    DP Gauge Structure

    Differential pressure gauge structure


    Q1: Can a differential pressure gauge measure both positive and negative pressure differences?
    A1: Yes, a differential pressure gauge can measure both positive and negative pressure differences between two points. It is designed to indicate the difference regardless of which side has the higher pressure.

    Q2: Can a differential pressure gauge be used in high-temperature environments?
    A2: It depends on the specific gauge and its construction materials. Some diff pressure gauges are designed to withstand high temperatures, but it is important to check the manufacturer's specifications to ensure suitability for high-temperature applications.

    Q3: Can I calibrate a differential pressure gauge myself?
    A3: Yes, you can calibrate a differential pressure gauge if you have the proper equipment and follow the correct procedures. Calibration should be done using a known reference standard, and the process may vary depending on the gauge type. For critical applications, professional calibration services are recommended.

    Tips: Can I use a differential pressure gauge to measure vacuum pressures?

    Yes, differential pressure gauges can be used to measure vacuum pressures, as long as they are designed to handle the low-pressure conditions typical in vacuum applications. Ensure the gauge's range includes the vacuum pressure you need to measure.
