| Abstract: | The pressure sensor was used to measure the high and low temperature environment of high pressure gas absolute pressure, the sensor used a resonant cylinder sensor, digital output works. Range was to meet the 0.02-4.0 MPa, accuracy ,was better than ±0.05% FS, it could be -55-150℃ in a wide temperature range reliably. The sensor can be used in the aircraft engine power transfer systems, measuring the pressure of the engine at different positions. The design method of the resonant cylinder was discussed to determine the accuracy of the wide temperature high-pressure structural parameters of resonant cylinder. |
