Title:
PRESSURE SENSOR
Document Type and Number:
WIPO Patent Application WO/2020/197168
Kind Code:
A1
Abstract:
The present invention relates to a pressure sensor. The pressure sensor of the present invention has a main body housing (10) and a cover housing (30). The main body housing (10) has an inner space (16) and a substrate (28) having a sensing element (29) is provided in the inner space (16). The cover housing (30) has a seal (41) integrally formed therein so as to encompass the edge of the upper surface and the side surfaces of the sensing element (29) so that the sensing element communicates with a communicating passage (33) but does not communicate with the inner space (16) in which the sensing element (29) is provided. The communicating passage (33) is formed in a straight line so as to allow fluid to flow to the sensing element (29) without curving. A discharge path (36) is formed on one side of the communicating passage (33) so as to communicate therewith, and thus the inside of a tube communicating with the communicating passage (33) is maintained at atmospheric pressure at all times. An inflow orifice (34) is in the downstream side of the communicating passage (33) and a discharge orifice (37) is in the downstream side of the discharge path (36) so that the flow of the fluid is rapid.
