Pneumatic Piston Gauge Gas Deadweight tester
The gas piston pressure gauge uses dry pure air or pure nitrogen as the gas source, and the equipment to be inspected is not polluted. It is mainly designed for clean laboratories, medical industry products and products with high pollution protection levels, etc., and testing sites with high safety requirements. , simpler and safer.
Product introduction

1. Basic Principles


The definition of pressure is the ratio of force on a certain area to that area. The core component is an extremely accurate piston system component, which is loaded with weights to generate the pressure required for the measurement. Both the piston cylinder and the piston rod are made of carbide. This material has extremely low compression deformation and thermal expansion coefficient, which ensures that the cross section of the piston has a good linearity, which makes the accuracy of the instrument very good.


The instrument directly measures the pressure by definition (P=F/S), and the piston system uses high-quality carbide materials, so that the instrument has a very small measurement uncertainty and a long-term stability with a validity period of more than 5 years.


  2. Use environment and selection parameters of piston pressure gauge


1. Use environment: Ambient temperature: (20±1)℃


Relative humidity: constant temperature room below 85%


Power supply voltage: AC 220V


Frequency: 50HZ


There should be no mechanical vibration affecting the metering performance during use

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 equipment to be inspected is not polluted. It is mainly aimed at clean laboratories, medical industry products and products with high pollution protection levels, etc., with high safety requirements. Place design, simpler and safer.


2. Patented piston pressure system components, novel structure, anti-collision, tool-free disassembly, easy to clean the piston system, replace the sealing ring, convenient, fast and safe.


3. 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.


4. The piston display system adopts a 3.5-inch color display screen, which displays the displacement of the piston rod, the temperature and humidity on site.


5. Equipped with two quick interfaces (M20×1.5) of the meter seat, with a stop valve, which can be used for sealing test.


6. The globe valve and pressure regulator are maintenance-free and easy to operate. Reasonable handle design, personalized design according to the hand posture.


7. The main body shell is made of 12mm thick aluminum alloy plate, which is firm and stable.
