Programmable meters with multicolour bargraph indicators NA3 type are destined to measure and recording d.c. current or d.c. voltage, temperature, resistance and other non-electrical magnitudes like: level, flow, pressure, humidity. NA3 type is Horizontal with 1-measuring channel in 3 options: with bargraph, with bargraph and display, only with display. Meters with bargraph are devices ensuring both a high measurement accuracy and very well visualization of the measuring process courses. Very well visualization 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 destined 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. Features : • Universal input for the measurement of d.c. current, d.c. 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 (750samples), • Current or voltage analog output, • Communication in SCADA systems (RS485/Modbus interface RTU and ASCII) Borna Niroo Karan (Bornika) is the exclusive agent of LUMEL in the fields of consultation , sales and distribution of power industry products including Horizontal Bargraph products .
