Principle of I to P Converter/transducer
Basic Instrumentation - Basic I to P Converter

 

The electronic part module receives standard DC current input signal (4-20 mA) from DCS or PLC. This current will operate coils then increasing or decreasing the magnet force following the input signal.

Magnet force will drive the linkage to adjust the distance between flapper and nozzel or in other word to control bleed air through an integral flapper-nozzel arrangement. The nozzle pressure provides the input signal to operate the relay. Then relay output pressure is applied directly to the final control element (control valve or actuator auto choke valve).
When the flapper moves away from the nozzel, the output pressure will low/falls, and inversely when the flapper come closer to the nozzle the output pressure will increase/high.
