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.

3. Functional characteristics of piston pressure gauge
1. Patented piston pressure system components, novel structure, anti-collision, tool-free disassembly and assembly, easy to clean the piston system and replace the sealing ring, convenient, fast and safe.
2. The small area and small weight piston has been successfully developed and tested and has been put into production. It is more convenient and easy to use, greatly reducing labor. Customers can choose according to the situation or call for consultation.
3. The piston displacement data is collected using two infrared distance measuring sensors, which are converted through a self-designed circuit system and displayed on the LCD screen, making displacement observation more convenient and accurate.
4. The piston display system uses a 3.5-inch color touch screen to display piston rod displacement, on-site temperature and humidity.
5. Equipped with two gauge seat quick connectors (M20×1.5) with stop valves (optional) for sealing tests.
6. 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.
7. The main body shell is made of 12mm thick aluminum alloy plate, which is strong and stable. The oil cup has an oil storage capacity of 400ml. It can be customized to enlarge the oil cup according to customer needs to facilitate the calibration of large quantities of sensors. The cup is equipped with an oil filter. The pipeline at the meter socket is directly connected to the oil cup and passes through the sewage filter to ensure the cleanliness of the oil entering the piston system, avoiding dirty oil from entering the piston system to cause blockage and damage, or even causing the piston rod to get stuck and break.
8. The oil system has a sewage discharge function, making the maintenance and cleaning process simpler and more convenient.
9. The piston display part is equipped with a touch switch and displacement calibration button. Quick instructions for displacement calibration can be displayed on the screen through operation, which is convenient for customers to use.
