Dwyer PLS Series Offers

Features

• 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
• The 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
• Designed with the industry standard 1-1/4" male NPT connection and mounting flanges
