Available models and information on installation

HBM has two different piezoelectric force sensor designs available: The force
washer CFW and the force transducer CFT.

9.2.1

CFT force transducer

The CFT force transducers are calibrated and are delivered with calibration
certificates. As these force transducers are already pre‐stressed internally,
they are suitable for immediate application. Renewed calibration of the
measurement chain is not necessary.
