Introduction
The ProtEX-FarVu PD6870-SS is a rugged, stainless
steel, explosion-proof, loop-powered meter with 1"
display digits ideal for demanding applications in
hazardous areas or in the harshest environmental
conditions. It will operate down to -40°C and can be
installed in areas where the temperature gets as cold
as -55°C, however, the display will cease functioning.
The meter derives all of its power from the 4-20 mA
loop with a small 1 volt drop for easy installation in
almost any system.
The meter is programmed using four easy to access
front-mounted
potentiometers with no complex or difficult
to read
programming menus necessary for setup.
The numeric display will read from -1000 to 1999 over
a 2000 count user adjustable scaling span. The
backlight feature lets you see the display under any
lighting condition and is powered from the 4-20 mA
loop with no additional power supply required. The
backlight can be enabled or disabled via alternative
wiring of terminal block.
The enclosure is provided with two conduit openings.
The cast-in mounting flanges on the enclosure make
it convenient for pipe or wall mounting.
