The YPP6870 is a rugged, loop-powered meter with 1" display digits in an explosion-proof enclosure for demanding applications in hazardous areas or in the harshest environmental conditions. The meter derives all of its power from the 4-20 mA loop with a small 1 volt drop for easy installation in almost any system. It is programmed using four easy to access front-mounted control dials with no complex or difficult to read programming menus necessary for setup. The numeric display will read from -1999 to 1999 over a 2000 count user adjustable scaling span. The backlight option lets you see the display under any lighting condition and is powered from the 4-20 mA loop with no additional power supply required. The enclosure is provided with two threaded conduit holes and integrated pipe or wall mounting slotted flanges.
