An integrated temperature transmitter is a commonly used temperature detection instrument in industrial automation process control. It is suitable for measuring media with strong pulse changes in pressure, pressure shocks, and frequent sudden unloading in production processes. 

It utilizes thermocouples or resistance temperature detectors (RTDs) as temperature sensing elements. The output signal from these sensing elements is sent to the transmitter module, where it is processed by circuits to convert into a current signal or voltage signal linearly related to the temperature, and can also output digital signals such as HART.

These transmitters are nearly applicable across all industries and are typically categorized into integrated temperature transmitters and separate temperature transmitters. They are easy to install, cost-effective, and widely used in industries such as metallurgy, power generation, petroleum, chemical, light industry, machinery, and more.
