Carlo Gavazzi Capacitive proximity sensors for level detection
CD34 series liquid-level capacitive sensors are designed to detect water-based liquids through nonmetallic walls, i.e., plastic or glass. The sensors account for the thickness of plastic or glass walls automatically and compensate for any residual films, moisture or foam accumulation while sensing the presence of the liquid to be detected. The sensor is packed with a universal bracket, which provides mounting versatility for a variety of surfaces, circular (e.g., sight glass, round containers) or flat. The sensors work out of the box for most applications and can detect the media (liquids) with a conductivity of 50 mS/cm.
