Thermocouples

Difference between RTD and Thermocouples

Difference between resistence temperature detector and thermocopuples are listed below, Temperature range: First, consider the difference in temperature ranges. Noble Metal Thermocouples can reach 3,100 F, while standard RTDs have a limit of 600 F and extended range RTDs have a limit of 1,100 F. Cost: A plain stem thermocouple is 2 to 3 times…

Resistance Temperature Detector (RTD)

An RTD (resistance temperature detector) is a temperature sensor that operates on the measurement principle that a material’s electrical resistance changes with temperature. The relationship between an RTD’s resistance and the surrounding temperature is highly predictable, allowing for accurate and consistent temperature measurement. By supplying an RTD with a constant current and measuring the resulting…
