Abstract
A load cell wherein strain gauges are produced by a thin film process on a pattern forming surface of a strain-inducible element in such a manner that the resistances of the strain gauges are varied in accordance with deformations caused in thin portions of the strain-inducible element, and adjustable resistors are deposited by the thin film process for an electric circuit assembly including a differential amplifier, a potential divider, a signal amplifier and a zero-point setter. And each of the resistors is adjusted by trimming simultaneously with trimming adjustment of the strain gauges.
