Suppose there is DP transmittrr... They diff pressure deflects a diaphragm cell which forms ccapcitor.. and further is this is a part of oscillator which varies its frequency on diff pressure change. This change in freq is converted in voltage variation then further this varying voltage is converted into current with an op amp current controller. Which regulates 4-20 mA
@@srikanth0282 Practically I never faced distance issue. Theoritically it is infinte as current remains same in series formed by power source, AI I/O channel and transmitter.
Super thanks your explanation 🙏🙏
Very good explanation Sir, thank you for sharing.
Very nice, thanks sir 🙏
Tqs for this good knowledgeable video and i would like to know about the exact conversation of 4- 20 ma in transmitter.

Sir, what is the maximum distance for 4 to 20mA signal?

Do you have a training school l wanted to study plc
No .. you can discuss we will learn together
