腐蚀性介质是液体或气体，可通过持续接触对传统材料造成损坏。例子包括酸，但也包括盐水。在腐蚀性介质中测量压力和温度时，与介质接触的传感元件必须由特别坚固的材料制成，例如哈氏合金、钽或某些专用塑料。

　　Aggressive media are liquids or gases which can cause damage to conventional materials through sustained contact. Examples include acids, but also salt water. When measuring pressure and temperature in aggressive media, the sensing element in contact with the medium must be made from particularly rugged materials such as Hastelloy, tantalum, or certain specialised plastics.
