4 to 20 mA Transmitter Circuit Operation - Instrumentation Tools

Learn how a 4 to 20 mA transmitter circuit operation using a basic animation circuit.
In this video, we learn how a transmitter controls the 4 - 20 mA output loop current based on the measured process variable from the input sensor circuit.

Can I ask what transistor model did you use on actual setup

[@tonysafepower1453]

Excellent teaching

[@michaelcostello6991]

What does it mean the loop power is 20 mAmp. How can it be different from the 4 to 20MAmp. There is just 2 wires. Can anyone explain that, Thanks

[@buttholesurfer2000]

surely this design is beta dependant

[@guventan7574]

It is not linear

[@embeddedexplorer]

Which transistor is use here?

[@balu2005]

Npn

[@jasonamosco318]

@@balu2005 Micromotion means what model? Is BC547? 2N2222? Or etc?

Is not a good circuit, don't use this one.
