A potentiometer can be seen similar to a half bridge sensor with ±500 mV/V sensitivity. Therefore potentio-

metric sensors can be measured with bridge ampliers.

The advantages of using bridge ampliers for potentiometric measurements: only one multifunctional mod-

ule with high bandwidth and a programmable offset (by adjusting the offset and range, you can focus on a

certain potentiometer position with higher resolution).

Module conguration

DAQP-BRIDGE-A: Excitation: 0.5 V

Range: 500 mV/V

The following table shows how the mV/V ranges are calculated. The ranges depend on the gain and the

excitation voltage (note that commas indicate decimal points in this table):

⇒ Always change the excitation voltage before changing the input range, otherwise you will not get the required

500 mV/V range.
