Measuring high current in circuits such as DC power supplies requires shunt resistors. Unfortunately, those resistors affect the circuits performance because of the voltage drop needed to make the measurement in the first place. Plus, shunt resistors generate heat that needs to be managed. Microhm Electronics NSR series of metal-foil resistors contain an embedded Pt100 RTD sensor that you can connect to a temperature-measurement circuit or instrument to monitor the resistors temperature. The drawing below shows the voltage (V...
