Why Choose the Carlo Gavazzi CB32CLN20QVAX Capacitive Proximity Sensor?
The Carlo Gavazzi CB32CLN20QVAX is an ATEX-approved capacitive proximity and level sensor designed for reliable detection of solid, liquid and granulated materials in demanding industrial applications. As part of the Carlo Gavazzi CB32CLN TRIPLESHIELD™ sensor range, it combines adjustable capacitive detection with an integrated OFF-delay and SPDT relay output for flexible process and level-control applications.
The CB32CLN20QVAX provides an adjustable sensing distance of 4–20 mm and uses a non-flush, smooth cylindrical 32 mm diameter housing. Capacitive sensing enables detection of conductive and non-conductive materials, making the sensor particularly suitable for monitoring grain, powders, granulates, liquids and other bulk materials.
Designed for a nominal 24 V AC/DC supply, the CB32CLN20QVAX incorporates an SPDT change-over relay output and an adjustable 1 s to 10 min OFF-delay. Its pre-wired 2 m PVC cable, TRIPLESHIELD™ protection, IP67 enclosure and ATEX Zone 20 approval provide a robust sensing solution for industrial and potentially explosive dusty environments.

Reliable Level Detection for Industrial Applications
Capacitive proximity sensors detect changes in capacitance when a target material enters their sensing field, enabling detection of both conductive and non-conductive substances. This makes the Carlo Gavazzi CB32CLN20QVAX particularly suitable for monitoring levels of grain, powders, granulates and liquids where conventional inductive sensing technology cannot provide the required detection.
The integrated adjustable OFF-delay keeps the relay output active for a configured period after the target is no longer detected, providing useful control functionality for filling, emptying and material-handling processes. Combined with its SPDT relay output, TRIPLESHIELD™ protection and ATEX-approved construction, the CB32CLN20QVAX provides dependable sensing for demanding industrial and agricultural installations.
Typical Applications
- Grain and agricultural material level detection.
- Powder and granulate monitoring in silos and hoppers.
- Liquid level detection and process control.
- Feed, seed and bulk-material handling systems.
- Industrial filling and emptying machinery.
- Conveyor and material-handling equipment.
- ATEX Zone 20 dusty industrial environments.
