Pressure sensing device |
摘要 |
A compact sensing device is provided which the tension applied to the sensing member is substantially uniform and free of thermally changing. Either the sensing member itself or a clamping member disposed around the device or both, are made of a precipitation hardenable metal which will contract during a heat treatment. If the sensing member is thermally contracted a uniform radial tension will result, and if the clamping member is contracted a uniform clamping force applied to the device for tensioning the diaphragm will be provided without the necessity of clamping bolts.
