| 摘要 |
The invention relates to a sensor assembly. The assembly includes a multi-layer sensor body (2) of appropriate construction (preferably substantially ceramic). A preformed ceramic disc (8) is bonded to a front part of the sensor body (2) to provide a hermetic seal that excludes gas from any interface between the constituent layers of the sensor body (2). The hermetic seal is maintained even if the sensor assembly is used at high operating temperatures. |
