S2/S9
The sensitivity of the transducer changes when operating in four-wire
connection. The change in the thermal coefficient of sensitivity (TK
C
) is
negligibly small. Changing the cable length changes the sensitivity.
There is no correction for the effects of temperature on the cable.

for transducer S2
If you connect the transducer to an amplifier using four-wire connection, you must
connect the sensor circuit to the appropriate bridge excitation circuit:
