Sensors of explosive gases are in a high demand and are used in coal mining, oil and gas industry, electricity, telecommunications as well as in housing sector. The key component of a gas sensor is a photovoltaic cell that reacts to changes in the infrared irradiation that occur if propane, methane or ethylene enter the measuring cell.
Company Optosens developed a transducer that uses a nanosized layer of the dielectric material — polycrystalline lead, cadmium and selen- in which the light induced electric current (photovoltaic effect) occurs. Reduced thickness of the dielectric layer makes the sensor remarkably energy-effecient, fast and reliable in extreme conditions. In this infographics we demonstrate the structure of the sensor and the location of the photogalvanic and protective layers in the infrared irradiation transducer.
