化學密封
該組合化學密封/壓力儀表解決測量問題，壓力表不能沒有化學密封，如：
1，該介質不能進入測量元件內部
2，浸濕零件必須使用黃銅/青銅或不銹鋼以外的材料，哈氏合金，Monel合金，鉭，鎳或鈦
3，加工和構造導致在衛(wèi)生方面的高要求
4，壓力儀表不適合介質點的溫度
基本上，由工藝連接和膜片組成的化學密封，是分離元件，可阻止介質流入測量工具里。
膜片和波登管尾端的空間是排空的，用合適液體充液并完全閉合密封。
化學密封直接安裝焊接或冷卻化學密封和壓力儀表間的毛細管線元件。

Chemical Seals
This combination chemical seal / pressure gauge solves measuring problems, that are not possible for a pressure gauge without chemical seal, like
• the medium should not get into the measuring unit
• the wetted parts have to be made of other materials than brass/bronze or stainless steel, e.g. hasbloy alloy, monel, tantalum, nickel or titanium
• processes and instructions make high demands on the hygiene
• pressure gauges are not suitable for the temperature at the point of the medium
Basically, chemical seals consist of a body with process connection and a diaphragm as separating element, that avoids that the medium gets into the measuring unit.
The space between diaphragm and the end of the bourdon tube is evacuated, compleby filled with a suitable liquid and closed hermetically.
The mounting resp. welding of the chemical seal happens directly or with cooling element resp. capillary line between chemical seal and pressure gauge.
