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-measuring channel in 3 options: with bargraph, with bargraph and display, only with display,
NA5 type – vertical, 1-measuring channel, with bargraph and display,
NA6 type – vertical, 2-measuring channels, with 2 bargraphs and 2 displays.
Functions
measurement of the input quantity and displayed on the LED display and on the bargraph,
linear characteristic, arithmetical: raising to a power, extraction of roots(additionally in NA6 type, operations in channels: summation, subtraction, multiplication, division), programming of the bargraph colour and resolution, signalling of the set alarm value exceeding, recording of the measured signal in programmed time intervals, maximal and minimal memory,programming of the measurement averaging time,programming of the indication resolution, lockout of parameter introduction by means of a password, servicing of the RS-485 interface in MODBUS protocol, both in ASCII and RTU mode, galvanic isolation.
