New CD34 Series liquid level capacitive sensors

Capacitive Proximity Sensors for Accurate Level Detection

CARLO GAVAZZI is proud to announce 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.

What’s more, the compact and robust sensor housing with NEMA250 (1, 2, 4, 4x, 5 and 12), IP69K ratings and ECOLAB certification make it very suitable for wash-down applications and harsh environments typically found in the food and beverage industry or applications that are exposed to wind and weather.

The features of the CD34 Series capacitive proximity sensors include:

10 to 30VDC supply voltage
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

The CD34 Series liquid level capacitive proximity sensors are perfect for level applications in markets such as Packaging, Food and Beverage, Agriculture and Water Treatment.
