Abstract
A weighing scale has a housing ( ) that encloses a force transducer ( ). A load-transmitting member ( ) is connected to the force transducer ( ) and passes through an opening to the outside of the housing to transmit the weighing load to the force transducer. An elastic device is interposed between a fixed part that is attached to the housing ( ) and a movable part that is attached to the load-transmitting member ( ). The elastic device is preferably hollow and controllably expandable and contractible by injecting and removing a fluid through a conduit system ( ) with a selectively switchable valve device.
