What is a chemical seal?

A chemical seal makes sure the pressure transmission in a medium can be performed, while the medium is maintained separated from the instrument itself. Without a chemical seal, aggressive, toxic, corrosive, or viscous materials would damage pollute the interior of the pressure gauge. In other words, a chemical seal is a type of barrier between the medium and the measuring instrument.

So, what does that look like? A chemical seal is a case, closed by a (stainless steel) diaphragm, filled with an appropriate fluid or gel that transmits the pressure of the medium. In some cases, a capillary is used.

The working of a pressure gauge with chemical seal

To read pressure with a pressure gauge with chemical seal, the medium is connected to the manometer, where it is lead to the chemical seal through a pipe or tube. The diaphragm transmits the pressure to the fluid or the capillary. This activates the pressure measuring mechanism in the pressure gauge itself.

Application of chemical seals

Chemical seals are very commonly used in food and pharmaceutical industries, but also in chemical processes and in oil and gas industries. The measured media in these types of industry often are aggressive or can pollute the mechanism of the pressure gauge easily. That is why a pressure gauge with chemical seal is essential to maintain pressure measuring reliable and safe and optimize the instruments’ lifespan.
