Abstract

PURPOSE: To obtain a load cell with the improved creep, hysteresis and the like, by giving a perfect insulation to several areas of the sensitive part composed of the metal material via the electric insulated film and then providing the electric resistance the value of which varies according to the level of the load directly onto the surface of the insulated film.
CONSTITUTION: The electric insulated film such as the metal oxidefilm or the like formed by the metal oxide such as the silicon oxide, aluminum oxide or the like is formed on the surface of several areas at the sensitive part formed with the metal material such as the steel, duralumin or other components. Then the electric resistance such as the Ta or Ni-Cr thin-film resistance of 500W2,000Å or the thick-film resistance of 5W15μm obtained by giving a high-temperature sintering to the metal graze resistance which varies its resistance according to the level of the load is provided directly on the surface of the insulted film. In such way, a load cell can be obtained with no adhesive nor the adhering process required.
