Sensor Arrangement

The invention relates to a sensor arrangement for detecting electromagnetic radiation whose wavelength in or near the infrared range, with at least one measuring chamber (2), which is filled with the radiation to be measured selectively absorbing fluid, the measuring chamber (2) by a windows (3) sealed entry port for the radiation and part of the Messkammerwandung having a flexible membrane (M) is designed such that, when a volume change in thethe measuring chamber (2) contained fluid is deformed due to the absorption of the incoming radiation, and wherein the membrane (M), a measuring device is assigned to capture the deformation, which is characterized in that at least at the measuring chamber (2) opposite side of the membrane (M) is a pressure relief chamber (7) is formed,

what with the measuring chamber (2) is in fluid communication.
