Applications
Diaphragm seal pressure gauges are used to measure pressure in corrosive, high-viscosity, crystallizing, or particle-containing media. The diaphragm seal protects the internal sensing element from direct contact with the process fluid, ensuring stable and reliable measurement in harsh industrial conditions.
