The Emotiva PA-1s are ideal for the solid state side, but I'm wondering what tube amps I should look at. The resistance increases as the temperature rises, because of a platinum resistor that has a positive temperature coefficient. Magnum Energy PT-100 > Power Track 100 Amp 12/24/48V MPPT Charge Controller. This instructable shows a full guide of how to use a RTD with Arduino, it uses a two wire PT100 RTD, an Arduino, 3 LM741 operational amplifiers, and resistors. Thermistors : Similar to the RTD, the thermistor is a temperature-sensing device whose resistance changes with temperature. Due to the fact that the Pt100 has less resistance across the sensing element, the resistance from the lead wires will have a higher distorting effect on the overall resistance of the circuit. 1x 220k resistor. Compared to most NTC/PTC thermistors, the PT type of RTD is much most stable and precise (but also more expensive) PT100's have been used for many years. Re: Accurate PT100 Arduino « Reply #13 on: April 20, 2018, 06:20:17 am » If you really want to play with op amps then you want to play with an instrumentation op amp like the INA826.
