Optically Coupled Resonant Pressure Sensor

RPIC Systems proposes to develop a compact, optically coupled precision MEMS-based resonant high-pressure transducer that provides primary national standards from 280 MPa to 500 MPa, having 300¿C), the capability of oil or gas fill, and characteristics of quartz resonant gauges at lower pressures. The proposed sensor of RPIC Systems also will address the need of industrial and commercial markets for precision, high-pressure sensors having low hysteresis, electromagnetic interference (EMI) immunity, and increased safety in harsh, volatile, or explosive environments. COMMERCIAL APPLICATIONS: Optically-coupled high-accuracy resonant pressure sensors for high-pressure measurements to 500 MPa have potential applications in numerous military, aeronautic, automotive, gas/oil, down-hole drilling, and high-end consumer products. Segments of the pressure sensor market such as military, aerospace, commercial avionics, process control, and industrial automation are increasing demand for more compact, accurate and reliable solutions for harsh, volatile, and explosive environments. The integration of digital communications, and internetworking within sensor systems is expanding the number of potential applications and capabilities of optically coupled pressure sensors.
