The invention proposes a sensor apparatus (110) for detecting at least one parameter of a fluid medium flowing through a flow pipe (112), comprising at least one housing (114) and at least one sensor element (134), which is accommodated in the housing (114), for detecting the parameter, and a flow pipe. The housing (114) has at least one external housing (120) and at least one internal housing (122) which is at least partially surrounded by the external housing (120), wherein at least one gap, in particular at least one annular gap (124), is formed between the external housing (120) and the internal housing. The housing (114) is formed in such a way that at least a partial flow of the fluid medium can flow into the gap through at least one inlet opening (126) in order to arrive at the sensor element (134) and in order to then flow back into the flow pipe (112) through the internal housing (122) via at least one outlet opening (130). The housing (114) also has at least one retaining element (138). The housing (114) can be connected to the flow pipe (112) by means of the retaining element (138), wherein a portion of the housing (114) projects into the flow pipe (112). The inlet opening (126) is arranged at a distance from an internal wall (144) of the flow pipe (112). The sensor element (134) is arranged outside the flow pipe (112). |
