Transducer for measuring a shaft dynamic behaviour

摘要

A transducer for detecting a shaft dynamic behavior. The transducer comprises an arcuate sensor member supported between an inner member (101) and an outer member. At least one strain gage is attached to a surface of the arcuate sensor member to detect a surface strain caused by a shaft dinamic behavior. The inner member, outer member and arcuate sensor member are substantially coplanar. The inner member comprises a means for attaching the transducer to a mounting surface. The inner member may also comprise a self-aligning feature to optimise a sensor sensitivity in that the inner member is comprising a bore offset (705) from a sensor center (704), the sensor is there by eccentrically rotatable about the sensor center.
