A miniature directional indication sensor system capable of operating at elevated temperature. A directional indication sensor system is less than 1 inch in diameter and 7 inches in length. The directional sensor system provides angle measurement in applications from which current larger directional sensors are barred. The present invention provides increased shock and vibration resistance. The chassis of the present invention has an high resonant frequency, or "Q". The present invention is implemented with power supply, sensor drive and sense circuits in thick film or multi-chip module electronic assemblies. The thick film or multi-chip module electronics assemblies also contribute to the increased shock and vibration resistance. Sensor drive and sense functions may be implemented in one or more application specific integrated circuits and integrated with multi-chip module electronics assembly. Analog-to-digital conversion of sensor signals is implemented in a voltage-to-frequency converter circuit provided by the present invention. Furthermore, the present invention eliminates data lag between channels by providing simultaneous sampling of all the sensor channels. |
