These standardized pretensioning elements are used for mounting piezoelectric ring force transducers of Type 9021C and Type 9102C. A set of pretensioning elements consists of a pretensioning bolt (PB, high strength, stainless steel of the mold), a centering sleeve (CS), two insulating washers (IW) and a hexagon nut (HN). These accessories are also separately available on request. It is recommended to preload piezo force sensors with at least 20% of their nominal force to increase the accuracy. In addition, the expected tensile and lateral forces have a decisive influence on the specification of the pretension force. Details can be found in the data sheet and the manual of the corresponding sensor.
