Sensor system for determining at least one parameter of a fluid medium flowing through a channel structure
First Claim
1. A sensor system for determining at least one parameter of a fluid medium flowing through a channel structure, the sensor system comprising:
- a sensor housing which is inserted or is insertable into a flow pipe and in which the channel structure is formed, the sensor housing having a housing body and a cover, the channel structure having a main channel and a measuring channel, at least one sensor chip for determining the parameter of the fluid medium being disposed in the measuring channel, the sensor housing having an inlet into the channel structure, the inlet pointing counter to a main flow direction of the fluid medium, at least one main-channel outlet from the main channel and at least one measuring-channel outlet from the measuring channel;
wherein the main-channel outlet is located on one of an end face or a downstream side of the cover, based on the main flow direction,wherein the measuring-channel outlet projects (i) downstream of the main-channel outlet based on the main flow direction and (ii) further from the cover than the main-channel outlet.

Abstract
A sensor system for determining at least one parameter of a fluid medium flowing through a channel structure. The sensor system has a sensor housing, particularly a plug-in sensor that is inserted or insertable into a flow pipe and in which the channel structure is formed. The sensor housing has a housing body and a cover. The channel structure has a main channel and a measuring channel. At least one sensor chip determining the parameter of the fluid medium is disposed in the measuring channel. The sensor housing has an inlet into the channel structure, the inlet pointing counter to a main flow direction of the fluid medium, at least one main-channel outlet from the main channel and at least one measuring-channel outlet from the measuring channel. The main-channel outlet is disposed on an end face or on a downstream side of the cover based on the main flow direction.
