Ten years experience manufacturing Hydrogen Energy Sensor

Product description

The diaphragm of the hydrogen pressure sensor, forming the H molecule, remains in the pressure transmitter, and the H gradually dissolves in the liquid silicone in the pressure transmitter. After a period of time, the hydrogen in the silicone is saturated and bubbles are formed. The bubble will cause the zero point movement, affect the measurement results, and lead to the transmitter performance degradation. When hydrogen is increased, the diaphragm will also expand outwards, causing cracks, silicone outflow, and the failure of the pressure transmitter. If pure hydrogen is present in some applications, penetration problems are bound to occur. However, if it does not appear like pure hydrogen, osmosis will occur. That's because hydrogen atoms are constantly breaking away from molecules to become ions. The membrane of the hydrogen pressure sensor affects permeability because the lattice gaps vary with the material molecules. Traditionally, the diaphragm is made of stainless steel, avoiding the use of nickel-based metals such as Herc. Tantalum, of course, is an expensive plate made of gold-plated stainless steel, but it is protective because the penetration can be eliminated by plating 3m thick gold.
