The Tek-LCD 7801A is one of Tek-Trol's most advanced and feature-packed plastic, field-mounted, loop-powered indicators designed specifically for level applications that require a feet and inches display. The Tek-LCD 7801A can indicate up to 399 feet, 11, and 15/16 (or 7/8) inches. The Tek-LCD 7801A 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. Two features that make the Tek-LCD 7801A stand out are its wide viewing angle display and SafeTouch^® through window buttons. These buttons allow the Tek-LCD 7801A tank-side indicator to be programmed and operated through the cover window, thus eliminating the need to remove the cover in dirty or wet environments.
