Advanced Electronics for Industrial Automation

Resistance thermometers are an innovative form of temperature sensors that monitor thermal energy as a function of electrical resistance. This requires a pure metal element, typically copper (Cu) or platinum (Pt), with a proportional and accurate relationship between electrical resistance and temperature.

Generally, resistance thermometers act much like a standard thermocouple: they acquire thermal energy from a process environment and communicate the signal to a transmitter. This information can be viewed directly in the field with a head-mount display, or it can be accessed downstream using additional interfaces. The primary difference is that resistance thermometers exploit the repeatable resistance against temperature relationship of the metallic elements to measure temperature variations. Copper and platinum exhibit strong linearity when it comes to this relative change in resistance. Resistance thermometers can subsequently be used to measure changes in temperature across a broad range with excellent degrees of accuracy.
