Gauges with chemical seal

EMVO Techniek – Also for specialized manometers with chemical seals

A pressure gauge with a chemical seal is a specialized type of manometer equipped with a seal or diaphragm that is resistant to chemical substances. This chemical seal protects the manometer from corrosion or damage caused by aggressive media found in certain industrial applications. Essentially, it acts as a barrier between the medium and the measuring instrument itself.

• PTFE (Polytetrafluoroethylene)
• FKM (Fluor elastomer)
• EPDM (Ethylene Propylene Diene Monomer) or other specialized elastomers.

When do you need a pressure gauge with a chemical seal?

Manometers with a chemical seal have a chemically resistant seal placed between the measuring instrument and the medium to be measured. This protects the manometer from direct contact with aggressive media and prevents damage or corrosion. These manometers are especially popular in industries such as chemical, petrochemical, pharmaceutical, and food processing, where aggressive liquids, gases, or vapors are common. The chemical seal ensures that the gauge operates reliably in such environments without compromising accuracy or durability.

A pressure gauge with chemical seal: how does it work?

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 pressure gauges with chemical seals

A manometer with a chemical seal is typically used in the chemical industry, petrochemical industry, pharmaceutical industry, water and wastewater industry, and environmental engineering. Using pressure gauges with chemical seals allows companies to extend the lifespan of their measuring instruments in demanding environments and ensure the accuracy of pressure measurements. This helps reduce downtime and improve the reliability of process monitoring.

Choose the right manometer

When selecting a manometer with a chemical seal, it is important to carefully consider the specific requirements of the application and the properties of the media to ensure optimal performance and safety. We are, of course, happy to assist you in making your choice.
