| 摘要 |
The invention relates to a sensor assembly. The assembly includes a sensor body (2) of appropriate construction (preferably substantially ceramic) with a radial flange (8). A housing (20) is of two-part integral construction and includes an annular groove or recess in which the radial flange (8) of the sensor body (2) is received when the sensor assembly is in its assembled form. The annular groove is defined by a pair of facing shoulders (28, 36) each having an annular surface (30, 38) and a substantially cylindrical surface (32, 40). The annular surfaces (30, 38) are in sliding contact with the flange (8) and apply a compressive load to the flange to form a hermetic seal between the housing (20) and the sensor body (2). The hermetic seal is maintained even if the sensor assembly is used at high operating temperatures. |
