旧式舰用蓄电池的内部溶液密度测量传感系统是采用弹簧固定的，装置受船体的加速度的影响很大，常常不能正确地反应蓄电池内硫酸溶液的密度变化而给出信号，误差很大．作者对悬浮式的传感方式作出理论上的论证，并分析了传感器浮出液面的体积为浸入溶液中的体积多少倍的情况下加速度的影响最小． The old marine battery internal solution density measurement sensing system is fixed by a spring, the device affected by the acceleration of the hull is very large, often can not correctly reflect the battery density of sulfuric acid solution changes give a signal error is very large. The author makes a theoretical demonstration of the sensing method of suspension and analyzes the influence of the acceleration on the sensor when the volume of the floating surface is smaller than the volume immersed in the solution.
