Why Choose the Carlo Gavazzi CB32CLN20QVAX10M Capacitive Level Sensor?

The Carlo Gavazzi CB32CLN20QVAX10M is a Ø32 non-flush capacitive proximity and level sensor designed for reliable detection of conductive and non-conductive materials in industrial process applications. Part of Carlo Gavazzi's TRIPLESHIELD™ ATEX capacitive sensor range, it combines an adjustable 4–20 mm sensing distance, SPDT relay output and integrated OFF-delay functionality in a robust PBT housing.

The capacitive sensing principle enables the CB32CLN20QVAX10M to detect liquids, powders, granulates, plastics and other materials without physical contact. Its sensitivity can be adjusted across the 4–20 mm range, making it particularly useful for level detection and presence monitoring where the target characteristics or installation conditions vary.

Designed for a nominal 24 V AC/DC supply, the sensor provides an SPDT change-over relay rated up to 2 A at 240 V AC. An adjustable 1 s to 10 min OFF-delay helps prevent unnecessary switching caused by brief changes in the detected material, while the 10 m PVC cable, IP67 protection and ATEX approval support demanding industrial installations.

Adjustable Capacitive Level Detection with OFF-Delay Control

Capacitive sensors detect changes in capacitance caused by the presence of a target material, allowing them to sense both conductive and non-conductive media. The CB32CLN20QVAX10M is particularly suited to level and material detection, with its adjustable 4–20 mm sensing distance allowing sensitivity to be matched to the target and installation conditions.

The integrated OFF-delay provides an important control advantage in level-monitoring applications. Adjustable from 1 s to 10 min, the delay allows the relay to remain in its switched state for a defined period after the detection condition changes. Combined with its SPDT relay output, TRIPLESHIELD™ technology, ATEX approval and long 10 m cable, the sensor provides a flexible solution for industrial process and material-handling systems.

Typical Applications

• Liquid level detection and monitoring.
• Powder and granular material level sensing.
• Hopper, silo and vessel level control.
• Plastic and non-metallic material detection.
• Industrial filling and emptying systems.
• Packaging and process machinery.
• Material presence and absence monitoring.
• Appropriately classified ATEX industrial applications.
