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.
