MEASURING TRANSDUCER FOR MEASUREMENT OF DYNAMIC CHARACTERISTIC OF SHAFT Russian patent published in 2006 - IPC G01L1/22 

Abstract RU 2285903 C2

FIELD: measuring technique.

SUBSTANCE: measuring transducer can be used for measuring characteristics of shaft which has concentric members supporting arc-shaped transducer disposed between them. Measuring transducer 100 has arc-shaped sensor element 102 supported between internal member 101 and external member 103. At least one resistance-strain gauge is attached to surface of arc-shaped sensor element for measuring surface deformation induced by dynamic characteristic of shaft. Internal member, external member and arc-shaped sensor transducer have to be co-planar. Internal member has aids for attaching measuring transducer to mounting surface. Internal member can also have self-aligning aid for optimizing sensor sensitivity.

EFFECT: improved precision of measurement.
