If you consider a typical stereo amplifier for a moment ... but by wiring both pots together as a Wheatstone bridge. A meter between the two wipers would detect any current due to a mismatch.

The Wheatstone bridge is a way of measuring resistance ... We solve that by putting an amplifier after the output. There is also non-linearity in the way the thermistor’s resistance relates ...

The internal Wheatstone bridge needs a 10V ac or dc bias supply ... adding that the sensors are not for use in legal metrology. No amplifier nor bridge buffer is included, although Megatron offers a ...

Applications in these laboratory-based measurement techniques include the Wheatstone bridge, current/voltage device characterization, the operational amplifier as an active filter, stress & strain, ...
