A method of reduce zeroshift of piezoelectric accelerometers 减小压电式加速度计零漂的一种方法
2.
The combined motor vibration sensor which is held manually with double charge amplifier placed inside and with frequency compensating circuit is designed based on the existed press - electricity accelerator of vibration and the measuring vibration system of charge amplifier in the paper 本文在现有振动压电式加速度计、电荷放大器测振系统的基础上,设计了手持式内置微型双电荷放大器和频率补偿电路的一体化发动机振动传感器。
