Loop-powered transmitters have progressed from purely analog signal conditioners to highly flexible smart transmitters, but the chosen design approach still depends on a system’s performance, ...

IoT connectivity is a hot topic, but it’s not a new idea, except for the “Internet” aspect. Industrial and some commercial applications have been connecting all sorts of sensors and transducers 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 ...

Significant efficiency and performance improvements can be realized by improving the current loop’s power supplies, replacing linear regulators with high-efficiency buck regulators. It also increases ...

As more and more refrigeration systems incorporate electronic controls into their design, it is becoming increasingly important for technicians to be able to troubleshoot these electronic devices. One ...
