NEMA 4X LOOP-POWERED FLOW RATE/TOTALIZER INDICATOR
The Tek-LCD 7802A is a plastic field mounted loop-powered rate/totalizer fully featured for demanding applications in the harshest environmental conditions. The meter derives all of its power from the 4-20 mA loop. It is programmed using the four through-window 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 has three threaded conduit holes, integrated pipe or wall mounting flanges, and allows for easy installation of tamper seals.
