Scope: This part of GB/T 20730 applies to pneumatic and electric industrial process instruments whose measured value is a continuous signal in accordance with GB/T 777-1985 or GB/T 3369-1989. Other input values (setpoints) can be mechanical signals (position, force, etc.) or normalized signals. It should be pointed out that the tests specified in this standard are also applicable to instruments with other continuous measured values, if due account is taken of the differences therebetween. These instruments can be used as controllers or switching devices for alarms and other similar functions. This section does not apply to instruments with feedback. Electrical safety issues may only affect a small number of products covered by this section, therefore, this section does not address such safety issues. The purpose of this standard is to specify a uniform test method for the performance evaluation of industrial process instruments that simulate the measured value and two or more outputs. In addition to performance, other considerations are listed in Chapter 10.
