| 发明名称 | Pressure sensing device and method for using the same | ||
| 摘要 | A pressure-sensing device is for use in an underground well. The pressure-sensing device includes a pressure sensor arranged at least to sense whether a pressure in the well is below or above a given limit value, and a signal generator arranged to generate an acoustic signal in a well body in the well in response to a sensed pressure from the pressure sensor exceeding said limit value. A method is for measuring pressure in an underground well. A use of a pressure-sensing device is to monitor the pressure between two spaced-apart barrier elements in an underground well. | ||

| 主权项 | 1. A pressure-sensing device for use in an underground well, the pressure-sensing device including: a pressure sensor arranged at least to sense whether a pressure in the well is below or above a given limit value; a signal generator, in the form of a percussion device, arranged to generate an acoustic signal in a well body in the well in response to a sensed pressure from the pressure sensor exceeding said limit value; and a negative-pressure chamber in which the percussion device is positioned, wherein the pressure sensor is a mechanical pressure sensor arranged to break when the sensed pressure exceeds said limit value; and wherein the pressure-sensing device further includes a piston arranged to be released when the mechanical pressure sensor breaks and be driven by a pressure difference between the well and the negative-pressure chamber so that the percussion device will generate the acoustic signal in the well body. | ||
