DEVICE AND METHOD FOR MEASURING HYDROGEN PENETRATION Russian patent published in 2018 - IPC G01N33/20 

FIELD: measurement technology.

SUBSTANCE: invention refers to the determination of the concentration of hydrogen in its mixture with another gas. Method for measuring the content of hydrogen absorbed by penetration into the part in the form of hydrogen atoms includes: provision of the probe containing the capture element, made with the possibility of combining with the mentioned part, wherein the mentioned capture element of the mentioned probe comprises the access opening for receiving the amount of absorbed hydrogen flowing out of the mentioned part; the inlet passage for the measuring gas containing the air and the mixing chamber configured in order to pneumatically communicate with the mentioned inlet passage and with the capture element, provision of the solid-state sensor at the inner section of the mentioned probe in such a way that the mentioned probe and solid-state sensor form the compact device; placement of the probe with the mentioned access opening facing the mentioned part in such a way that the amount of hydrogen flowing from the mentioned part passes through the access opening and enters the mentioned mixing chamber; creation of the flow of the mentioned measuring gas from the inlet passage through the mixing chamber to the mentioned solid-state sensor at the predetermined flow rate; measurement of the concentration of hydrogen in the gas mixture with the solid-state sensor that is pneumatically connected to the mentioned mixing chamber so as to come into contact with the mentioned gas mixture in the mentioned mixing chamber, and generation by the mentioned solid-state sensor the measurement signal responsive to the concentration of hydrogen in the mentioned gas mixture; processing by the processor means connected to the mentioned solid-state sensor, mentioned measurement signal with the calculation of at least one parameter, which is connected with the interaction between the part and the absorbed hydrogen.

EFFECT: higher accuracy and reliability of determination is achieved.
