本刊八○年第九期《流量计改量程二则》一文,介绍了膜片式差压计差压由40mmHg 改为63mmHg 时,认为“使膜片位移超过1mm 时,它的线性也是很好的,这就有可能使这一块膜片,当量程由40mmHg 改为63mmHg 时仍可使用……。”实际上,在测量上限为40和63mmHg 时,是采用同一规格(厚度:0.08mm)的膜片,不存在什么当膜片位移超过1mm 时,还成比例和线性很好的问题。
This issue eighty-ninth period “Flowmeter to change the range of two” article, describes the differential pressure diaphragm pressure gauge from 40mmHg to 63mmHg, that “the diaphragm displacement of more than 1mm, its linear is also very Well, it is possible to make this piece of diaphragm still usable when the measuring range is changed from 40 mmHg to 63 mmHg .... ”In fact, the same gauge (thickness: 0.08 mm) is used for measuring the upper limit of 40 and 63 mmHg, Of the diaphragm, there is nothing when the diaphragm displacement of more than 1mm, but also a very good proportionality and linearity.
