ABB Offers Innovative pH, Redox (ORP) and Conductivity Transmitter

Sept. 24, 2019

ABB has taken an innovative approach to transmitter design with its new AWT210 single-channel two-wire transmitter for measurement and control of pH, redox (ORP) and conductivity in hazardous and non-hazardous industrial applications. The modular design reduces process downtime and overall operations expenditure while improving safety and boosting performance.

The low-power, high-performance transmitter is built around single sensor interchangeable plug-and-play technology, which enables it to handle future sensor technologies such as ABB’s digital EZLink sensors. Based on ABB’s common HMI, users can easily navigate the device. This feature, combined with greater user flexibility and environmental compliance, makes the transmitter ideal for the oil and gas, pulp and paper, metals and mining, and chemical and petrochemical industries.

The same unit can be used with pH, redox (ORP) and ion selective sensors as well as two- and four-electrode and toroidal conductivity sensors. Factory-calibrated modules for the different sensor types can be quickly fitted and exchanged via the transmitter’s hinged door, enabling easy upgrading and maintenance in the field.

This same approach applies when integrating the AWT210 into different control systems, equipped with a range of exchangeable modules available for 4-20mA with HART, FOUNDATION Fieldbus and Profibus PA communications protocols.
