RTD Cable FAQs
What are RTD and PRT Cables?
Resistance Temperature Detectors (RTDs) and Platinum Resistance Detectors (PRTs) offer an alternative measurement technology to thermocouples and are generally used at extreme temperatures. RTDs are used because of their simpler operation, increased stability and sensitivity although they have an increased response time. PRTs measure temperature by determining the electrical resistance of a piece of pure platinum wire.
