Prime RBS fiber optic sensor (left), currently under development, is being designed for high temperature propulsion system applications and will be significantly lower cost that competing high temperature pressure sensor technologies. The results from an FEA analysis of the probe tip (right) shows how deflection of the media isolating diaphragm generates a strain on the monolithically integrated resonant beam.

High Temperature Pressure and Temperature Sensors

Prime is currently developing the next generation of high temperature pressure and temperature sensors which show significant promise in providing dynamic pressure measurements and highly accurate temperature measurements in the most demanding applications up to 3000F. Prime’s all optical Resonant Beam Sensor (RBS) technology combines the advantages of currently available fiber optic pressure and temperature sensors with the proven reliability of mechanical resonator-based electrical sensors.  Low-cost interrogation/signal conditioners will allow Prime’s RBS sensor technology to be applied in a wide range of industrial and aerospace applications.
