Loop-Powered:

• Power Source: The device operates on power drawn directly from the current loop, typically a 4-20 mA loop, which is commonly used in process control industries for transmitting sensor signals.
• Simplified Wiring: Since it's powered by the loop, there is no need for an additional power source, simplifying installation and reducing wiring complexity.

LED Universal Indicator:

• Display Type: The indicator uses LEDs  to provide a visual readout of the measured parameter, such as temperature, pressure, flow, or other process variables.
• Universal: The term "universal" usually indicates that the device can be programmed or configured to display a wide range of parameters or accept various input types.
