Sensor with supply, and voltage output
In the quarter bridge 4-wire mode the DAQP-STG internally adjusts its excitation so that on the gage the
resistor terminates exactly on the half of the excitation voltage. All wire resistances are compensated.
Why More Wires are Better...
Sensitivity: For sensor wiring typically copper cables are used. For example a 120 Ω full bridge connected
with four 0.14 mm2 cables will have an sensitivity error of 2.1 % due to the 1.27 Ω wire resistance. But with
6-wire technology this can be completely compensated!
