Embodiment Construction
[0036] Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0037] figure 1 It is a longitudinal sectional view showing a liquid-sealed pressure sensor 100 as an example of the pressure sensor of the present invention.
[0038] figure 1 Among them, the liquid-sealed pressure sensor 100 includes: a fluid introduction part 110 for supplying a fluid to be pressure detected to a pressure chamber 112A described later; a pressure detection part 120 for detecting the pressure of the fluid in the pressure chamber 112A; The signal sending part 130 of the pressure signal detected by the pressure detecting part 120 ; and the outer surface member 140 covering the fluid introducing part 110 , the pressure detecting part 120 and the signal sending part 130 .
[0039] The fluid introduction part 110 includes: a metal joint member 111 connected to a pipe that guides a fluid to be pressure detected; Shaped metal bottom plate 112.
