NA6 Digital Meter With Bargraph

NA6 series meters with multicoloured bargraphs have an universal input destined to measure temperature, resistance, voltage from shunts, standard signals, d.c. voltage and d.c. current. They can find application in various industrial fields, e.g. food industry, intermediate pumping stations, sewage treatment plants, chemical industry, weather stations, breweries. They are destined for the visualization of the measured value and evaluation of change trends of checked technological processes. They can also find application in automation systems where programmed controllers are applied.

NA6 meters can have in option: a continuous analogue output, a relay output, open collector (OC) type outputs and an RS-485 digital output. They are programmed by means of the keyboard and through RS-485.
NA6 meters realise following functions:
– measurement of the input quantity and displaying it on the display and the bargraphs,
– recounting of the input signal into indication on the base of the individual linear characteristic,
– arithmetical functions on channels: addition, subtraction, multiplication, division, raising to a power, extraction of roots,
– programming of colours and bargraph resolutions,
– signalling of alarm value setting exceedings,
– recording of the measured signal in programmed time segments,
– storage of maximal and minimal values,
– programming of the measurement averaging time,
– programming of the indication resolution,
– deadlock of the parameter introduction by means of a password,
– conversion of the measured quantity into a voltage or current output signal,
– service of the RS-485 interface in MODBUS protocol, both in ASCII and RTU mode.

Next to programmable measuring functions meters have many additional functions:

  • measurement of the input quantity and displaying it on the LED display and on the bargraph,
  • evaluation of the input signal into the indication on the base of the individual 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,
  • memorisation of maximal and minimal values,
  • 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,
  • fixing in the panel
