I'm a complete beginner in the design area... but I have this circuit that uses an RTD (a resistor that is relatively linear and proportional with temperature).
I've done a week of reading on bridge networks, op-amp configurations, instrumentation amps, and various other topics, but I don't see a bridge network here!
Can someone help me to understand what the purpose of the configuration of the resistors and how to determine voltage levels between them? I have no idea!
Much thanks and appreciation,
Michael
