This part of IEC62828 establishes specific procedures for testing temperature transmitters used in measuring and control systems for industrial process and for machinery control systems. When the process measurement transmitter features the temperature transmitter separated from the sensing element (RTD, TC, etc.), the standard applies only to the temperature transmitter without the sensing element. In case of device where the sensing element is fully integrated with the temperature transmitter, the standard applies to the complete device. For general test procedures, reference is made to IEC62828‑1 , which is applicable to all types of industrial and process measurement transmitters (PMT). NOTE In the industrial and process applications, to indicate the process measurement transmitters, it is common also to use the terms “industrial transmitters”, or “process transmitters”. The sensing element itself (e.g., RTD, TC, etc.) as well as radiation thermometers are excluded from the scope of this document.
