Abstract

We present a novel dual-diaphragm-based, integrated pressure and temperature sensor design for aerospace applications that require accurate, durable, and temperature-compensated pressure sensors. We discuss potential improvement in the sensor's high-temperature capabilities, and demonstrate significant increases in signal-to-noise performance and accuracy, resulting from the dual-diaphragm design. We also describe an integrated optoelectronic transceiver design, employing a dual-wavelength error compensation approach, for pressure and temperature sensing. Other issues leading to practical sensor systems are also discussed.
