Hlo Friends 🙏
Welcome to Industrial E&I Engineering
Aaj ke es video maine I/P CONVERTER ke bare me bataya hu ki kaise kam karta hai or eska use instrumentation me kaha hota hai.
IP Converter Working Principle
I/P Converters operate on a similar principle as proportional valves in that they provide adjustable flow volumes and control functions. In converting electric current into pneumatic output, I/P converters also eliminate a need for an external power supply to control the pneumatic operated components. In doing so, I/P converters increase machine efficiency and control.
The function of I/P converters relates to the concept of an electromagnetic force balance principle, i.e., the process of converting electric current into force and then pressure. Simply, for I/P converters to work, electromagnetic effects are exploited to build current which force transducers for mechanical actuation. This action converts electrical current (typically 4 to 20 mA) into pneumatic pressure output (3 to 15 psi) that, in turn, proportionally controls the opening or closing of a valve according to the force balance principle.
As I/P converters operate, they deliver proportional downstream flow of pressure related to the rate of electrical current that is received into the transducer’s electrical circuit. In web tension control systems, I/P converters serve as an important connecting interface between the controller and pneumatic brakes and clutches.
