I. Product Introduction

Chuangwei QY series high-pressure gas piston pressure gauges use gas medium and gas lubrication. They operate with high-purity nitrogen or dry, clean gases as the pressure measurement medium, and are used for calibrating pressure instruments and gauges that are oil-free. They can be applied to various calibration needs.Anti-jun laborIndustrial manufacturing, food & pharmaceuticals, metrological inspection, and other fields.

III. Features and Benefits

1、The pressure regulator features easy and convenient pressure adjustment; the pressure system combines coarse adjustment with a gas booster and fine adjustment with the main regulator, ensuring the regulator's handwheel does not move forward or backward during pressure changes, saving workspace and enhancing operation ease. The pressure regulation process is effortless and quick, capable of reaching a maximum pressure of 70MPa.

2、The piston system features stable anti-break design; with anti-break rods and anti-friction structures, it ensures piston performance and extends service life. In case of uneven force distribution and significant shaking after the piston rises and rotates, the two bearings designed into the piston can effectively prevent the piston rod from breaking. The upper limit of the piston is equipped with a bearing limiter, which resolves the issue of metal shavings and piston jamming caused by friction with the limiter screw when the piston reaches its upper position.

3、Versatile selection; extensive range from 1MPa to 70MPa, catering to diverse user needs. Users can self-select high-purity nitrogen or dry, clean air sources based on actual usage frequency.

4、Operation is simple and easy to learn.

The display utilizes a 5-inch TFT LCD IPS color Chinese touch screen.

The piston floating position is displayed, allowing users to quickly and intuitively adjust the piston to the working position.

Display piston speed, providing a direct view of the piston operating speed.

The product can display the ambient temperature and humidity, guiding users to adjust the usage environment. This ensures the piston operates optimally under suitable environmental conditions (temperature: 20±2°C, humidity: 30%~80%), achieving the best performance indicators of the piston.

The piston system is equipped with a piston position displacement sensor, offering a resolution better than 0.1mm, providing more accurate observation of piston balance.
