This reference design shows how to develop a high-performance, high-voltage 2- or 3-wire 4–20mA current-loop transmitter suitable for industrial process control and ...

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 ...

Galvanically (that is, optically or electromagnetically) isolated 4- to 20-mA current loops offer robust noise immunity and tolerate long cable runs. These advantages, combined with simple unshielded ...

What’s the difference between a transmitter and a sensor? Nine different types of sensor transmitters. How does each type of transmitter work? What are the components of each transmitter type? Sensors ...

In the first three installments of this series, we discussed whether or not an old transmitter was even worth fixing, followed by some techniques I ve used to repair high-voltage power supplies, ...
