Temperature measuring device for detecting temperature of fluid medium, for use in motor car, has turbulator arranged in housing, which is provided for generating swirl with swirl axle parallel to flow direction of fluid medium

摘要

The temperature measuring device (110) has a temperature sensor (116) for detecting temperature of fluid medium (112), which is accommodated in the housing (118). The turbulator (124) arranged in housing is provided for generating swirl with swirl axle parallel to the flow direction (122) of the fluid medium. The turbulator is provided with hole whose diameter is set in the range of 0.5-2 mm. The temperature sensor is provided with temperature measuring resistor such as negative temperature coefficient (NTC) resistor.
