PD6801 ProtEX-F&I Explosion-Proof Loop-Powered Feet & Inches Level Meter

New product
 
More info

The ProtEX-F&I PD6801 is one of Precision Digital's most advanced and feature-packed explosion-proof, loop-powered indicators designed specifically for level applications that require a feet & inches display. The PD6801 can indicate up to 399 feet, 11 and 15/16 (or 7/8) inches. Like all ProtEX products, the PD6801 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 really make the PD6801 stand out are its wide viewing angle display and SafeTouch® through-glass buttons. These buttons allow the PD6801 tank-side indicator to be programmed and operated through the glass, thus eliminating the need to remove the cover in a hazardous area.
