Overview

Details for PLS-W-S-1-0-0-0-0

PLS-W-S-1-0-0-0-0 Paddle Level Switch Dwyer Instruments' PLS-W-S-1-0-0-0-0 Paddle Level Switch is a reliable and economical solution for liquid level detection in various industrial applications. This SPDT (Single Pole Double Throw) switch offers a simple and effective method to control pumps, valves, and other equipment based on liquid level changes. The PLS-W-S-1-0-0-0-0 switch features a polypropylene float with a built-in magnet and a reed switch enclosed in a NEMA 4X rated enclosure. When the liquid level rises and lifts the float, the magnet activates the reed switch to change the switch state. The switch operates on 120 volts and can be used with liquids with specific gravities as low as 0.6. This paddle-type level switch is ideal for applications where space is limited or where more complex float switches are not practical. Its rugged construction and corrosion-resistant materials ensure durability and longevity in harsh industrial environments. Features and Benefits: * SPDT operation for versatile control of pumps and valves * NEMA 4X rated enclosure for protection against dust and water ingress * Polypropylene float with built-in magnet for reliable operation * Suitable for liquids with specific gravities as low as 0.6 * Economical and easy to install Applications: * Liquid level monitoring in tanks, sumps, and reservoirs * Control of pumps and valves based on liquid level * Detection of high or low liquid levels for alarm or safety purposes * Industrial process control and automation Our HVAC supply store offers competitive prices and fast shipping for the PLS-W-S-1-0-0-0-0 Paddle Level Switch and a wide range of Dwyer Instruments products.

Series PLS Paddle Level Switch

Weatherproof and Explosion Proof Option, Rotary Paddle Level Control, Top or Side Mounting for Dry Bulk Materials

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

Product Applications

  • Mining
  • Food and beverage
  • Silos
  • Hoppers
  • 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.
