Aztec AWT440

Multi-input transmitter

Measurement made easy

Introduction

The Aztec AWT440 is a universal multi-input 
transmitter that uses ABB’s Aztec 400 range of 
advanced digital sensors for monitoring the key 
parameters in municipal and industrial water / 
wastewater treatment.

The transmitter has multiple sensor capability that 
enables it to control and display information from 
up to 4 sensors.

These Commissioning instructions provide 
installation and basic operating procedures for the 
Aztec AWT440 transmitter.

For information on the sensor, including installation, 
commissioning, operation and maintenance 
procedures, refer to the specific sensor manual.
