摘要

PROBLEM TO BE SOLVED: To provide a Bourdon tube pressure gauge which irradiates a scale part of a dial face with light from a light source evenly and uniformly, can prevent a Bourdon tube from being frozen, allows the light source to be easily installed, and can be made compact and light.SOLUTION: A Bourdon tube pressure gauge comprises: an arcuate Bourdon tube 1 into which a fluid flows; a pointer drive mechanism 3 making a pointer 2 rotate according to displacement of the Bourdon tube 1 caused by change in pressure of the fluid flowing into the Bourdon tube 1; a dial face 5 arranged on the front side of the Bourdon tube 1 and provided with a translucent scale part 4 in a circular arc shape; and a light source 6 illuminating the dial face 5 from the rear side. The light source 6 is configured by a tape-like LED module 21 provided with a plurality of LEDs 20, and the tape-like LED module 21 is arranged in the vicinity of the Bourdon tube 1 and along the Bourdon tube 1.
