DBJY Amp Chart Recorder is a kind of essential instruments to monitor and record the operating status of the submersible pumping unit for oil production and other type power supply systems. It functions by receiving a *5A signal from the current transformer in the control system of the pumping Units. In-door and Out-door designs are available for option.

 

Operation Principle

DBJY Amp Chart Recorder operates with **5A AC current by AC current transformer as signal, which will be applied to the both terminals of the primary coil on the transformer installed inside. When the current varies from 0 to 5A gradually, its secondary coil will induct and take the corresponding value. After the filtering process, it produces a variable DC current ****0mA applied to on the deflection coil of the returning mechanism. The deflection coil will drive the recording pen through mechanism and the specific magnetic field of the returning unit for the corresponding records.

 

Mechanics

DBJY series recorders consist of returning mechanism, chart driving system, Transformer and accessory components, which is easy to be repaired and maintained
