INTRODUCTION
The ProtEX-RT PD6820 is a rugged, explosion-proof loop-powered rate/totalizer fully
featured for demanding applications in hazardous areas or in the harshest
environmental conditions. The meter derives all of its power from the 4-20 mA loop. It
is programmed using the four SafeTouch
® through-glass buttons, without removing
the cover, and can be scaled with or without a calibration signal. The numeric rate
display will read up to 99999 and the alphanumeric total/tag display will read up to
9999999. The alphanumeric display can also be programmed to show any
combination of numbers and letters up to seven characters long for use as
engineering units and/or the process identification tag. The backlight lets you see the
display under any lighting condition and can be powered from either the 4-20 mA
loop or from a separate DC power supply.
The enclosure is provided with two threaded conduit holes and integrated pipe or wall
mounting slotted flanges.
