Technical Field

[0001] This invention relates to the field of improvement technology for pressure meter equipment, specifically to a detection method for a solid-liquid hybrid magnetic dynamic pressure meter device. Background Technology

[0002] Existing pressuremeter measurements have certain limitations. The characteristics of the detection area directly affect the measurement results, and existing measurement methods can cause disturbances to the detection area, thus affecting the accuracy of the instrument's measurement results. Commercially available pressuremeters use injected oil and nitrogen to pressurize and achieve the measurement purpose. However, this measurement method can cause air and oil leakage after the pressuremeter's bladder ruptures, leading to measurement failure and, in severe cases, even personal injury. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a detection method for a solid-liquid hybrid magnetic pressure meter device, thereby improving the accuracy of the measurement results of the pressure meter and effectively avoiding measurement failures and personnel injuries caused by the rupture of the pressure meter bladder.

The pressure detection device and magnetometer transmit the detected pressure data and magnetic field strength data of the outer wall of the pressure gauge to the control computer for data recording and analysis.
