Sense lines MUST be connected to the excitation also when 4-wire connection is used. A potentiometer can
be seen similar to a half bridge sensor with ±500 mV/V sensitivity. Therefore potentiometric sensors can be
measured with bridge ampliers. The advantages of using the DAQP-STG for potentiometric measurements
is by adjusting the offset and range, you can focus on a certain potentiometer position with higher resolution.
The scaling is ±500 mV/V equals ±50 % of potentiometer position.
1) ‘R+’ has to be connected only if shunt calibration is required, otherwise it can be left unconnected.
DAQP-STG Quarter bridge signal connection
3-wire sensor connection (Sense+ is connected to EXC+ at the sensor)
Sense leads (SUB-D: pin 3 and 6 must be connected!
- The 3-wire quarter bridge is only able to compensate symmetrical wire resistance
4-wire sensor connection (Sense+ is connected to EXC+ at the sensor)
