As the intensity of light varies - by the breaking of a light beam, say, or a decrease in general illumination - the amount of current generated by the sensor changes.
光线强度的变化(如光束被遮断或是一般照明的降低)会造成侦测器里产生的电流随著改变。
Being used as a current direction sensor, this compass is suitable for all kinds of current meters required by measuring direction.
此种罗盘可用于各种海流计上作为测向传感器，也可用于其他需测方位角的仪器上。
A Rogowski coil and a capacitive voltage divider are used as current sensor and voltage sensor respectively in the transducer and optic fibers are used to transmit signal.
该互感器以罗柯夫斯基线圈作为电流传感元件，以电容分压器作为电压传感元件，以光纤作为信号传输通道，借助有源电子调制和信号处理技术实现电流、电压的测量。
