Recently, I’ve been working on a solar off-grid monitoring system. In the system are a few split-core Hall effect sensors to monitor DC current in the solar panel current, the battery charge current, ...

Industrial temperature sensors are widely used with 4–20mA current-loop transmitters in industrial control and automation. In the current loop the temperature sensor converts a temperature into a ...

Many industrial and control applications use analog current loops as the physical link for measurements and actuator control. Although several ranges are used, the most popular is still the 4- to ...

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 ...

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 ...
