Tek-LCD 7800A NEMA 4X Loop-Powered Process and Level Indicator is one of Tek-Trol's most advanced and feature-packed plastic, field-mounted, loop-powered indicators. The fact that this meter is loop-powered means that there is no need to run additional, costly power lines. The Tek-LCD 7800A is built in a NEMA 4X and IP65-rated plastic enclosure which can stand up to even the harshest environmental conditions. It features a dual-line display that can be easily scaled in the field for any 4-20 mA analog input. The display has a five digit upper display, a seven alpha-numeric character lower display, and comes with a backlight standard. Two features that make the Tek-LCD 7800A stand out are its wide viewing angle display and SafeTouch® through-window buttons. These buttons allow the meter to be programmed and operated through the cover window, thus eliminating the need to remove the cover in dirty or wet environments.
