Model HY7000 - Hydrogen Probe with Gauge Assembly for High Pressure Access Systems

Model HY7000 is a high pressure hydrogen probe which can be used for pressures up to 3600psi. Hydrogen probes are commonly used for monitoring hydrogen permeation in steels, which could lead to embrittlement, blistering and decarburisation resulting in the failure of the material. The probe assembly consists of three subassemblies: the gauge assembly, the hollow plug assembly and the sensing element assembly. The gauge assembly consists of a gauge body, a pressure gauge (0-40psi), 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 minimum length of the probe is 5.50 inches and can be ordered in 0.25 inch increments
