TB1A

5.2 Four wire technique

If the reference torque measuring disc has to be operated with a measuring
amplifier using the four wire technique, then the black wire is connected to
the gray wire and the green wire is connected to the blue wire. The
sensitivity of the transducer changes by approx. 0.022 %. The sensitivity
temperature coefficient variation (TK
cause a sensitivity variation. The influences of temperature on the cable are
not corrected. However, measurement accuracy is adequate for many
measurement requirements, even in the case of the four wire technique.
