Device for measuring the mechanical load exerted by a fluid using an electromechanical transducer

摘要

A measuring device comprising: a sensor (1) with at least one electromechanical transducer (10); at least one electrical generator connected to said transducer; and means for measuring the electrical input impedance of the transducer. Said sensor (1) has an empty space (12) passing therethrough within which a substance (14) can flow, and said transducer (10) is situated at the periphery of said empty space (12) in such a manner as to be subjected to a mechanical load characteristic of the substance (14) flowing in said space (12), the measured electrical impedance being a function of said load. The device is suitable for use in a measuring apparatus seeking to determine the density of the substance (14) flowing inside said tubular space (12).
