GB/T 20819.1-2007 Controllers with analogue signals for use industrial-process control system Part 1: Methods of evaluating the performance (English Version)
GB/T 20819 applies to pneumatic and electric industrial process controllers with continuous analog input and output signals in compliance with current national standards. The tests specified in this part of GB/T 20819 are applicable to controllers with the same principle but different signals but all are continuous signals. This evaluation method can also be used for equipment that uses digital principles internally and has conventional analog input and output signals. The purpose of this standard is to specify uniform test methods for the performance evaluation of industrial process controllers with analog input and output signals. When it is not necessary to conduct a comprehensive assessment according to this part, the required tests can be carried out according to the relevant parts of this part, and the test results should be reported. Manufacturers and users should reach an agreement on the test procedures according to the characteristics and scope of use of the equipment.
