Emerson is your one-stop solution for your temperature sensor needs. We offer many calibration options, including Callendar-Van Dusen constants for transmitter-sensor matching to provide the highest level of accuracy. With a variety of sensors available, you’re able to meet a range of industrial application requirements with accuracy, repeatability and stability, while ensuring consistent process control, production efficiency, quality and safety.
Resistance Temperature Detectors (RTDs) are constructed from a resistive metal with leads contained in a protective sheath. Based on the thermal resistivity phenomenon, temperature readings can be inferred from the change in resistance in the RTD, meaning if temperature increases, resistance increases. The resistive metal may be platinum, copper, or nickel with the most common being platinum because of its high accuracy and excellent repeatability.
Thermocouple temperature measurement is based on an electro-magnetic field generated between two dissimilar metal wires at a hot junction compared to a cold junction. The difference in the voltage between these two points allows you to infer a temperature reading. You can measure different temperature ranges based on the metallic composition of the thermocouple.
