DYNAMOMETRIC PROBE FOR REAL-TIME STATIC AND DYNAMIC MEASUREMENT OF VARIOUS PHYSICOCHEMICAL, BIOCHEMICAL OR BIOLOGICAL PARAMETERS OF A LIQUID MEDIUM

摘要

A particularly sensitive dynamometric probe for the detection of variations of molecular structures in a liquid medium and for the static and dynamic measure, in real time, of physical, chemical, biochemical and biological parameters of the same medium. An arm (4) integral with a torsion wire (1) carries at one of its ends an interchangeable vane (10) and a sealing lamella (12). The arm (4) under the driving effect of an electromagnetic device (6, 7, 9) oscillates around the torsion wire (1). The vane (10) is immersed into the medium to be studied (22), which slows down the movement of said vane. An optoelectronic sensor (13 to 15), comprising the sealing lamella (12), measures the angular shift of the arm (4) and emits an electric signal, in analog or digital form. Application: industries and laboratories processing more or less viscous liquid mediums as in the chemical industry, petrochemicals, the pharmaceutical industry, the agri-food industry, various research and medical analysis laboratories or others.
