What Is A Pressure Gauge?

  •   What is a pressure gauge?

      Air manometer is an instrument that measures the pressure of a gas or liquid relative to the atmosphere, the degree of vacuum, or the difference between two points.

      Air pressure gauge suppliers' pressure gauges are widely used in various applications and industries. There are many different types, each of which is best suited for specific tasks and requirements. In short, the pressure gauge provides a simple and direct pressure measurement method.

      What is gauge pressure?

      Gauge pressure is relative to normal atmospheric pressure. Essentially, this is the deviation of the pressure from the standard atmospheric pressure. It can be measured in several different ways, including bar and psi. Gauge pressure is commonly used worldwide, and it is also worth noting that gauge pressure can be positive or negative.

      How does the Air manometer work?

      Different types of pressure gauges work in different ways. For example, the analog version uses a Bourdon tube, while the digital model uses a strain gauge. The following sections provide more details:

      How does the analog pressure gauge work?

      The analog pressure gauge has a curved Bourdon tube. This is a radially formed tube with an elliptical cross-section. When in use, the Bourdon tube will be pulled straight under pressure. The gas or liquid to be measured internally presses on the tube, causing movement at the unclamped end of the tube. Then indicate and use to measure pressure. The Bourdon tube is connected to the dial, and as the pressure increases, the dial rotates clockwise to display the pressure reading.

      How does a digital pressure gauge work?

      The digital pressure gauge has a combination of a microprocessor and advanced sensors. These are used for high-precision measurement of pressure, and the readings are clearly displayed on the screen or digital indicator. Many digital models use strain gauge sensors. These work by monitoring the change in resistivity when pressure is applied. These changes are then measured, and the results are used to calculate pressure readings.
