Products » Level Sensors » 4223 Lightweight Level Sensor




The GSlevel 4223 is a lightweight capacitive liquid level sensor available in an almost unlimited combination of length and mounting arrangements, all delivered in short lead times.

The sensor is a form fit and function replacement for the R-Series sensors as well as bringing the flexibility to be adapted to a broad range of mechanical mounting configurations. Standard stock adaptors are available for 1, 2, 3 & 5 bolt mounting as well as metric and imperial male thread designs.

Used across motorsport, industrial and defence industries, the 4223 Lightweight Level Sensor has proven reliability in punishing environments.
