Temperature sensor for heat engine of motor vehicle, has thin stainless steel casing with mouth integrated to body, and two bases having cap containing thermistor that provides temperature signal

摘要

The sensor has two plugs, where each plug has an end emerging inside a casing (2) and another end connected to a processing apparatus of temperature signal provided by a negative temperature coefficient thermistor (3). The casing (2) is a thin stainless steel sheet having thermal conductivity less than or equal to 50 watt per meter Kelvin and has a mouth (20) integrated to a body (1). Two bases have a cap containing the thermistor. An independent claim is also included for a device for mounting a temperature sensor in an opening of a wall of a conduit.
