Force transducer

摘要

The force measurement unit (1), to register the forces of weight on a seat e.g. a wheelchair, has a double bending beam structure (2) with an upper (3) and a lower (4) beam. The beam structure is in one piece with a force intake (5) and a force outlet (6). The intake has a coupling (7) with a threaded drilling (8) for attachment to the seat. The outlet is coupled (9) with a threaded drilling (10) to another support so that both are on a line parallel and coaxial to the force being measured. Two expansion measurement strips (11,12) are at the double beam structure.
