I Introduction
The AST3003 can be installed into thermocouple or RTD junction box to integrated structure. It is 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 -200~1800 ºC. The LCD display with backlight has both Chinese and English language operation menu function which makes field measurements more intuitive and convenient. The transmitter features wide measurement range and high accuacy, in the industrial field 4 ~ 20 mA signal output directly, so widely used in the petrochemical indus- try, electric power, metallurgy and so on.
Application
Standard RTD,TC
Ohm and mV signal
Two wire 4~20mA current loop &HART
2-, 3-, and 4-Wire RTD input
II Specifications
Power Supply
The transmitter operates between 14 and 45 VDC, by the distributor or regulated power supply, and the general work power is 24 VDC.
Electronic isolation
Sensor signal input and output isolation (isolation voltage up to 2000 VDC)
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 ±0.5ºC of span
Sensor input Type
RTD type Pt100/Pt500/Pt1000/Cu50/Cu10
TC type B/E/J/K/N/R/S/T
Resistance 0~400Ω / 0~2000Ω
Voltage -60mV~+60mV / -120mV~+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: -25~75ºC
Electrical Damping: 0.1~16s to choose
Output: 4~20mA(max 22mA and min 3.8mA)
Communication: HART
