Type EAA-550 series I/P,E/P transducer(Electro-pneumatic transducer,I/P,E/P converter) is an electronic pressure regulator that converts a variable signal (current or voltage) to a proportional pneumatic output.

The method of electro pneumatic conversion is to convert an electro 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.

Requirements for the use of electro pneumatic converters

The electro pneumatic converter is a conversion instrument that can convert 4-20mA into a 20-100KPa pneumatic signal. It should be used according to the site conditions, that is, the spring compression coefficient of the pneumatic control valve connected to the electro converter is 20-100KPa, If it is used beyond this range, the full-open and full-close actions of the regulating valve cannot be realized. This is different from the valve positioner, and the electro converter must be carefully selected.
