ABSTRACT:
Temperature, pressure and liquid level parameters are sensed by the variable ratio fiber optic coupler sensor wherein the optical coupling ratio varies in accordance with stress applied to the coupler encapsulant resulting from application of the parameter being sensed. Such use of the coupler sensor is particularly advantageous in fuel tanks, which are subject to spark hazard. Vertical arrays of such sensors are utilized to determine levels of liquids in such fuel tanks. Various sensor configurations are disclosed.
