R-Series Liquid Level Sensor
The R-Series liquid level sensor features an industry-standard SAE 5-bolt flange mount with fully-integrated electronics. The sensor is manufactured to your custom length requirement (up to 500mm long (for longer requirements please visit the Rxl Liquid Level Sensor page) and offers a fully configurable 0-5V analogue output (typically calibrated 0.25V empty, 4.75V full).
Manufactured from aluminium, the sensor utilises solid-state capacitive technology to accurately detect levels of fuel, oil, bio-fuels, water and other liquids. For aggressive or corrosive liquids the
R-Series Stainless-Steel Liquid Level Sensor is available.
The sensor is factory calibrated in your liquid type (or equivalent), ensuring that the sensor is plug-and-play out of the box. We also provide our free ProbeMON or ProbeVIEW calibration software to allow users to re-calibrate the sensor if required.
