Force transducer for large forces has measurement spring containing several lamellas, with at least one bearer lamella and one measurement lamella connected together by adhesive

摘要

Force transducer has measurement spring (1) in the form of a flexural beam forming a force-extension transducer on which strain gauges are mounted for electrical strain measurement. Measurement spring contains several lamellas, with at least one bearer lamella (4) and at least one measurement lamella (2) connected together by adhesive, welding or other locking arrangements such as bolts and rivets. Measurement lamellas carrying strain gauges are mounted between bearer lamellas.
