Sensor arrangement for exhaust gas system to determine oxygen content in exhaust gas, has glass pane arranged between fastening part and substrate body, and radiation-reflecting or absorbing thermal shield formed between pane and body end

摘要

The arrangement has a longitudinally-extending substrate body (1) comprising a ceramic rod and two ends for accommodating and/or connecting measuring connection lines, where one of the ends has higher temperature than that of another end. A sleeve or flange-like fastening part (3) has a passage opening for accommodating the body, where the body is connected with the fastening part by glass fusing. A glass pane (2) is arranged between the fastening part and the body, and a radiation-reflecting or radiation-absorbing thermal shield is formed between the pane and the former end of the body.
