NOTICE
AWT210 2-electrode conductivity sensor modules are supplied
standardized to theoretical sensor characteristics. Following
installation, but before use, a process calibration should be
performed to ensure optimum accuracy. For 2-electrode
conductivity sensor calibration procedures see page 44.

Sensor type RTD wiring
TB4 2-lead
NOTICE
AWT210 4-electrode conductivity sensor modules are supplied
standardized to theoretical sensor characteristics. Following
installation, but before use, a process calibration should be
performed to ensure optimum accuracy. For 4-electrode
conductivity sensor calibration procedures see page 45.

Toroidal sensors

Sensor type RTD wiring
TB4 2-lead
NOTICE
AWT210 toroidal conductivity sensor modules are supplied
standardized to theoretical sensor characteristics. Following
installation, but before use, a process calibration should be
performed to ensure optimum accuracy. For toroidal
conductivity sensor calibration procedures see page 45.
