  隔膜密封是一种用于 → 测量设备的压力密封,将设备与过程隔离,以防止被测压力的介质进入测量系统。这可以保护测量仪器免受腐蚀性、高粘性或固化介质以及高温介质的影响。隔离膜片还可以减弱测量压力的波动和尖峰,并增强仪器的 → 过载限制。此外,它们还可以在狭窄的空间、爆炸性环境和无死角的情况下安装压力计。

  原文:

  Diaphragm seals are a type of pressure seal for → measurement devices, separating the device from the process to prevent the medium whose pressure is being measured from entering the measuring system. This protects the measuring instruments from aggressive, highly viscous, or solidifying media as well as from high medium temperatures. Isolating diaphragms also attenuate fluctuations and sharp peaks of the measured pressure and enhance the → overload limit of the instrument. Additionally, they make it possible to install manometers in constricted spaces, explosive atmospheres, and without dead spaces.
