The Rosemount 751AM7NABC Field Signal Indicator is a rugged and reliable device designed to provide a local, easy-to-read display of a 4-20 mA process variable. It connects directly in series with the 4-20 mA loop, requiring no separate power supply, which simplifies installation and reduces wiring costs. Housed in a durable, low-copper aluminum enclosure, this indicator is built to withstand harsh industrial environments. Its clear LCD meter, scaled from 0-100%, allows for quick and convenient on-site monitoring of pressure, flow, level, or temperature measurements, enhancing operational awareness and safety.
