WIPO Patent Application WO/2016/052710

Kind Code:

A1

Abstract:

Provided is a sensor device of which a body with a spiral passageway formed therein can be inexpensively fabricated. The sensor device 1 is provided with: a body 10 with a gas passageway 13 formed therein into which vapor to be detected flows; and a pressure sensor 30 mounted to the body 10 in communication with the gas passageway 13 so as to detect vapor pressure in the gas passageway 13. The body 10 includes a bar-shaped portion 11 having a columnar inner peripheral surface 11b. The sensor device 1 is provided with a sheath pipe 21 (inserted body) formed in bar shape with spiral grooves 23 formed in an outer peripheral surface 22, the sheath pipe inserted in the bar-shaped portion 11 of the body 10 and forming a spiral gas passageway 13 (spiral passageway 14) between the inner peripheral surface 11b of the bar-shaped portion 11 and the spiral grooves 23.
