Gas companies use pressure switches mainly to monitor and control the pressure in the gas pipeline to ensure the safe and stable operation of the system, and automatically take measures when the pressure is abnormal, such as cutting off the gas flow or adjusting the pressure, to protect the equipment and prevent accidents. However, to ensure the accuracy and stability of the pressure switch, regular calibration is essential. Therefore, the application of measurement and calibration equipment such as pressure calibrators and pressure calibration benches is very important.

The calibration of the pressure switch is a key step to ensure that its readings are accurate and responsive. Once an error occurs in the pressure switch, it may cause false alarms or missed alarms, which will bring hidden dangers to the safe operation of the natural gas system. Therefore, using professional pressure calibrators and pressure calibration benches for calibration is a necessary means to ensure the stable and reliable performance of the pressure switch.

The pressure calibration bench can provide a stable and controllable pressure environment for accurate calibration of the pressure switch. The PR9120 pressure calibration bench is an efficient and accurate fully automatic pressure calibration system suitable for the calibration of a variety of pressure instruments. It uses a variable speed motor to drive a piston pump to generate pressure, and an intelligent controller to accurately control the pressure increase and pressure reduction. It has rapid pressure generation and high stability, and is suitable for calibrating a variety of pressure instruments, such as transmitters, switches and indicators, to meet the needs of natural gas companies to establish standard pressure laboratories.

The PR9112 intelligent digital pressure calibrator is a portable, multi-functional calibration tool designed for pressure calibration. It can measure pressure, current, voltage, check switch status and time, support multiple triggering methods, record pressure peaks, and store and export data. Whether it is calibrating pressure transmitters, switches, precision gauges or general pressure gauges, PR9112 is efficient, accurate and convenient.

The calibration of pressure switches is crucial to the safe operation of natural gas systems. The application of pressure calibration benches, pressure calibrators and other equipment not only reduces the errors caused by human operation, but also ensures the accuracy and stability of pressure switches, providing strong guarantees for the long-term stable operation of natural gas systems.
