Mounting aid for Load washer

Piezoelectric load washers require pre-stressing. The new CPS sets of pre-stressing elements facilitate easy and permanent pre-stressing. They are made from stainless steel and offer the required hardness as well as the bolt pitches selected to match the typical pre-stressing force.

A set of pre-stressing elements includes a bolt, a washer and a nut. The figure below gives a schematic representation of the setup.
