Pneumatic measuring instrumentIt is used in combination with various pneumatic measuring heads or pneumatic measuring devices to accurately measure the size or shape and position parameters of the measured parts by comparative measuring method. Yileride is a precision parts size pneumatic measurement equipment service manufacturer, independent research and development of gas coulometer, pneumatic measuring instrument and other equipment.

The pneumatic measurement method is based on compressed air as a medium, using the characteristics of the flow or pressure of air in the pipeline with the geometric size and shape of the pipeline to convert the size or displacement into the change of flow or pressure, so as to achieve measurement.

Pneumatic measuring instrument according to the working principle is divided into flow type, pressure type, flow rate type. Among them, the pressure type gas momentum meter is often used for active measurement because it is easy to send signals; Flow type and flow rate type are suitable for static measurement and are mostly used for inter-process detection.

Characteristics of pneumatic measuring instrument

The pneumatic measuring instrument is a kind of measuring instrument which can be assembled by multiple sets. It can be matched with different pneumatic probes to measure various parameters. Because of its own many advantages, the air momentum meter has been widely used in the machinery manufacturing industry. Its advantages are as follows:

1There are many measurement items, such as length, shape and position errors, etc., especially for some measurements that are difficult to be solved with mechanical measuring tools and measuring instruments, such as: the inner diameter of the sounding hole, the inner diameter of the small hole, the width of the narrow slot, etc., it is easier to achieve with pneumatic measurement.

2The magnification of the measuring instrument is high, and the human error is small, which will not affect the measurement accuracy; There is no mechanical friction during operation, so there is no return error.

3The operation method is simple, the reading is easy, the continuous measurement can be carried out, and it is easy to see whether the sizes are qualified.

4The measuring head is not in direct contact with the measured surface, reducing the impact of the measuring force on the measurement results, while avoiding scratching the surface of the measured part, especially for the measurement of thin-walled parts and soft metal parts.

5Due to non-contact measurement, the measuring head can reduce wear and extend the service life. A hose connection is adopted between the main body of the gas gauge and the measuring head to realize remote measurement.

6Simple structure, reliable work, adjustment, use and maintenance are very convenient.

Yileride continues to deepen the field of precision parts size pneumatic measurement, independent research and development of gas coulometer, pneumatic measurement core components, product accuracy through the Shanghai Institute of Metrology, Jiangsu Institute of Metrology and other third party testing certification. Pneumatic probe selected German steel, to ensure the probe wear resistance and long life. Accumulated service thousands of enterprises, the quality is trustworthy and choice.
