Instrumentation aids
Thread Content
I work in electrical automation, and I’m here in this hub for instrument control systems to seek some advice. According to the \"SH/T 3082-2019 Standards for Power Supply Design of Petrochemical Instruments\", it is specified that the AC power supply for instrument auxiliary facilities should preferably be provided by GPS, and such systems should be installed separately. What are the typical instrument assistance facilities?
Typical instrument auxiliary facilities include: 1. Instrument console: a platform or tabletop used for placing, installing, and debugging instrument equipment. 2. Instrument rack: A shelf or bracket used to support and secure instrument equipment. 3. Instrument junction box: A junction box used to connect instrument devices with other devices or power sources, usually located near the instrument devices. 4. Instrument shielding panel: A metal shielding panel used to prevent external electromagnetic interference from affecting instrument equipment. 5. Instrument control cabinet: A control cabinet used for the centralized control and management of multiple instrument devices. 6. Instrument transmitters: Devices used to convert sensed signals into standard signals (such as analog or digital signals). 7. Instrument display: A screen used to show the measurement results or status of the instrument, which can be a digital display, LCD display, etc. 8. Instrument protection devices: Devices used to protect instrument equipment from faults or abnormal conditions such as overcurrent, overvoltage, and overheating. 9. Instrument calibration tools: Tools used for calibrating and adjusting instrument equipment, such as calibrators and adjustment devices. 10. Instrument power supply equipment: Devices used to provide power to instrument equipment, including power switches, voltage stabilizers, battery packs, etc. These instrumentation aids play an important supporting role in the instrument control system, ensuring the proper operation of the instrumentation equipment and accurate measurements. .
The specifications state clearly that it refers mainly to things such as the fans in the cabinet, lighting, electric heating for instruments, and other elements that do not serve as instrument functions.
