Series CLS2 Capacitive Level Switch, Weatherproof, 19" Probe
Powder, Bulk, or Liquids, Auto-Calibration
The CLS2 is a capacitive technology level switch that does not have any moving parts - no jams, no wear, nothing to break, and no maintenance. State of the art sensing technology in the CLS2, using impulse RF admittance measurement combined with an active guard, provides excellent level measurement and stability while being insensitive to material buildup. This technology also provides immunity to external RF sources like walkie-talkies and cell phones as well as minimal interference with radio communication or other electronic systems.
Capacitive level technology can be used for liquids, powders and bulk materials and is great for difficult applications such as slurries, coating products, and liquids and solids. The CLS2 is ideal for level indication in silos, receivers, and transporters in pneumatic conveying systems. The CLS2 can also be used for liquid interface applications to detect the level of two immiscible liquids that have different dielectric constants such as oil and water. Wetted materials of PVDF and 316 SS assure great chemical compatibility and meet food grade requirements.
Features
- 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
- Status Indication: Ultra high brightness external red LED switch status indicator, and internal indicators for power, sensor, and switch status that can be seen externally with window cap option (external LED on weatherproof model only)
- Time Delay: Prevent false alarms from material splashing, agitation, etc
- Removable Terminals: Removable terminal block snaps in and out enabling easy wiring outside of the enclosure.
