When the workpiece surface roughness is large, it is generally recommended to use contact pneumatic measurement, even if the gas momentum meter is used for measurement. This allows the position of the measuring point to remain stationary and at the same time protects the workpiece from friction between the inner wall and the measuring head.
    Aerodynamic measurements are based on the principles of hydrostatics and fluid dynamics,Using compressed air as a medium,The device for measuring the length dimension is applied to the high-precision and high-volume workpiece measurement in the automotive industry. The measuring head is not in direct contact with the measured surface during measurement work,This not only reduces the impact of the measurement force on the measurement result.

    As a precision parts size pneumatic measurement equipment manufacturers, focusing on micro-precision, R & D and production of digital display pneumatic momentum meter, a variety of models, quality assurance, manufacturers direct sales, price concessions.
