ABB AWT420 analytical transmitter
ABB has expanded its digital analytical measurement range of solutions with the launch of the AWT420 transmitter. The 4-wire, dual-channel analytical transmitter measures multiple parameters in a single device, optimising process performance for water usage and treatment.
Capable of measuring multiple parameters including pH/ORP, conductivity, dissolved oxygen and turbidity, the AWT420 is said to be versatile and user-friendly.
The product offers interchangeable communications and sensor modules enabling the transmitter to be upgraded as required without having to purchase additional units. Modules for HART, Profibus, Modbus or Ethernet communications and ABB’s digital EZLink pH/ORP, conductivity, dissolved oxygen or turbidity sensors are available.
Each pluggable module is factory calibrated and can be removed and exchanged via the transmitter’s hinged door, allowing fast upgrading in the field. The transmitter’s intuitive interface, simple set-up menus and one-button calibration routine also eliminate the need for specialist installation or commissioning expertise.
Additional operational flexibility is provided by the transmitter’s dual-channel design. Users can opt for analog or digital sensors or a mixture of the two. The inclusion of integrated PID enables the transmitter to provide direct or reverse acting control. In pH applications, this function can also be used to provide dual acid/base control.
The transmitter’s easy-to-navigate, full-colour TFT display means sensor data can be quickly located and viewed in situ via the device’s display or saved onto an internal SD card for analysis using ABB’s DataManager Pro tool. The inclusion of Bluetooth technology also enables access via a smartphone using ABB’s EZLink connect app.
