CARLO GAVAZZI (Buffalo Grove, IL) has announced the launch of the new CD34 Series liquid level capacitive sensors. The CD34 Series is designed to detect water-based liquids through non-metallic walls, i.e. plastic or glass. The sensors automatically account for the thickness of plastic or glass walls and compensate for any residual films, moisture or foam accumulation while reliably sensing the presence of the liquid to be detected. The sensor is packed with a universal bracket, which provides great mounting versatility for a variety of surfaces, circular (e.g. sight glass, round containers) or flat. The CD34 works out of the box for most applications, as it’s capable of detecting the media (liquid) with a conductivity of 50mS/cm. For the most demanding applications, the CD34 offers teach-in capabilities, which assists in solving the most challenging level applications. Through the teach-in function, the sensor can be calibrated to overcome highly conductive, viscous liquids or tanks with very thin or thick walls. The features of the CD34 Series capacitive proximity sensors include:
- Supply voltage: 10 to 30VDC.
- NPN or PNP output function.
- N.O. or N.C. switching.
- LED to indicate output and power ON.
- Reverse polarity, short circuit and transient protected.
- 2m cable or pigtail M8 connector.
- IP69K for wash-down applications.
- NEMA 250 (1, 2, 4, 4x, 5 and 12) ratings.
- cULus approved.
- ECOLAB Certified.
