Application of pressure transmitters and calibration equipment in HVAC systems

In HVAC systems, pressure transmitters play a vital role. They can accurately measure static pressure, dynamic pressure and differential pressure in air ducts to adjust wind speed, air volume and air pressure. Through accurate pressure measurement, the system can achieve more accurate temperature and humidity control and create a comfortable indoor environment. To ensure the accuracy of pressure transmitters, the application of pressure calibration benches and pressure calibrators is particularly important.

The PR9120 fully automatic pressure calibration bench uses a variable speed motor to drive a piston pump to generate pressure, and the intelligent controller intensively regulates the pressurization and decompression processes. The pressure is generated quickly and stably without fluctuations. It is suitable for calibrating a variety of pressure instruments, such as transmitters, switches and indicators, meeting a wide range of needs and complying with calibration regulations.

The PR9112 intelligent digital pressure calibrator is a compact, high-precision portable tool. It integrates an intelligent pressure module and a convenient host, has a friendly operation interface, supports self-calibration, and ensures accurate measurement. The device is easy to carry and also supports voltage and current measurement and output. Connecting to the computer through the RS232 interface and combining with the calibration software can effectively improve the calibration efficiency of various pressure transmitters, pressure sensors and other pressure instruments.

In the daily maintenance and care of HVAC systems, regular calibration using pressure calibration benches and pressure calibrators has become a standard operating procedure. This not only helps to improve the overall performance of the system, but also effectively extends the service life of the equipment and reduces maintenance costs.
