Exton, PA – The L1 Series level sensor provides overflow protection in fluid sensing applications. It can be used as an independent overflow protection device or with other sensors for added security against overflow. The L1 sensor is a non-mechanical device with no moving parts that uses capacitive sensing technology to detect liquid level. It incorporates a patented circuit design that provides immunity to electrical noise. The sensor’s 16mm probe is inserted directly into the fluid and setup and adjusted using its pushbutton ”teach” function without having to remove it from the process. Available in five probe lengths that can be adapted to most applications, the L1 sensor is available in four lengths: 5in., 11 in., 19 in., and 29 in. The device is a dc, PNP unit, programmable either normally open or normally closed with an accuracy of
