Title:
PRESSURE SENSOR
Document Type and Number:
WIPO Patent Application WO/2019/093054
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a pressure sensor (100) with which it is possible to improve workability, a sealing adhesive (136) being used therein in order to enhance water-proofing properties and air-tightness without using an atmosphere-side O-ring or packing, and the direction for sealing the sealing adhesive (136) furthermore being set to one direction. A pressure sensor (100), wherein a protective cover is configured from a combination of any of a joint (111), a lower cover (112), a pressure detector (120), and a case (135). The protective cover has a side wall forming an outer periphery and a bottom part at a pressure-chamber side of the side wall, and a sealing adhesive (136) is sealed in an opening (135A) on a side of the protective cover that faces the bottom part, and maintains the water-proofing properties and air-tightness of a signal transmission unit (130).
