Product Overview

LC3015 displacer level gauge is featured by stable accuracy, good linearization, easy installation, field indication, remote output 4~20mA or HART communication and etc. Its operation principle is: A displacer immersed in the measured medium, as liquid level changes, the displacer will move by the buoyancy force thus makes the change of spring length which connecting with displacer and then the spring spurs magnet steel, so that the magnet field close to Hall effect sensor will be changed. This change is proportional to buoyancy force (liquid level). Hall sensor converts the magnet signal into DC mV signal that finally converted to circuit signal via CPU and output two wire 4~20mA DC and digital signals conform to HART communication protocol.
