WIKA: Advantages of diaphragm pressure gauges: Solutions for critical media
September 2021
MARIETTA, GA ~
Diaphragm pressure gauges are genuine multi-purpose instruments. For example, in processes with critical media, they enable comprehensive possibilities for reliable pressure measurement with long-term stability.
Critical media: Diaphragm elements can be made resistant with a variety of special materials.
Aggressive media
In addition to the resistance, the special material must also meet the elasticity and sealing required for the measuring task. The diaphragm of the diaphragm pressure gauge is usually glued with a foil of the selected material or, in the case of gold and platinum coating, it is galvanised. In some cases, the diaphragm element is even made entirely from the special material.
For applications with
particularly aggressive media, the lower flange of the diaphragm can
also be lined with the special material. The wetted area of the
measuring instrument is then completely protected.
Viscous and similar media
Sensitive media
