Resistance Temperature Detector
The RTD is one of the most accurate temperature sensors. Not only does it provide good accuracy, it also provides excellent stability and repeatability. Most OMEGA standard RTDs comply with DIN-IEC Class B. The accuracy of an OMEGA standard RTDs is shown in the table on the right.
RTDs are also relatively immune to electrical noise and therefore well suited for temperature measurement in industrial environments, especially around motors, generators and other high voltage equipment.
