The role of electro pneumatic converter

Pneumatic control valve is a kind of pneumatic instrument, this instrument receives pneumatic signal to act, and is not in touch with the electrical signal in our industrial control. Therefore, the control of the industrial field needs a conversion instrument to convert the electrical signal from the control room into regulation. The gas signal that the valve can recognize. This kind of conversion instrument is installed on the on-site pneumatic control valve, receives the electrical signal from the control room and then converts it into the corresponding standard pneumatic signal, and enters the control valve as the pneumatic energy source that the control valve can operate.

Electromagnetic becomes spatial change The method of electro pneumatic transducer is to convert an electrical signal into a physical displacement of a mechanical part through electromagnetic conversion. This mechanical part is also the baffle part in the nozzle baffle mechanism. The baffle is a solid thin metal disk in the middle. The other side of the disk is designed as a thin metal coil structure with a convex outside and a hollow inside. The metal coil passes through a strong magnetic permanent magnet cylinder.

The current in the coil is a 4-20mA current control signal from the control room. With the different current values of the energized coil, the strong magnet's attraction is different, causing a physical displacement of the disc baffle integrated with the metal coil.
