气体测量传感器
摘要：
确定被测气体的物理特性、尤其是其温度或气体混合物如内燃机的排气中的气体成分的浓度的气体测量传感器，具有管状的壳体及保持在壳体中的传感元件(11)，它以被测气体侧的端部区段(111)及连接侧的端部区段(112)从壳体伸出并在端部区段(111，112)之间相对壳体密封。为实现端部区段(112)相对被测气体——端部区段(111)暴露于其中——在制造技术上简单且可靠地密封并减小整个传感器的轴向结构高度，传感元件承载一个环形法兰(13)，它设置在端部区段(111，112)之间的区域中并与传感元件气密地连接。壳体中构造有环形的径向肩(123)，环形法兰(13)通过置于径向肩与它之间的密封圈(14)轴向固定夹紧在该径向肩上。
摘要（英）：

A gas probe for determining physical property of gas, particularly temperature or gas mixture thereof, such as the concentration of gas composition of engine exhaust gas is provided, which comprises a tubular housing and a sensing element 11, the end section 111 of a gas side and the end section 112 of a connecting side thereof protrude from the housing and the sensing element is sealed between end sections 111, 112 relative to the housing. In order to expose the end section 112 relative to the end section 111 of the gas, simply and reliably seal and reduce the axial structural height of the whole probe, a ring flange 13 is supported by the sensing element, arranged in the area between end sections 111, 112 and connected with the in airtight sensing element. An annular radial shoulder 123is constructed in the housing, the ring flange is axially clamped on the radial shoulder by a seal ring 14 mounted between the radial shoulder and the ring flange.
