High temperature sensor, especially for measuring the temperature of recirculating exhaust gas in a motor vehicle engine, has a simple design using a high temperature sealant to enable standard sensor machining to be used

摘要

Temperature sensor comprises a pipe section (3) and a connection section (2) joined together as a single unit. The contact socket (5) has a diameter that is considerably smaller than the contact socket retainer (4). A high temperature sealant (6) is used to fill the resultant annular space. The sealant used is an inorganic, non-conducting thermo-plastic.
