a94-20 – level sensor,capacitive
Carlo Gavazzi A94-20 is a compact capacitive liquid level sensor with an approximately 3 mm nominal sensing distance, thermoplastic polyester housing and 5 m cable for water and liquid-level monitoring applications.
Why Choose the Carlo Gavazzi A94-20 Capacitive Level Sensor?
The Carlo Gavazzi A94-20 is a compact capacitive liquid level sensor designed for reliable level detection in swimming pools and other suitable liquid-monitoring applications. The sensor uses a capacitive sensing principle, allowing liquid presence to be detected without the exposed conductive electrodes used by conventional conductive level probes.
Part of the Carlo Gavazzi A94 level sensor range, the A94-20 features a durable thermoplastic polyester housing and a compact cylindrical construction measuring approximately Ø22 × 51 mm. Its permanently connected 5 m cable provides useful installation flexibility where the sensor must be positioned remotely from the associated control equipment.
The A94-20 provides a nominal sensing distance of approximately 3 mm and is intended for connection to compatible external amplifier or level-control electronics. With an operating temperature range of -25 to +70 °C and robust construction suitable for liquid-level applications, it provides a practical sensing solution for automatic water-level monitoring and control.

Reliable Capacitive Liquid Level Detection
Capacitive level sensors detect changes in electrical capacitance caused by the presence or absence of the target material near the sensing surface. In liquid-level applications, this allows the sensor to determine when water or another suitable medium reaches the required sensing position without relying on mechanically moving floats.
The Carlo Gavazzi A94-20 combines this capacitive operating principle with a compact polyester sensor body and long connection cable. When integrated with compatible level-control electronics, it can form part of an automatic system for monitoring water levels and controlling pumps, valves or associated equipment.
