Multimeter AR503

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
• 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:
  • programming via keypad accessible by removing the front shield
  • via RS485 or PRG port (programmer AR955/GP) 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
