Preloading set for piezoelectric force sensors of Types 9021C and 9102C / 9422A21

Standardized pretensioning elements Type 9422A21 for the installation of piezoelectric force transducers of Types 9021 and 9102. These preloading elements consist of an optimized socket head cap pretensioning screw and a centering sleeve. Further accessories, such as electrically insulating washers or force distributing rings, are available separately. The pretensioning screw is used to preload a ring force transducer for optimized force application in the recommended measuring range. When installed correctly, the piezoelectric force sensor provides precise results with high repeat accuracy. In practice, the sensors are mechanically preloaded during installation.
