GB/T 777-1985
AbolishedAnalogue pneumatic signal for industrial process measurement and control instruments
工业自动化仪表用模拟气动信号
Application Summary AI generated
This standard specifies the range and characteristics of analogue pneumatic signals (typically 20-100 kPa) used for transmitting measurement and control information between industrial process instruments. It is applied in the design, manufacturing, and calibration of pneumatic controllers, transmitters, and actuators within process industries such as petrochemical, power generation, and metallurgy. The standard ensures interoperability and signal consistency in pneumatic control loops, particularly in hazardous environments where electronic signals are unsuitable.
