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