Sensors - ABB Inc. - Instrumentation DO System

Comprised of the ADS430 optical dissolved oxygen sensor and the AWT440 multichannel transmitter, the DO System from ABB Inc. - Instrumentation provides stability and accuracy for dissolved oxygen measurement in demanding process environments. The ADS430 has EZLink technology and users benefit from plug-and-play connectivity, automatic sensor recognition/set-up, predictive diagnostics and enhanced measurement accuracy. The design allows it to withstand the problems that can affect conventional membrane-based sensors, such as abrasion, fouling or poisoning. The AWT440 universal transmitter enables connections of up to four Aztec 400 digital sensors, enabling monitoring at multiple points without the cost associated with purchasing and installing separate transmitters. 800/435-7365;
