Model HY7000


Hydrogen Probe with Gage Assembly
for High Pressure (HPTM and MHTM) Access Systems

Model HY7000 is a high pressure hydrogen probe which can be used for pressures up to 3,600 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 hollow plug assembly, and the sensing element 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 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. The minimum length of the probe is 5.50 inches and can be ordered in 1/4 inch increments.
