| 摘 要： | 在振动与冲击测试中,ICP加速度传感器应用较为广泛,而传感器灵敏度是其最基本的指标之一。实际使用时,ICP加速度传感器通常都会配有信号调节仪,该调节仪为ICP加速度传感器提供恒定电流,不同的信号调节仪所提供的恒定电流也会有所不同。在不同恒定电流情况下,传感器灵敏度是否随之变化,如何变化？针对这一问题我们展开讨论。

| Abstract: | The ICP accelerometer sensor is widely used in the vibration and shock test,and the sensitivity of the sensor is one of the most basic parameters.During testing,the ICP accelerometer sensors are usually equipped with a signal adjusting instrument.The signal adjusting instrument provides a constant current for the sensor.The constant currents provided by different signal adjusting instruments would differ.Whether the sensor sensitivity changeds with the current and how it changes are discussed in this paper. |
