Overview

The AWT210 HART® transmitter provides either a 4 to 20mA
analog signal (conventional analog), a 4 to 20mA analog signal
with superimposed digital signal (HART point to point analog),
or a polled digital signal (HART multi-drop). Using HART
communications, many functions normally requiring the use of
the local user-interface can be accessed remotely using HART
communication devices.
Four variants of AWT210 are available for use with pH, ORP,
pIon, and conductivity sensors.
The device has four dynamic variables. The device does not
have any device variables.
The analogue output of this device corresponds to the primary
variable (pH, ORP, pIon, Ion concentration, conductivity, or
concentration), outputting 4 mA at the lower range value and
20 mA at the upper range value.
Supported Sensors:
• pH
• 2-electrode conductivity
• 4-electrode conductivity
• toroidal conductivity
The ABB AWT210 analyzer complies with HART Protocol
Revision 7.0.
