The common faults, causes, and troubleshooting methods of pneumatic measuring instruments are summarized in the table below. When using these instruments, please pay attention to the following important points: First and foremost, ensuring a clean gas source is essential for the proper functioning of the pneumatic measuring instrument. To achieve this, it's recommended to install a high-capacity filter before the instrument’s own filter. Regularly drain and replace the water trap to prevent moisture from entering the system, which can cause damage or inaccurate readings. In addition, make sure that the air pressure supplied to the instrument is not less than 3 kgf/cm². Avoid placing the device in areas exposed to direct sunlight or where temperature fluctuations are significant, as extreme conditions can affect its performance and accuracy. It's also important to check and replace the plastic tubing regularly, as worn or damaged tubes can lead to leaks or inconsistent measurements. When you restart the instrument after closing the intake valve, always use a standard part to recalibrate both the zero position and the magnification factor. This ensures that the instrument remains accurate and reliable over time. Always operate the measuring instrument within its effective range, as exceeding this may result in incorrect readings or even damage to the equipment. Moreover, the measuring gap of the measuring head should never exceed the maximum allowable gap specified by the manufacturer. Exceeding this limit can lead to measurement errors or mechanical failure. By following these guidelines, you can extend the life of your pneumatic measuring instrument and maintain its precision during daily use.
