<p>A hydrogen concentration measuring device comprises a measuring cell (1) with an acoustic resonator, an electroacoustic component (2, 3) for activating and detecting acoustic signals associated with the resonator and an electronic control unit (4) for generating an output signal corresponding to the hydrogen concentration in real time. A device for measuring the concentration of hydrogen in a gas mixture includes at least one measuring cell with one or more acoustic resonators having a resonance frequency monotonally dependent upon the hydrogen concentration in the gas mixture at one or more frequency intervals between a level corresponding to the presence of hydrogen to a level corresponding to pure hydrogen. At least one electroacoustic component is used to activate and detect acoustic signals associated with the resonator at these frequency levels. At least one electronic control unit generates one or more output signals which correspond to the hydrogen concentration in real time and are a monotone function of the resonance frequency.</p> |
