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 an H2 fraction in a measurement gas (16). The sensor (10) comprises at least one sensor element (22) which is designed to detect the thermal conductivity of the fluid medium (12) and to output a measurement signal. The sensor (10) further comprises a branching element (28) which delimits an interior (30), the branching element (28) being designed to branch a part of the fluid medium (12) from the measurement chamber (14) into the interior (30), and at least one diaphragm (52, 56, 64). The sensor element (22) is fluidically connected to the interior space (30) by means of the partition (52, 56, 64). 提出一种用于检测测量室(14)中的流体介质(12)的至少一种特性的传感器(10)，尤其用于检测测量气体(16)中的H2份额。所述传感器(10)包括至少一个传感器元件(22)，该传感器元件构造用于检测流体介质(12)的热传导性并且用于输出测量信号。所述传感器(10)还具有分支元件(28)和至少一个隔板(52，56，64)，该分支元件限定一内部空间(30)，其中，该分支元件(28)构造用于将流体介质(12)的一部分从测量室(14)分支到所述内部空间(30)中。传感器元件(22)借助于所述隔板(52，56，64)与所述内部
