Precision Temperature Measurement Using Resistance Temperature Detector

Abstract

Temperature is a very important parameter and its measurement is a routine process in industries and laboratories. Many industries and processes, from steel manufacturing to semiconductor fabrication, depend on temperature. Accuracy of the temperature measurement will depend on the sensor selected, signal cables used, and the instruments. Selecting the right temperature sensor usually depends on the temperature range of the process being measured, accuracy desired, and the operating environment encountered. A data acquisition system conditions the analog signal from the RTD sensor, making the analog translation of the temperature usable in the digital domain.
