Murata Power Solutions Digital Ammeter, 21.29mm x 33.93mm, ±1 %

The Murata Power Solutions DC Ammeter is the world's first loop-powered digital panel meter with a large, easy-to-read and bright red LED display. All the operating power is derived directly from the loop current itself, no external power supply is required. The large, 0.37in/9.4mm digits exhibit uniform intensity over the entire 4mA to 20mA operating range. Additionally, the total maximum loop voltage drop is only 5V. Its switch and adjustment potentiometers accommodate hundreds of different input current/output-reading combinations. This versatility practically eliminates the need to order more costly, long-lead-time, factory-customized "specials" in applications in which several different-range meters are required. An optional bezel assembly, featuring screw fasteners and a rubber seal, simplifies panel-mounting and provides excellent resistance to environmental dust and moisture.
