Our PDM200 Automotive hydrogen sensor Hydrogen molecules are adsorbed onto the surface of the titanium alloy film. Under the catalytic action of the film, hydrogen molecules decompose into two hydrogen atoms and diffuse into the interior of the alloy lattice, causing lattice expansion and phase transition, resulting in changes in the conductivity of the alloy film. Based on this characteristic principle, the measurement of hydrogen concentration can be achieved.
