The Tek-LCD 7801B is one of Tek-Trol's most advanced and feature-packed explosion-proof, loop-powered indicators designed specifically for level applications that require a feet & inches display. The Tek-LCD 7801B can indicate up to 699 feet, 11, and 15/16 (or 7/8) inches. The Tek-LCD 7801B explosion-proof level indicator carries FM, CSA, ATEX, and IECEx approvals for use in hazardous areas. 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 7801B stand out are its wide viewing angle display and SafeTouch^® through-glass buttons. These buttons allow the Tek-LCD 7801B tank-side indicator to be programmed and operated through the glass, thus eliminating the need to remove the cover in a hazardous area.
