Why Choose the Carlo Gavazzi CD34CNFLFNCT5 Capacitive Level Sensor?
The Carlo Gavazzi CD34CNFLFNCT5 is a compact capacitive level sensor with foreground suppression designed for reliable non-contact detection of water-based liquids through non-metallic container walls. Part of the advanced Carlo Gavazzi CD34 capacitive level sensor series, it provides intelligent liquid level monitoring while compensating for foam, residue film and moisture build-up that can affect conventional capacitive sensors.
This sensor is engineered for applications where direct contact with the liquid is not possible or desirable. Its foreground suppression technology allows reliable detection of conductive liquids through plastic or glass walls while ignoring unwanted material build-up, making it ideal for hygienic and demanding industrial environments.
With a 10–30 V DC supply, NPN normally closed output, flush mounting design, PVC pigtail connection and rugged IP69K-rated housing, the CD34CNFLFNCT5 is suitable for food and beverage, packaging, chemical processing and industrial liquid monitoring applications.
