TRASDUTTORE DI FORZA A CRISTALLO FATTO RISUONARE CONTEMPORANEAMENTE IN PIU MODI |
摘要 |
<p>The invention is a single crystal force transducer in which the crystal is simultaneously resonated in two different modes having substantially the same frequency-temperature characteristics and different frequency-force characteristics. The difference in the change between the two resonant frequencies with a force applied to the crystal is therefore a temperature compensated signal indicative of the applied force. In the preferred embodiment the two resonant modes are anharmonic modes having a plurality of antinodes angularly disposed to each other.</p> |
