Series PLS2 Paddle Level Switch

Brand: Dwyer Instruments, LLC
Request Information

Free Shipping on Orders Over $366.08 USD

The Series PLS2 Paddle Level Switches 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.
Features
  • Torque adjusting mechanism eliminates the need for different sized paddles
  • 3 sensitivity settings for spring force can be set for light to very sticky materials
  • Brushless synchronous motor assures long term reliability and efficiency
  • Motor shuts ceases operation when paddle stalls
  • Screw cove for easy access with no worries about losing bolts or screws
  • Top or side mountable for added installation flexibility
  • Unaffected by the dielectric constant of the sensed material, making it superior to a capacitance level switch for applications where the dielectric constant is too low, where there is more than one material being used in one vessel, and when material moisture content can change
