SUMMARY
The Gill liquid level sensor is a lightweight, solid-state capacitive liquid level sensor available in an almost unlimited combination of length and mounting arrangements, all delivered in short lead times. It is compatible with a wide range of liquids and is able to operate in high temperatures.
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.
FLEXIBLE MOUNTING OPTIONS
For real product flexibility, you have the ability to design your own custom configurations to suit any flat gasket seal configuration, limitless thread adaptions to both Male and Female threads.
To order, simply tell us your probe length requirements and you Fuel/Oil/Water or Coolant type for calibration and we produce a fully sealed and ready to use sensor. You can then choose one of our off-the-shelf adaptors or request the CAD data to produce a customised adaptor of your own.
