ABSTRACT:
A torsion ring transducer has a sensing ring mounted in a ring housing by a first ring web between the housing and the sensing ring and by a second ring web between the sensing ring and a central load application body. The ring housing is secured to a mounting base by an isolation device, for example, a ring cylinder having a defined cylinder wall length in the direction of a central transducer axis and a defined cylinder wall thickness in the radial direction. The ring cylinder prevents mounting effects from reaching the sensing ring.
