| 摘要 |
A dual output accelerometer having first and second output channels, comprises a supporting base, a first transducer comprising a plurality of inter-connected first piezoelectric elements, a second transducer comprising a plurality of inter-connected second piezoelectric elements and a seismic mass. Each of the first piezoelectric elements and the second piezoelectric elements are interleaved with one another, and are co-located with the seismic mass, the co-located first and second piezoelectric elements and the seismic mass being fastened to the supporting base by a rigid mechanical coupling. The interleaved first and second piezoelectric elements provide an improved first output channel to second output channel matching. |
