Transducer

Abstract

A transducer for a mass flow meter, in which the mass flow meter is arranged inside an outer tube, which serves as a pressure receiving part of the mass flow meter. The mass flow meter has a tubular receptacle. At least one flexible plate is capable of vibrating in a torsional manner 5, said flexible plate being provided with a magnetic or magnetizable material. An electrically conductive material is embedded in the tubular receptacle or in the outer tube. The electrically conductive material provides a main current path for the transducer, where current in the main current path induces at least one torque in the flexible plate via the magnetic or magnetisable material. The vibration 10 of the flexible plate induces an electric current in the main current path via the magnetic or magnetizable material, and the transducer acts as a pick-up of the mass flow meter. 215
