Abstract
In a sensor assembly, an optical fiber with a sensing region is connected at one end through a fiber guide tube to a detector housing containing a sensing detector. At the other end the fiber is connected through a fiber guide tube to a light source which has a reference detector mounted laterally thereto. The sensing and reference detectors are a matched pair of the same type. The guide tube in the source has a bevelled end which reflects a portion of light from the source to the reference detector.
