The Series PLS Paddle Level Switch uses a 1 rpm synchronous motor to rotate a paddle and sense the presence of dry powder or bulk materials. Movement is impeded when product comes into contact with the paddle and the resulting motor torque activates the output switches and stops the motor. The PLS is designed with the industry standard 1-1/4″ male NPT connection and mounting flanges.

Silos
Hoppers

FEATURES

Magnetic drive that isolates and completely seals the control head from the process and environment preventing material or dust from entering the control head.
Motor shuts-off when paddle stalls increasing motor life, preventing motor burnout, and decreasing power usage.
Slip clutch design enabled by the magnetic drive that prevents damage to motor and drive mechanism from sudden or excessive loading on the paddle.
Status indication light on weatherproof models.
Screw cover on the enclosure for easy access with no worries about losing bolts or screws.
Modular design to allow field installation of any paddle, flanges, shaft extensions, or shaft guards.
Flexible coupling available for protection of the paddle and drive from side loads, surges or impacts. Recommended for top mount applications with shaft extension and applications with large or heavy materials.

OPTIONS
