Editor’s note: This month we are pleased to have Colin Wells from Texas Instruments as our blogger. In modern industrial control systems, 4-20 mA current-loop transmitters remain one of the most ...
To complement the 2-wire and 3-wire sensor transmitter blogs that Kevin Duke and I have already published on Precision Hub, my next few blog topics will be on 4-wire sensor transmitters. The blogs ...
Use of 4-to-20-mA current loops involves more than just a simple series connection between sensor, display, and power supply. The point where a sensor takes a measurement is, at times, many yards away ...
