Multimeter AR518

Digital meter for temperature and analogue standard signals, retransmission analogue output, RS485, display 25mm, panel-type 144x72mm

Product Description

  • digital meter of temperature and other physical quantities (humidity, pressure, level, speed, etc.) converted into a standard electrical signal (0/4÷20mA, 0÷10V, 0÷60mV, 0÷2.5 kΩ)
  • universal thermometric and analogue measuring input with the memory for storing minimum and maximum measured values:
    • thermoresistance Pt100, Ni100, Pt500, Pt1000
    • thermocouple J, K, S, R, T, B, E, N
    • current 0-20 mA, 4-20 mA
    • voltage 0-10 V, 0-60 mV
    • resistance 0-2500 Ω
  • LED display with programmable brightness
  • remote data display via RS485 (MODBUS-RTU, SLAVE)
  • BIN programmable digital input for changing operational mode of the meter:
    • manual / automatic mode for analogue output
    • keyboard lock
    • Display HOLD function
  • analogue output 0/4÷20mA or 0/2÷10V (retransmission, alarm/control, manual)
  • Manual mode for the analogue output (open control loop), for setting the output value within 0 ÷ 100%
  • built-in 24Vdc power supply for supplying on-site transducers
  • RS485 serial interface, galvanically isolated, MODBUS-RTU
  • compensation of line resistance for resistance sensors
  • temperature compensation of thermocouple cold ends
  • programmable input, range of indications (for analogue inputs), options for alarm, display, access and other configuration parameters
  • access to configuration parameters is protected by the user's password
  • methods for configuring parameters:
    • via membrane keyboard (IP54) located on the front panel of the device;
    • via RS485 or PRG port (programmer AR955) and freeware: ARsoft-LOG (Windows 7/8/10)
  • software and programmer allow you to view the measured value and quickly configure single or few sets of parameters previously saved in the computer for re-use, e.g. in other meters of the same type (duplicate configuration)
  • panel housing, IP54 from the front
  • high accuracy, long-term stability and immunity to interference
  • optionally (when ordered): 24V ac/dc power supply adapter, analogue output 0/2÷10V and RS485 interface
