| Model HY4000 is a high pressure hydrogen probe which can be
used for pressures up to 1,500 psi. Hydrogen probes are commonly used for monitoring
hydrogen permeation in steels, which could lead to embrittlement, blistering, and
decarburization resulting in the failure of the material. The probe assembly consists of
three subassemblies: the gage assembly, the insertion rod sensing element assembly, and
the packing gland assembly. The gage assembly consists of a gage body, a pressure gage
(0-40 psi), a temperature gage, and a bleed valve. The sensing element is about 3.5 inches long and consists of a thin-walled tube which is sealed from the process and allows nascent hydrogen to permeate. The probe can be supplied with or without the gage assembly, which can be bought separately if required. |
