  • Introduction:
    • AST3003 can be installed into thermocouple or RTD junction box to integrated structure
    • Suitable for resistance temperature detectors (RTD), thermocouples (TC), resistance and voltage signal input to measure the temperature of solid surface, liquid and gas medium within - 200 to 1800°C
    • LCD display with backlight has both Chinese and English language operation menu function which makes field measurements more intuitive and convenient
    • Transmitter features wide measurement range and high accuracy, in the industrial field 4-20mA signal output directly, so widely used in the petrochemical industry, electric power, metallurgy and so on
  • ​Applications:
    • Standard: RTD/TC
    • Ohms and mV signal
    • Two wire 4-20mA current loop and HART
    • 2-, 3-, and 4-wire RTD input
  • Specifications:
    • Power supply:
      • Transmitter operates between 14 and 45V DC, by the distributor or regulated power supply, and the general work power is 24V DC
    • Electronic isolation:
      • Sensor signal input and output isolation (isolation voltage up to 2000V DC)
      • Resistance to industrial frequency interference, to ensure that the transmitter work reliably in bad industrial environment
    • Configuration:
      • Hart device configurator, local button, software support Hart protocol
      • Cold-junction compensation
      • Built-in cold junction compensation, compensation accuracy ±0.5°C of span
  • ​Sensor input type:
    • RTD type: Pt100/Pt500/Pt1000/Cu50/Cu100
    • TC type: B/E/J/K/N/R/S/T
    • Resistance: 0-400Ω/0-2000Ω
    • Voltage: -60 to +60mV/-120 to +120mV
    • Some non-standard thermocouples can be customized
  • ​Load characteristic:
    • Load characteristics: RL≤ (Vs-14V)/0.022
    • RL- maximum load resistance vs- power supply
    • Hart communication requires a loop resistance (including signal receiving resistance and signal transmission wire resistance), between 230 and 600 ohms
    • Operating temperature: -25 to 75°C
    • Electrical damping: 0.1-16s to choose
    • Output: 4-20mA (maximum 22mA and minimum 3.8mA)
    • Communication: Hart
