Preloading bolts for piezoelectric force sensors Types 90x1C and 910xC / 9422A

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. 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.
