relatively old and based on analog transmitters: same At the same time, many industrial process measurement transmitters are also developing, and they are very different from analog transmitters: they are usually digital, and in the computing department Part (mainly digital electronic circuits) and measurement part (mainly mechanical structure), both include more functions and newer interfaces: currently saved There are relevant standards for measuring digital transmitters in some processes, but there is still a lack of suitable test methods for some performance aspects: Existing test standards for industrial process measurement transmitters are scattered documents, so identifying and selecting Selecting all transmitter standards for measuring a specific process quantity (pressure, temperature, flow, level, etc:) is difficult, impractical and time consuming: In order to solve the above problems, so as to be better used by manufacturers and users, and to provide systematically for different types of industrial process measurement transmitters For a comprehensive test method, GB/T 42567 is proposed to consist of the following 5 parts: --- Part 1: General procedures for all types of transmitters: The purpose is to provide measurement and control systems for industrial processes and machinery All types of transmitters used provide the reference conditions and procedural framework for the experiments: --- Part 2: Specific procedures for pressure transmitters: Intended for use in measurement and control systems for industrial processes and machinery The pressure transmitter provides specific test reference conditions and procedures: --- Part 3: Specific procedures for temperature transmitters: Intended for use in measurement and control systems for industrial processes and machinery The temperature transmitter provides specific test reference conditions and procedures: --- Part 4: Specific procedures for level transmitters: Intended for use in measurement and control systems for industrial processes and machinery The level transmitter provides specific test reference conditions and procedures: --- Part 5: Specific procedures for flow transmitters: Intended for use in measurement and control systems for industrial processes and machinery The flow transmitter provides specific test reference conditions and procedures: In the process of formulating GB/T 42567 series standards, many test procedures in IEC 61298 were adopted, and necessary Improve: Reference conditions and conditions for testing transmitters for industrial process measurement Procedures Part 2: Specific procedures for pressure transmitters1 ScopeThis document specifies process pressure measurement transmitters (PMT, as hereinafter referred to as pressure transmitter or transmitter) specific test procedures: The pressure transmitter can use the remote seal to lead the process variable to the sensing element of the pressure transmitter: When not available from the pressure transmitter When the remote seal is separated, the entire pressure transmitter needs to be tested: For general test procedures, please refer to GB/T 42567:1-2023, which applies to all types of industrial process measurement transmitters: NOTE: In industrial process applications, the term "industrial transmitter" or "process transmitter" is often also used to indicate a process measurement transmitter:2 Normative referencesThe contents of the following documents constitute the essential provisions of this document through normative references in the text: Among
