ABSTRACT:
A load-cell balance having a parallelogram load cell body constituted by a stationary column, movable column and two arms connected between these columns, each arm having thin-walled flexible portions to which adhered are strain gauges. Each strain gauge is coated and sealed by a coating made of a material of butyl rubber group so as to be protected against moisture. The coating permits a free deflection of deflectable parts of the balance, even when the load is small, while maintaining a good moisture proof nature, so that the reliability of the balance is much enhanced.
