Electromagnetically operating weighing device - has inductive transducer with movable element passing between coils driven by HF generator

摘要

The weight sensitive element is connected with a movable metal element of an inductive transducer converting the movement of the weight sensitive element into an electric signal. The movable element moves w.r.t. inductance coils rigidly mounted on the case. One of its windings is connected to a measurement circuit, while the other is connected to a supply source. Inductance coils have shell-typed cores (11, 12) on which the windings (9, 10) are mounted with a clearance (8) between them. The transducer movable element (6) is in the form of a plate (7) inserted into the clearance (8), and an h.f. generator serves as the supply source.
