为了满足深井和核电站强震动观测需求,研制一种能保证在100℃—130℃环境下有效连续工作的力平衡反馈加速度计,并重新设计其电路方案,主要利用高温分立元件重新设计检波及前后级放大电路,并对其余电路进行升级改造。样机实验结果表明:设计方案满足要求,具有一定的实用性。
In order to make the Force Balance Accelerometer can work properly in 100—130℃, we redesign the electronic part of Accelerometer. We change the structure of the circuit and implement the Detection and Amplifier circuit with discrete components which can work in high temperature. After testing, the result illustrates that this new prototype can work in the temperature range 20—130℃.
