Explosion Proof Field Mount Loop Powered Display Model LP420
The LP420 Loop Powered Display provides digital indication of a 4/20 mA or 10/50 mA process loop signal. The display takes its operating power from the loop current and requires no other source of power.
Wide-ranging zero and span adjustments plus switch-selectable decimal point location and trailing zero allow the display to be calibrated in engineering units. An Engineering Units/Loop Current switch permits a quick check of the process signal without recalibration.
The LP420 is mounted in an explosion-proof housing and operates from -40° to 185°F (-40 to 85°C). The circuit boards are conformal coated for protection from humidity and contamination.
Displaying process variables where line power is NOT available, and in hazardous (explosive) atmospheres.
The LP420 is mounted in a Killark HK Series explosion-proof housing.
