Why Choose the Carlo Gavazzi CD34CNFLFNCP2 Capacitive Level Sensor?
The Carlo Gavazzi CD34CNFLFNCP2 is a compact and highly reliable capacitive level sensor with foreground suppression designed for non-contact detection of water-based and other conductive liquids through non-metallic container walls. As part of the Carlo Gavazzi CD34 capacitive sensor series, it is specifically developed for demanding level-detection applications where hygienic installation, reliable switching and resistance to harsh wash-down environments are important.
This sensor can detect liquids through plastic or glass walls, allowing it to be mounted externally without direct contact with the process medium. Foreground suppression and teach-in functionality help the sensor adapt to different container materials and wall thicknesses, while its compact rectangular construction makes it suitable for restricted installation spaces. Integrated protection against reverse polarity, short circuits and electrical transients further supports dependable industrial operation.
With a 10–30 V DC supply, NPN normally closed (N.C.) output and maximum output current of 100 mA, the CD34CNFLFNCP2 integrates easily with PLCs and industrial control equipment. Its 8 × 16 × 34 mm plastic housing, 2 m PVC cable and IP65, IP66, IP67, IP68 and IP69K protection ratings make it particularly well suited to machinery, processing and wash-down applications.

Reliable Non-Contact Liquid Level Detection
Capacitive level sensors detect changes in capacitance caused by the presence of liquid behind a non-metallic container wall. This enables the Carlo Gavazzi CD34CNFLFNCP2 to monitor liquid levels without penetrating the vessel or making direct contact with the process medium, helping simplify installation while reducing potential contamination and leakage points.
The CD34 series is designed to detect water-based liquids including water, milk, syrup and other conductive fluids through suitable plastic or glass walls. Its teach-in functionality allows the sensor to adapt to more challenging installations, while the compact housing and high ingress-protection ratings make it particularly effective for processing machinery and applications exposed to frequent cleaning or wash-down procedures.
Typical Applications
- Water and water-based liquid level detection.
- Food and beverage processing machinery.
- Milk, syrup and beverage level monitoring.
- Plastic and glass tanks or containers.
- Filling and dispensing machinery.
- Packaging and production equipment.
- Industrial process and liquid handling systems.
- Wash-down machinery and hygienic processing environments.
