Quelles sont les utilisations des manomètres diaphragme pression?
When measuring the pressure of general gases, water, and oil, a general pressure gauge can be used: when measuring nitric acid. Stainless steel pressure gauges can be used for the pressure of phosphoric acid and strong alkali. However, when the measured medium has strong corrosiveness (such as hydrochloric acid, wet chlorine gas, ferric chloride), high viscosity (such as latex), easy crystallization (such as salt water), easy solidification (such as hot asphalt), and solid floating matter (such as sewage), it is not feasible to use the above pressure gauge again because even SUS316 stainless steel pipes will be corroded by hydrochloric acid, and the floating matter in asphalt and sewage will quickly block the pressure gauge's pressure hole, causing the instrument to lose its function. Diaphragm pressure gauges can solve these problems, and people can choose different corrosion-resistant diaphragm materials according to different strong corrosive media to achieve anti-corrosion effect.
