Bluehex | Musings on Process Instrumentation — Diaphragm Seals

Pressure gauges and diaphragm seals are essential tools for maintaining safety and efficiency in industrial processes, especially in sectors like oil and gas, chemicals, and pharmaceuticals. Pressure gauges measure the pressure of gases or liquids within a system, providing critical data for monitoring and control. Diaphragm seals, also known as chemical seals, protect these gauges from corrosive, viscous, or high-temperature media, ensuring accurate and reliable readings.

Key factors affecting the performance of diaphragm seals include the effective diaphragm area, process pressure, temperature, and fill fluid. These factors influence the sensitivity and overall effectiveness of the diaphragm seals, which in turn impact the accuracy of pressure measurements.
