Document Type and Number:
WIPO Patent Application WO/2020/017198
Kind Code:
A1
Abstract:
This pressure/temperature sensor includes a sensor part (150) having a pressure detection unit (152) that detects the pressure of a medium to be measured and a temperature detection unit (152) that detects the temperature of the medium. The pressure/temperature sensor includes holding parts (110, 120, 130) each of which has a tube part (113) and holds the sensor part so that the sensor part is positioned inside the tube part and in which the tube part is fixed to piping (200) to which the tube part is to be attached. The pressure/temperature sensor includes an introduction part (170) that is provided to the holding part so as to be positioned more inside the piping than the sensor part and that is positioned inside the piping through fixing of the tube part to the piping. The introduction part includes a plurality of blades (175) that have blade surfaces (174) parallel to the projection direction of the introduction part with respect to the sensor part. The blades are radially arranged on a perpendicular surface perpendicular to the projection direction, and angles formed between the blade surfaces of adjacent blades are all acute.
