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 ...

Explore two effective methods for finding the magnetic field of a current-carrying wire loop. This short explains the reasoning behind each approach and shows how they connect theory with practical ...

Two-wire transmitter technology came about from an agreement among various instrument suppliers in the 1950s to standardize on 4-20 mA current loops as a means of sending a flow, temperature, pressure ...

Visualize how magnetic field strength changes with distance from a current-carrying wire loop. This short uses clear graphs and physical intuition to show key trends, helping you better understand ...
