| Abstract: | The high precision measure frequency is a key in SAW pressure sensors, because the output of SAW pressure sensors is frequency. There are many ways to measure frequency, but no way to adapt the SAW pressure sensors used in industrial field. Principle of high quality measure frequency for SAW pressure sensors is given, which is based on the analyzing currently method of measure frequency. And the system structure of measure frequency and electronic element are presented. |
