Hydrogen Probe
Retractable with Packing Gland |
View data sheet (PDF) |
Model HY4000 is a high pressure hydrogen probe which can be used for pressures up to 2,000 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 gauge assembly, the insertion rod sensing element assembly, and the packing gland assembly. The gauge assembly consists of a gauge body, a pressure gauge (0-40 psi), a temperature gauge, 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 gauge assembly, which can be bought separately if required.
The Easy Tool is required for probe insertion or retraction in systems with pressure over 150 pounds.
