SENSOR FOR DETECTING AT LEAST ONE PROPERTY OF A FLUID MEDIUM IN A MEASUREMENT CHAMBER

The invention relates to a sensor (10) for detecting at least one property of a fluid medium (12) in a measurement chamber (14), in particular for detecting a H2 fraction in a measurement gas (16). The sensor (10) comprises at least one sensor element (22) which is designed to detect a thermal condu...

More Information
Summary:The invention relates to a sensor (10) for detecting at least one property of a fluid medium (12) in a measurement chamber (14), in particular for detecting a H2 fraction in a measurement gas (16). The sensor (10) comprises at least one sensor element (22) which is designed to detect a thermal conductivity of the fluid medium (12) and for outputting a measurement signal. The sensor (10) further comprises a branch element (28), which defines an interior space (30), the branch element (28) being designed to branch off a part of the fluid medium (12) from the measurement chamber (14) into the interior space (20), and at least one diaphragm (52, 56, 64). The sensor element (22) is fluidically connected to the interior space (30) by means of the diaphragm (52, 56, 64).
