Dwyer Instruments” Proximity Division is offering a new capacitive level switch, the CLS2, which uses impulse RF admittance measurement combined with an active guard to provide excellent level measurement and stability while being insensitive to material buildup. This capacitive technology has no moving parts and is designed to auto-calibrate in your application. No need to turn pots, just push the internal calibration button or use the external magnet without even having to open the enclosure. Features of the CLS2 include: universal power supply that works from 12 to 240 VAC/DC without any jumpers or settings; failsafe setting for loss of power; status indication lights of power, sensor, and output; programmable output time delay; and easily removable wiring terminal for wiring of control outside of the enclosure. The switch is a good fit for level indication in silos, receivers, and transporters in pneumatic conveying systems. It is also a good fit for difficult applications, including sludge, slurry, liquids with suspended solids, coating products, and detecting liquid interfaces.
