Introduction 

The PD6700 is a rugged, field-mount, loop-powered 
NEMA 4X meter fully featured for demanding 
applications in harsh environmental conditions. The 
meter derives all its power from the 4-20 mA loop. It is 
programmed using the four SafeTouch 
through-window buttons, without removing the cover, 
and can be scaled with or without a calibration signal. 
The numeric display will read up to 99999 and the 
alphanumeric display can be programmed to show 
any combination of numbers and letters up to seven 
characters long for use as engineering units, the 
process identification tag or a display for the 
calculated volume when using for level applications. 
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 three threaded conduit 
holes and integrated pipe or wall mounting slotted 
flanges.
