圧力検出装置
Document Type and Number:
Japanese Patent JP7016310
Kind Code:
B2
Abstract:
To provide a pressure detector with which superimposition of noise from the outside is suppressed.SOLUTION: Provided is a pressure detector 20 comprising: a pressure detection unit 41 for detecting a change of a pressure; a first housing 49 having conductivity, for accommodating the pressure detection unit 41 inside; and a second housing 311 for accommodating the first housing 49 inside and provided with a pressure receiving unit 32 for receiving a pressure from the outside and having conductivity. The first housing 49 and the second housing 311 are fixed via an insulating member 49a arranged between the first housing 49 and the second housing 311 and are electrically insulated by an air gap separating the first housing 49 and the second housing 311 from each other, with an insulating coating 49a formed on an outer surface of the first housing 49 and/or an inner surface of the second housing 311 facing each other across the air gap.SELECTED DRAWING: Figure 3
