01. Air Micrometer Principle
Air gaging is a relative measurement, which is based on the upper and lower standards to achieve precision measurement. The dimensions of the upper and lower standard parts are called absolute dimensions, and the dimensions calculated by the sensor are called relative dimensions, and the absolute dimensions are the key element to guarantee the measurement results. The measuring device in air gaging is called the pneumatic calibration, which includes the air gaging head and the upper and lower standard master. The air gaging head provides the sensing function for dimensional measurement, while the upper and lower standards provide the reference for measurement.
The measurement principle of air micrometer is comparative measurement method. Its measurement method is to convert the length signal into air signal, through the scale of the glass tube inside the buoy to show the value, called buoy type air micrometer; or through the gas-electric converter to convert the gas signal into electric signal by the light tube composed of light column to show the value, called electronic column type air micrometer.

 The air micrometer is a kind of gauge that can be assembled in multiple units, and it can be used with different air gaging head to achieve the measurement of various parameters.

02.Air Micrometer Application
Air micrometer are widely used in the precision machining industry and are characterized by standardization, high accuracy and rapid measurement.
Air micrometer are suitable for automotive, motorcycle, refrigerator and air conditioning compressor, textile machinery, bearings, aerospace and other precision machining industry, can be achieved to measure the inside diameter, outside diameter, height, thickness, width, distance, coaxiality, taper, flatness and other position tolerances of the parts. Air gaging can be adapted to a wide variety of measurement items, without the diversity of pneumatic measuring head design.

03.Air Micrometer Advantages:
Air micrometers are widely used in the machine building industry because of their many advantages. Its advantages are as follows.

1. Measuring items such as length, shape and position errors, etc., especially for certain measurements that are difficult to solve with mechanical gauges and gauges, for example: measuring the internal diameter of deep holes, the internal diameter of small holes, narrow slot width, etc., with pneumatic measurement is easier to achieve.
2. The magnification of the gauge is high, human error is small, will not affect the measurement accuracy; work without mechanical friction, so there is no return error.
3. The operation method is simple, easy to read, able to carry out continuous measurement, and it is easy to see whether each size is qualified.
4. To achieve the measuring head and the measured surface is not in direct contact, reducing the impact of measuring force on the measurement results, while avoiding scratching the surface of the measured parts, especially suitable for the measurement of thin-walled parts and soft metal parts.
5. Due to non-contact measurement, the measuring head can reduce wear and tear, extending the service life. air micrometer body and measuring head are connected by hose, which can realize long-distance measurement.
6. Simple structure, reliable work, adjustment, use and maintenance are very convenient.

04.Air micrometer measuring range:
Inner diameter, outer diameter, slot width, distance between two holes, depth, thickness, roundness, taper, coaxiality, straightness, flatness, parallelism, perpendicularity, aeration and sealing.
