FAQ: About the prestress level and bolt tightening torque, which one is the “final target” for setting up a typical a bolt-clamped Langevin-type transducer?
Transducers and converters prestress and torque parameters.
The fundamental parameter for transducer preloading is the prestress. The ideal prestress remains the same, however, minor adjustment may be necessary because of stress distribution related to mechanical design. On the other hand, torque changes dramatically with mechanical design and dimensions.
