Product Features
The QFB/A-type buoy pneumatic gauge has the advantages of stable performance, reliable operation, simple structure, high measurement accuracy, convenient operation and non-contact measurement, which is widely used in the machinery industry. It can be used to measure the following parameters: inner diameter, outer diameter, thickness, height, depth, flatness, straightness, roundness, parallelism, coaxiality, groove width, center distance, etc. According to the customer's measurement needs, we can provide various types of special pneumatic measuring devices.
Compared with mechanical measuring instruments and measuring instruments, buoy pneumatic measuring instruments have the following characteristics
◆ It can measure various dimensional parameters, shape and position tolerances of the workpiece, especially for some mechanical measuring tools and measuring instruments that are difficult to solve, such as the inner diameter of the sounding hole, the inner diameter of the small hole, the width of the narrow groove, etc. It is relatively easy to realize with a pneumatic measuring instrument;
The magnification of the measuring instrument is high, the human error is small, and the measurement accuracy will not be affected; there is no mechanical friction when working, so there is no return error;
◆ The operation method is simple, easy to read, and continuous measurement can be carried out; especially when using a multi-tube pneumatic gauge, it can be seen at a glance whether each size is qualified when measuring multiple sizes at the same time;
◆ The measurement head is not in direct contact with the measured surface, which reduces the influence of the measurement force on the measurement results and avoids scratching the surface of the measured piece. It is especially suitable for the measurement of thin-walled parts and metal parts. Due to the non-contact measurement, the measuring head can reduce wear and prolong service life;
◆ The main body of the pneumatic gauge is connected with the measuring head by a hose, and the position of the gauge and the measured part is convenient and flexible;
◆ Simple structure, reliable work, adjustment, use and maintenance are very convenient.
