The amplifier having reason structure, precisely and conveniently controlled gain, high insulating resistance, low noise and wide gain flatness range has been proved in the working of the impulse vibration specimen material level detection device. 通过在冲击振动料位计中的使用,证明该方案的程控增益隔离放大器结构合理,增益控制准确、方便,隔离电阻高,噪声低,频带平坦。
Because the effect in seperation of signal and noise of vibration is good, identification of in cylinder pressure is accurate. It provided the effective method for real time condition detection and early stage fault diagnosis of internal combustion engines. 由于振动信号信噪分离效果好,从而提高了缸内气体压力的识别精度,为内燃机工作状态的实时监测和故障早期预报提拱了行之有效的方法。
The inductive wear particle detection sensor is too sensitive to be interfered by noise and vibration environment, the inductive signal of the metal grains are often flooded by the noise and interference, which seriously affects the detection results of the inductive wear particle detection sensor. 由于电感式磨粒检测传感器对环境的噪声与振动的干扰很敏感,金属磨粒引起的感应信号容易被噪声与干扰所淹没。
