Programmable multicolour bargraph indicators NA3, NA5 and NA6 type are designed to measure and recording d.c. current or d.c. voltage, temperature, resistance and other non-electrical magnitudes like: level, flow, pressure, humidity. Bargraph indicators offer both a high measurement accuracy and visualization of the process . Visualization of the process is possible using our 3 and 7-coloured bargraph which are built with diodes made with gallium nitride technology. Applications fields include, e.g.food industry, pumping stations and sewage-treatment plants, chemical industry, weather stations, brewing industry and many other fields where they are destined for visualisation of the measured value and monitoring process variable trends. They can also find application in automation systems where programmable controllers are applied.
NA3 type – horizontal, 1 channel with 3 options - Bargraph only - Bargraph + Display - Display only
NA5 type – vertical, 1 channel - Bargraph + Display
NA6 type – vertical, 2 channel with 2 Bargraphs and 2 Displays
