Swiss-based technology company 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 improves safety and boosts performance by optimising plant availability and control while reducing overall operations expenditure and process downtime.
The low-power, high-performance transmitter is built around single-sensor interchangeable modular plug-and-play technology. As a result, a major benefit of its modular design is its ability to handle future sensor technologies such as ABB’s digital EZLink sensors. By simply upgrading the transmitter with the necessary module, operators can avoid the cost and time of purchasing and installing new transmitter units.
The AWT210 is designed for operational simplicity. Users can easily navigate the device with ABB’s common intuitive interface. Easy setup menus provide step-by-step guidance, and routine calibration tasks can be initiated at a touch of a button.
Its pH and conductivity systems ensure optimal safe performance in the harshest of applications. Combined with greater user flexibility and environmental compliance, this makes them ideal for the oil and gas, pulp and paper, metals and mining, and chemical and petrochemical industries.
The highly flexible transmitter design enables the same unit to 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 when required via the transmitter’s hinged door, enabling fast and 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.
With its range of wall, pipe and panel mounting options and IP66 rated enclosure, it can be installed almost anywhere in an industrial process with both intrinsically safe and non-incendive versions for hazardous area installation certified by USFMc and ATEX/IECEx.
To prevent unauthorised modifications to calibration and configuration settings, multi-level security access ensures that users can perform tasks only within their specific profiles, with a choice of read-only, calibrate and advanced security access levels.
