A wide range pressure sensor is designed based on the theoretical basis of LC series resonance circuit model to realize the wireless passive measurement in the harsh environment, such as high temperature and high pressure. The capacitive pressure sensitive device is devised by the technology of high-temperature co-fired ceramics (HTCC) to form nine density cavities in zirconia ceramic substrates, and thick film technology to print capacitance plates and planar spiral inductors. The theoretical calculation and simulation analysis of the designed sensor are made respectively under high pressure (10MPa) and temperature (600 °C), the results of which verify the feasibility of the design in a wide range of pressure for high-temperature applications, and provide the reliable theory basis for the fabrication of wide range pressure sensor.

A novel reentrant cavity-microstrip patch antenna integrated wireless passive pressure sensor was proposed in this paper for high temperature applications. The reentrant cavity was analyzed from aspects of distributed model and equivalent lumped circuit model, on the basis of which an optimal sensor structure integrated with a rectangular microstrip patch antenna was proposed to better transmit/receive wireless signals. In this paper, the proposed sensor was fabricated with high temperature resistant alumina ceramic and silver metalization with weld sealing, and it was measured in a hermetic metal tank with nitrogen pressure loading. It was verified that the sensor was highly sensitive, keeping stable performance up to 300 kPa with an average sensitivity of 981.8 kHz/kPa at temperature 25°C, while, for high temperature measurement, the sensor can operate properly under pressure of 60–120 kPa in the temperature range of 25–300°C with maximum pressure sensitivity of 179.2 kHz/kPa. In practical application, the proposed sensor is used in a method called table lookup with a maximum error of 5.78%.
