Fuji Hydrogen Permeation Resistant Type Presure transmitter
1. Product introduction:
The phenomenon of "hydrogen" and "hydrogen permeability" has always plagued the engineering technology community in measurement of hydrogen pressure. Once the hydrogen is leaked, it may have unimaginable consequences. At present, most of the pressure transmitters on the market cannot be directly used to measure the pressure of hydrogen, because the materials used in these products do not have the ability to resist and resist with hydrogen resistance. The resistance hydrogen -resistant pressure transmitter produced by Fuji is the world's first dual -coating structure. By plating the surface of the isolated film and the structure of the ceramics (double -plated) structure, it suppresses the hydrogen permeability inside the filling irrigation fluid.

3：Application case
This transmitter has been widely used in the coal chemical industry in Shanxi. The company's gas chemical furnace uses 86 Fuji ydrogen Permeation Resistant Type Presure transmitter. Gold has good denseness, erosion resistance and ductility in use. Later, the H2 penetration in the medium of gasification was effectively prevented, and the problem of measurement of membrane hydrogen and hydrogen perception to the measurement of the diaphragm pressure transmitter was effectively solved.
The gold -plated septum pressure transmitter is widely used in gasification furnace conditions. Because of its following advantages: the gold -plated layer is very thin, it is a micron -level thickness, it solves the problem of hydrogen permeability. The effect of sexual sensitivity to the pressure of the membrane can be ignored. While ensuring the measurement accuracy, it also ensures the real -time response of the entire measurement system, which perfectly solves the difficulty of such working conditions. In order to target severe wear conditions, two gold -plated layers of different thickness have been developed in a targeted manner to solve such problems more effectively and targeted
