BD series electric transducer is a kind of device which can isolate and transmit electric parameters such as current,voltage frequency, power, power factor or temperature, resistance and so on non-electrical parameters, into linear DC analog signal or digital signal. They can directly connect with the pointer table, digital meters, also can connected with automatic control devices (eg PLC), a variety of A / D converter, and the computer system.
