“地回路”是振动测量系统中最常见的一种误差源,由于传感器与信号适调器之间的公共回路或屏蔽回路流过的“地”电流而产生了虚假的和不需要的信号,且干扰了真正的振动信号。这些地电流是由于多个不同 Ground loops are the most common source of error in vibration measurement systems and produce spurious and unwanted signals due to “ground” currents flowing through the common loop or shield loop between the sensor and the signal conditioner, And interfere with the real vibration signal. These ground currents are due to a number of differences
