Abstract
A pressure sensor and a method of measuring pressure with the pressure sensor, based on measuring the effect of pressure loads on the acoustic resonance mode frequencies of a spherical core (e.g., a hollow sphere). The pressure sensor includes a transmitter configured to transmit vibrational signals to a sphere, and a receiver on the opposite side of the spherical core that is configured to receive vibrational signals from the spherical core. According to the method of measuring pressure with this sensor, the spherical core exhibits a pressure-dependent resonance response that can be monitored utilizing a frequency response technique. Peak shifts observed under an unknown pressure load can be compared to a calibration of the spherical core under a series of known pressure loads to thereby determine the unknown pressure. The pressure sensor and method may be operated in real-time at very high temperatures and pressure, and may be used in borehole applications and in aggressive media.
