Generally speaking, the choice of the gas momentum meter is divided into two parts, one is the choice of the measuring instrument body, and the other is the choice of the measuring head. The following by the billion leride to introduce these two aspects of the purchase.
    1.The choice of measuring instrument body
    Generally its nominal magnification is fixed, magnification has2000Times,5000besum10000Times as many. Therefore, when selecting the gas gauge, different gauge bodies should be selected according to the tolerance of the size of the workpiece to be measured. The selection principle is, if the tolerance bandwidth of the workpiece size to be measured, choose a lower power measuring instrument body; If the dimensional tolerance of the workpiece to be measured is narrow, the higher magnification measuring instrument body can be selected. In terms of accuracy, high precision requirements on the selection of high magnification measuring instrument body, accuracy requirements are not high, with low magnification measuring instrument body can be used.
    2.Selection of measuring head

    The measuring head of the air gauge is made according to the size and tolerance of the workpiece to be measured. Therefore, when selecting the measuring head, it is necessary to comprehensively consider the measurement accuracy and production cost, because the higher the accuracy requirement of the measuring head, the production process has become more complex, so the corresponding cost will also increase.

    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.
