Loop-Powered Process Meter

Model: DPM-400

The DPM-400 loop-powered digital panel meter allows you to install a local display right where you need it. No power, no problem. This digital panel meter is powered by an existing 4-20 mA loop, making it an ideal display solution for any of your 4-20 mA sensors. It features a dual-line display with a 5-digit alphanumeric top line and an 8-digit alphanumeric bottom line. A common level sensor setup shows input by scale on the top line (such as feet and inches) and a description on the bottom line (such as silo number). Both lines use 14-segment, alphanumeric characters for clear indication of tags, units, or alarm messages. Choose from a general purpose decimal-display, a decimal display with a bar graph, or a feet and inches with a bar graph display.
