Hi I am interested to a circuit that is a 4mA-20mA current loop temperature sensor but
I don't understand how the circuit is working.
Here is the circuit:
Circuit - TEMPERATURE SENSOR WITH 4 TO 20mA CURRENT LOOP - Circuits designed by David A. Johnson, P.E.
How is it working? And more precisely what is the use of the schottky diodes? How the part with the temperature sensor and the shunt voltage reference is working?
thanks alot,
Jenifer
