车床和铣床加工零件的尺寸,可用敏感元件为气流式一次测量变换器的宽量程测量装置来检验。变换器的工作原理是:变换器管路中的空气压力是随其相距零件表面距离的变化而变化。使用这种装置的实践表明,为准备气源而对它们装备专用的系统,在经济上是不合算的。在气流式变换器中,利用水油分离过滤器 Lathe and milling machine processing parts size, the sensor can be used for air-flow measurement of a wide range of measuring devices to test. The working principle of the converter is: the pressure of the air in the converter pipe varies with the distance from the surface of the part. The practice of using such devices has shown that it is economically uneconomical to equip them with a dedicated system for the preparation of a source of gas. In the gas flow converter, a water-oil separation filter is used
