Let's discuss #RTD circuit maintenance and troubleshooting. RTDs, like any sensor in industrial settings, can face issues due to corrosion, moisture, or poor connections, resulting in abnormal temperature readings. To test the RTD, use an ohmmeter to measure its resistance, ideally around 110-115 ohms. Using a process calibrator to simulate the RTD can help pinpoint any issues. If the expected temperature displays on the HMI, the problem likely lies with the RTD. | RealPars

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
