High temperature sensor for engine compartment of motor vehicle, has ceramic insulating sheath comprising cylindrical outer covering with portion forming support surface that cooperates with associated plane surface of mounting bracket

摘要

The sensor has two electric wires (9) each with an end connected to a thermistor e.g. positive temperature coefficient thermistor, for transferring an abundant temperature signal from the thermistor to a processing unit. A ceramic insulating sheath (10) has a cylindrical outer covering (19) and an associated maintaining channel (17) for each electrical wire. A portion of the covering forms a support surface (21) that cooperates with an associated plane surface (23) of a mounting bracket (25).
