Lumel NA5 PLUS Meter

NA5 PLUS Programmable meters with multicolour bargraphs

NA5 PLUS – Vertical 1-measuring channel with bargraph and display.

Meters with bargraph are devices ensuring both a high measurement accuracy and great visualisation of the measuring process. Great visualisation of the process is possible through using in meters 3 or 7 coloured bargraph built with diodes made in the gallium nitride technology. Application in various industrial fields e.g. food industry, pumping station and savage-treatment plants, chemical industry, weather station, brewing industry and many other fields where they are destined for visualisation of the measured value and evaluation of the monitored manufacturing process change trend.

  • 3 or 7 coloured bargraph with programmable colour switching over
  • Logging of the measured signal in programmed time intervals (800 samples)
  • Universal measuring input
  • Programmable indication characteristic (21-point rescaling) and bargraph magnifier
  • Up to 8 programmable alarm outputs
  • Alarm triggered by the rate of change of the measured signal over time
  • Arithmetical function x², √x.
  • Communication in SCADA systems (RS485/Modbus interfaces)
  • Conversation of any measured value into a current or voltage analogue signal
