PRESSURE SENSOR DIAPHRAGM |
| 摘要 |
A pressure sensor includes a pre-formed diaphragm located at the distal end of a pressure sensor. The diaphragm has a convex surface on a first side of the diaphragm which is exposed to a fluid to be measured. A strain gauge is attached to a second surface on the opposite side of the diaphragm. The diaphragm may be deformed to have the convex curvature on the first surface, and heat treated. |

1. A method of manufacturing a pressure sensor diaphragm having a first surface on a first side of the diaphragm, and a second surface on a second, opposite side of the diaphragm, the method comprising:
deforming the diaphragm such that the first surface has a convex curvature and the second surface has a concave curvature; and attaching a strain gauge to the second surface of the diaphragm. |
