Description

Lumel NA3 Programmable digital meter with multi-colour bargraph indicators are designed to measure and record DC current or DC voltage, temperature, resistance and other non-electrical magnitudes like: level, flow, pressure, humidity.

Features of the NA3 Programmable digital meter:

  • Universal input for the measurement of d.c. current or voltage and temperature.
  • 3 or 7 colour bargraph
  • Programming of bargraph colour depending on the measured quantity value
  • Signalling of set alarm value overflow
  • Storage of measured signal in programmed time segments (750 samples)
  • Current or Voltage analogue output
  • Communication in SCADA systems (RS485/MODbus interface RTU and ASCII)

Meters with bargraph are devices ensuring both a high measurement accuracy and very well visualisation of the measuring process courses.
Very well visualisation of the process is possible through using in meters 3 and 7-coloured bargraph built with diodes made in the gallium nitride technology. They can find application in various industrial fields, e.g. food industry, pumping stations and savage-treatment plants, chemical industry, weather stations, brewing industry and many other fields where they are designed for visualisation of the measured value and evaluation of the monitored manufacturing process change trend. They can also find application in automation systems where programmable controllers are applied.
