TEMPERATURKOMPENSERINGSANORDNING VID EN FJEDERVAG

摘要

Spring balance apparatus including a weighing lever supported on a knife edge balance point with one side of the lever acted on by a mass to be weighed against a weighing spring coupled with the other side of the weighing lever, and including an arrangement for the compensation of a measuring error due to temperature change by modifying the ratio of transmission of forces applied to the weighing lever by means of a bimetallic element in which the inventive improvement comprises a knife edge member transferring the forces of the weighing spring to the other side of the weighing lever which knife-edge member has connected rigidly to it an actuating lever coupled to the bimetallic element to alter responsive to temperature changes the orientation of the knife edge member relative to the other side of the weighing lever and thereby modify the ratio of transmission of forces to compensate for measuring error that would otherwise occur due to temperature change.
