Dwyer Series CLS2 | Capacitive Level Switch | NEMA 4X DPDT Controller

DWYER SERIES CLS2  | CAPACITIVE LEVEL SWITCH | NEMA 4X DPDT CONTROLLER

The Series CLS2  is a versatile, non-mechanical capacitive level switch designed for reliable detection of liquids, powders, and bulk materials with no moving parts to wear or jam.

  • Automatic Calibration: No need to turn calibration pots, just push the calibration button. The CLS2 even has an external magnet to activate the calibration without having to open the enclosure.
  • Universal Power Supply: One model works from 12 to 240 VAC/DC without any jumpers or settings.
  • Coat Guard: Unit is not affected by sticky, dusty, or clingy materials that coat or build up on the probe preventing false alarms.
  • Failsafe Setting: Output switches can be set for Normally Open or Normally Closed condition on loss of power.

 

 

DWYER SERIES CLS2  | CAPACITIVE LEVEL SWITCH | NEMA 4X DPDT CONTROLLER
The Dwyer Series CLS2 Capacitive Level Switch utilizes state-of-the-art impulse RF admittance measurement combined with an active “coat guard” to ensure accurate sensing even when materials build up on the probe. This technology makes it immune to external RF interference from devices like cell phones or walkie-talkies. It features a universal power supply (12 to 240 VAC/DC) and a DPDT relay output, allowing a single model to handle a vast range of industrial applications. The unit is built with wetted materials of 316 SS and PVDF to ensure chemical compatibility and food-grade compliance.

PRODUCT USES:

  • Wastewater Management: Level monitoring in sumps, reservoirs, and sewage tanks.
  • Food and Beverage: High or low-level sensing in ingredient silos and process tanks.
  • Pharmaceuticals: Reliable level control in sterile and chemical-heavy environments.
  • Pneumatic Conveying: Level indication in receivers, silos, and transporters.
  • Industrial Systems: Monitoring boilers, steam generators, and tanks containing caustics or acids.
  • Interface Detection: Detecting the level between two immiscible liquids, such as oil and water.
