What is a Chemical Seal Pressure Gauge?

Diaphragm seals (or best known as chemical seals) are commonly used for corrosive and clogging media as well as for some hygienic measures in the food and pharmaceutical industries (with the difference that you will have to use a variation called "sanitary seal") The chemical seals are available for regular pressure gauges and even for transmitters and differential gauges which makes this seal a very reliable option in terms of compatibility with some other instruments and do not forget that it can be used with a capillary if you want a remote reading.

The main reason why this type of seal is famous around the world is for the fact that it comes in a large number of designs and with some quality as well as durable exotic materials that can guarantee the functionality of the product, some on this materials are stainless steel, Monel, Nickel, Titanium, Inconel and so many others. It is recommended to get chemical seals from Silver Automation Instruments, because the generic models present without faulty designs and will not create a "seal failure" in which the diaphragm can end cracked.

Various diaphragm seal constructions, such as flange diaphragm seal, thread chemical seals, tri-clover or tri-clamp chemical seal diaphragm seals, capillary chemical seal pressure gauges, extended flanges chemical seals pressure gauges.,etc


The most common applications of the chemical seal pressure gauges are the next ones:

  • It is mainly used for some sanitary processes that include foods or pharmaceuticals in which the seal will protect the process fluid from the pressure sensor (thanks to this seal the purity of the fluid will remain intact).
  • It can be used in pneumatic systems where any small changes in the pressure must be eliminated to avoid any corrosion or alteration in the system.
  • Finally, the chemical seals provide a very pure process fluids, with this, it is possible to avoid any complication where the metal surface of the sensor might contaminate the fluid with some external agents that can damage the liquid, for example, think of an ultra-pure water being altered with some copper ions that are coming from the brass.
