Low cost, precision 4...20mA loop powered display
Submitted by: Eissa Rahmani (Rahmani.kcc@gmail.com).
An electronic circuit that I designed. it is based on a low cost 7106 (31/2 digit A/D). it works without any external supply and drops only 4.5V from 4...20mA of loop supply. I will glad to send you all information about this circuit if you found it useful
