| Abstract: | The theory and structure of the opt-electronic pressure measuring and transferring system are introduced, which has been used in measuring static pressure of the rotating centrifugal fan successfully. In the mechanism, two micro-processers, which can store and send signal digitally, are installed in rotating system and static system respectively. In the system, the Duel-sending-calibrating system and Returning-calibrating system can ensure correct transferring of the signal. |
