GB/T 20730.1-2006 Industrial-process control systems—Instruments with analogue inputs and two-or multi-state outputs—Part 1:Methods of evaluating performance

Scope

This part of GB/T 20730 is applicable to pneumatic and electric industrial process instruments whose measured values are continuous signals that comply with GB/T 777-1985 or GB/T 3369-1989. Other input values (set values) may be mechanical signals (position, force, etc.) or standardized signals. It should be noted that, if the differences between them are properly considered, the tests specified in this part are also applicable to instruments with other continuous measured values. These instruments can be used as controllers or switching devices for alarming and other similar functions. This part is not applicable to instruments with feedback. Electrical safety issues may only affect a small number of products covered by this part, therefore, this part does not mention such safety issues. This part aims to provide a unified test method for evaluating the performance of industrial process instruments that simulate measured values and two-state or multi-state outputs. In addition to performance, other considerations are listed in Chapter 10.
