    摘要: A refractometric apparatus and method for monitoring the percentage of water in hydraulic and non-hydraulic fluids employ a temperature sensitive device allowing a user to obtain accurate and correct readings of various measured properties. In particular, the temperature sensitive member comprises a prism-wedge-mirror combination in conjunction with a bimetallic strip. The combination ensures the proper angular displacement of a light beam inside the refractometric apparatus and, therefore, the correct reading of a parameter to be measured.

The light generator is preferably placed parallel to and proximate with the inlet face, thereby allowing for a reduction in the depth of the housing. An alternative to this type of light generator is an optical system for producing an accurate image on a highly tilted optical panel inlet face surface relative to the image path. The optical system comprises an image source, an imaging element for creating an image of the object in an intermediate image plane, an anamorphic element for reducing anormorphic distortion of the image, and a telecentric element for reducing keystone-type distortion of the image.
