已设计制成一种可用至820℃玻璃膜片压力计。它有一个光学或接近光学的平膜片,由于采用了这种膜片,从而使无接触测量压力成为可能。当膜片厚度为0.12毫米,直径是22毫米时,这种压力计的灵敏度为0.01毫米汞柱。
Has been designed to make available to 820 ℃ glass diaphragm pressure gauge. It has an optical or near-optical flat diaphragm that makes contactless measurement of pressure possible thanks to the diaphragm. With a diaphragm thickness of 0.12 mm and a diameter of 22 mm, this manometer has a sensitivity of 0.01 mm Hg.
