Get hot tips on temperature measurement accuracy
For most temperature applications, getting a high level of accuracy is vital. “A Practical Guide to Improving Temperature Measurement Accuracy”, a white paper from Moore Industries, highlights how plant and site engineers can ensure the most accurate temperature measurement for critical applications, and details steps that can help end users improve the stability of their measurements and reduce calibration costs.
Readers learn how to select the best sensor for a particular application and ways to improve the accuracy of the sensor chosen. The paper details the reasons why 4-wire RTD sensors are almost always the best choice for high-accuracy temperature applications, such as eliminating the errors caused by a copper lead wire. The paper also explains the relationship between classes of sensors (such as Standard and Premium Grade thermocouples and Class A RTDs) and their error rates.
Along with learning how to select sensors, the readers learn how to reduce errors caused by plant noise, using bath calibration to minimise RTD measurement errors and the relationship between remote I/O and temperature accuracy.
