Abstract
We present a prototype optical-fiber liquid-level sensor for measuring the static and dynamic level of liquid nitrogen in large cryogenic hydraulic systems. This version of sensor is intended for use for various tests of the cryogenic hydraulic systems at their design stage. The sensor employs a total of 140 highly sensitive optical-fiber point detectors of liquid in a form of vertical linear array. The liquid level measurement range is of 1.6 m, a vertical resolution is up to 5 mm. The optical detectors of liquid are multiplexed by means of matrix-type optical fiber network, which operates under robust level-tracking algorithm. A sensor of this type can be used for measuring the level of other cryogenic fluids.
