Strain-gauged load cell and method of compensating the same.

摘要

This invention provides a load cell in which strain gauge resistors, lead portions for connecting them in a bridge and compensating portions for the compensation of the bridge balance, spun or the like are laminated as metal thin films by means of the thin film technique, a protection film is formed over the metal thin films and trimmed by laser beams, and the protection film is made of a pigmented protection film made of synthetic resin for easy and accurate trimming.
