MEASURING DEVICE

摘要

The invention concerns a measuring device comprising: a sensor (1) with at least one electromechanical transducer (10); at least one electric generator connected to said transducer; and means for determining the electrical impedance at the generator output. Said sensor (1) is run through by a tubular gap (12) inside which a product (14) is capable of circulating, and said electromechanical transducer (10) is located at the periphery of said tubular gap (12), so as to be subjected to a characteristic mechanical load of the product (14) circulating in said gap (12), said impedance representing said load. The inventive device is designed for use in a measuring apparatus for determining the density of the product (14) circulating inside said tubular gap (12).
