What is a Loop Powered Panel Meter?

A loop powered panel meter is a device used for measuring and displaying process variables, such as temperature or pressure, in industrial applications. It is powered by the current loop signal (typically 4-20 mA) that carries both the measurement information and the power required for the panel meter's operation. This eliminates the need for a separate power supply for the panel meter, simplifying installation and reducing wiring complexity.
