Structure and mode of operation
3.1 Measuring element
The measuring element is a rotation−symmetrical body made of hardened
steel (Abb. 3.1).
If there is a loading in an axial direction the measuring element is upset. The
resulting strain is detected by a strain gauge which is connected to a
Wheatstone bridge.
Correction and compensation resistors are placed in the transducer circuit in
order to remove unwanted influences on the zero signal and sensitivity.
Nominal forces 0.2 − 2 MN
