Series
KGD5 Mine-used Electric Quantity Transducers include Model KGD5A
Power Network Voltage Transducer and Model KGD5B Load Current
Transducer. They can detect the electric parameters of the power
supply loop in real time and output Intrinsic Safety signal. When used in
coal mine underground with a danger of methane and coal dust
explosion, they must be installed inside the flameproof box. The series transducer has the
advantages of small size, low power consumption, high accuracy
and wide frequency response and is a perfect electric quantity
detecting sensor for computer remote operating device, power
dispatching system and automatic control equipment.
