An RTD, or Resistance #Temperature Detector, is a metal device that changes its resistance as temperature varies. For example, a Pt100 RTD, made of platinum, has a resistance of 100 ohms at 0℃. Despite its direct correlation between resistance and temperature, industries typically don't measure the resistance of an#RTD to determine temperature; instead, they employ alternative methods. | RealPars

19K views · 1K reactions | An #RTD is commonly used to measure temperature by passing a current through it and analyzing the resulting voltage. Its linear resistance-temperature relationship, especially exemplified by the Pt100 RTD, makes it a preferred choice for temperature measurement. This linear relationship allows for straightforward derivation of temperature from resistance, simplifying temperature measurement processes. #temperature_measurement | RealPars | Facebook
