1. Basic principles
Pressure is defined as the ratio of force on a certain area to that area. The core component is a highly accurate piston system component, which generates the pressure required for measurement by loading weights on the component. The piston cylinder and piston rod are made of tungsten carbide, which has extremely low compression deformation and thermal expansion coefficient, ensuring that the cross-section of the piston has good linearity, making this instrument very accurate.
The instrument measures pressure directly by definition (P=F/S), and the piston system is made of high-quality tungsten carbide material, which makes the instrument have extremely small measurement uncertainty and long-term stability with a validity period of more than 5 years.
2. Piston pressure gauge use environment and selection parameters

3. Functional characteristics of gas piston pressure gauge
1. The gas piston pressure gauge uses dry pure air or pure nitrogen as the gas source, and the tested equipment is not contaminated. It is mainly designed for clean laboratories, medical industry products, products with a high level of pollution protection, and other testing places with high safety requirements. It is simpler and safer.
2. Patented piston system bracket assembly, the piston system is more stable to use.
3. The product upgrade adds an air intake flow control valve to more carefully and accurately control the air intake flow, avoiding the inevitable damage to the piston system and the instrument under test caused by excessive air intake.
4. The display part has been upgraded to adopt a 3.5-inch color LCD touch display system, adding functions such as temperature, humidity, and pressure (convertible to MPa, kPa, psi, bar) display.
5. The performance of the pressure regulating system is better than that of the oil pressure regulating system. The pressurization process is easy, it is not easy to leak pressure, and it is maintenance-free.
6. The piston pressure gauge is equipped with a high-precision pressure sensor (convertible to MPa, kPa, psi, bar) to display the pressure value in real time.
7. The piston pressure gauge air inlet valve and pressure relief valve are upgraded to flow control valves, making them easier and more convenient to use.
8. Equipped with two gauge seat quick connectors (M20×1.5) with stop valves (optional) for sealing tests.
9. The stop valve (optional) and pressure regulator are maintenance-free and easy to operate. The handle is reasonably designed and personalized according to the hand-holding posture.
10. The mainframe shell is made of 12mm thick aluminum alloy plate, which is strong and stable.
