Title:
PRESSURE SENSOR
Document Type and Number:
WIPO Patent Application WO/2019/028945
Kind Code:
A1
Abstract:
A pressure sensor, comprising: a displacement sensor (40), an elbow pipe (30) and a base (32); a first end of the elbow pipe (30) is fixed on the base (32), the displacement sensor (40) comprises a first reflection member (50) and a second reflection member (51), the first reflection member (50) being fixed in the main body of the displacement sensor (40), and the second reflection member (51) being movable relative to the main body of the displacement sensor (40); the main body of the displacement sensor (40) is fixed on the base (32), and the second reflection member (51) is connected to the elbow pipe (30) at a first position of the elbow pipe (30); alternatively, the second reflection member (51) is fixed on the base (32), and the main body of the displacement sensor (40) is connected to the elbow pipe (30) at a first position of the elbow pipe (30); when the pressure in the elbow pipe (30) changes, the elbow pipe (30) deforms, such that the distance between the first reflection member (50) and the second reflection member (51) changes, and the magnitude of the change of pressure is obtained by means of the displacement measured by the displacement sensor (40).
