PRESSURE SENSOR |
| 摘要 |
A pressure sensor includes a tubular housing; a diaphragm which is joined to one end portion of the housing through a fusion zone; and a sensor element which is disposed in the housing and to which pressure received by the diaphragm is transmitted. As viewed in a section which contains the center axis of the housing, a pair of the fusion zones exist, and each of the fusion zones is formed in such an inclined manner that its distance from the center axis increases as it extends from the outer surface of the diaphragm toward the other-end-portion side of the housing. |

1. A pressure sensor comprising:
a tubular housing having a forward portion and a rear side; a diaphragm joined to the forward portion of the housing through a fusion zone; and a sensor element disposed in the housing and to which pressure received by the diaphragm is transmitted, wherein as viewed in a section which contains a center axis of the housing, the fusion zone has a pair of cross-sectional portions, each of the cross-sectional portions formed in an inclined manner such that a distance from the center axis to a respective cross-sectional portion increases as the cross-sectional portion extends from an outer surface of the diaphragm toward the rear side of the housing. |
