摘 要：
The device relates to measuring
technology and can be used in the energy industry, metallurgy and the chemical industry for determining the concentration of hydrogen in gaseous media over a wide range of temperatures and
pressures. A sensor for sensing hydrogen in gaseous media comprises a working element which, by means of a seal, fits snugly against the upper part of a housing of the sensor. Additional hermeticity is provided by a nut. The lower part of the housing of the sensor is delimited by insulation, which provides close contact with a heater that provides the
temperature conditions of a working medium supplied to a hydrogen-

permeable membrane of a water-steam chamber. Via a platinum measuring electrode, which lies snugly against the lower part of a ceramic sensor element that is hermetically connected by means of a glass ceramic to a metallic housing of the sensor element, the disturbance caused by a measurement flow is
transmitted to a central core of a potential measuring device. A reference electrode is situated inside an inner cavity of the ceramic sensor element. The outer part of the bottom of the ceramic sensor element is coated with a porous platinum
electrode layer. The end of the central core of the potential measuring device extends into the body of the reference electrode. The invention achieves the technical result of increasing the service life and operating reliability of a hydrogen sensor over a wide range of parameters of a working medium by providing for the hermeticity of the inner cavity of the
ceramic sensor element and the stability of the temperature conditions of the
working medium at the inlet to the sensor. 主权项：
