ATT1000 : Temperature Transmitter

ATT1000 Series

ATT1000 two-wire input temperature transmitter is a high performance device that receives Thermocouple/RTD/ohm/
mV input and output mA with HART communication protocol.
Three internal keys to set parameter. Zero span calibration can be achieved either by HART or keypad.


 ● Updating time of output current in 90 ms
 ● Backlit LCD display rotatable to any angle
 ● Two years stability of 0.1%
 ● Accuracy +/-0.1% of Span
 ● Parameter setting by keypad directly
 ● 4-20 mA output plus direct digital  HART communication
 ● Automatic zero calibration by press-button
 ● Explosion proof and weather proof housing
