Abstract
A force transducer device is described having temperature compensation and including two force transducer units mounted to a fixed support along a common axis by a first mounting member attachable to the fixed support and engaging one end of the two units, and a second mounting member engaging the other end of the units, the device further including force applying means for applying the external force along the common axis of the two units. Also described is an electrical circuit connecting the two force transducer units together such that force-generated signals are added to each other and temperature-generated signals are subtracted from each other, thereby compensating for any temperature variations.
