模数转换装置为非电量转换，光导纤维对把该信息远距离传送给数字显示仪表，它能用数字量连续显示液位的变化。
Analog—to—digital converter is non—electrical transform. A pair of optical fibres can transmit signal to digital instrument to a great distance away.
该装置的主要特点是不必使用任何数字仪表和电量变送器，各电量的测试是采用离散采样、数据处理的方式来实现。
With sampling the required data point by point without any digital meters and parameter transducers the computer finds various values of current, voltage and power by data processing.
系统采用精确的仪表作为电量测试单元，配备霍尔传感器，适用于各种变频器电源供电状态下的电量测量。
This system that adopts precision instrument as test units of electricity quantity, and equips with Hall sensor is used for electricity quantity test of various transducer power in power supply state.
