Introduction
Most of the current standards for industrial process measurement transmitters are 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, in order to be better used by manufacturers and users, and to systematically provide different types of industrial process measurement transmitters
For a comprehensive test method, GB/T 42567 is proposed to be composed of the following five 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 test reference conditions and a framework for the procedure:
--- 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 the GB/T 42567 series of standards, GB/T 18271 "Working conditions for industrial process measurement and control devices" was adopted:
Many test procedures in "Document", and made necessary improvements:
Reference conditions and procedures for testing transmitters for industrial process measurements
Part 1: General procedures for all types of transmitters
1 Scope
This document establishes a general framework for defining all
Types of reference conditions and procedures for testing transmitters for industrial process measurements: These reference conditions are divided into "standard reference conditions" and "environmental and process
"Process reference conditions": The former is used to determine the accuracy of the measurement, and the latter is used to evaluate the impact of external influences on the measurement:
In this document, an analog transmitter is a process measurement transmitter with an analog current or voltage output, which is a comparison of the techniques and circuits used:
Complexity is irrelevant: All other transmitters with only digital outputs or with mixed analog and digital outputs (e:g: HART) are considered digital
word transmitter:
This document provides general test procedures for transmitters, applicable to all types of industrial process measurement transmitters:
The remainder of this series of standards gives additional specific test procedures for specific types of transmitters (pressure, temperature, level, flow):
Note 1: In industrial process applications, the term "industrial transmitter" or "process transmitter" is often used to indicate a process measurement transmitter:
Note 2: In order to simplify the expression, the abbreviation "transmitter" is used instead of "industrial process measurement transmitter":
Similar devices (such as sensors) with analog outputs are outside the scope of this document:
