现已设计一种玻璃膜片压力计,适用于820℃的温度。它有一个光学或接近光学的平膜片,使不接触地测量压力成为可能。当膜片厚度是0.12毫米、直径是22毫米时,灵敏度是0.01毫米汞柱。
Has now designed a glass diaphragm pressure gauge, suitable for 820 ℃ temperature. It has an optical or near-optical flat diaphragm that makes it possible to measure pressure without touching it. With a diaphragm thickness of 0.12 mm and a diameter of 22 mm, the sensitivity is 0.01 mmHg.
