Hydrogen Permeation Hydrogen Permeation is the penetration of hydrogen ions through the thin metal isolation diaphragms of a pressure transmitter. Over time, this penetration will cause errors in measurement. Hydrogen is normally found in nature in a diatomic state (a H2 molecule). In this state, hydrogen cannot penetrate the thin (0.001 inch to 0.002 inch…
