PD6800 ProtEx-Pro Explosion-Proof Loop-Powered Process & Level Meter
The ProtEX-Pro PD6800 is one of Precision Digital’s most advanced and feature-packed explosion-proof, loop-powered indicators. The fact that this meter is loop-powered means that there is no need to run additional, costly power lines into a hazardous area. Like all ProtEX products, the PD6800 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. The display has a five digit upper display, a seven alpha-numeric character lower display, and is available with a twenty-segment bar graph for level applications. Two features that really make the PD6800 stand out are its wide viewing angle display and SafeTouch® through-glass buttons. These buttons allow the PD6800 to be programmed and operated through the glass, thus eliminating the need to remove the cover in a hazardous area.
