ABB develops future-proof new analytical transmitter

Swiss-Swedish automation expert ABB has developed a new analytical transmitter that leverages plug-and-play technology to deliver a cost-effective and future-proof solution for industrial pH and conductivity measurement. PIF reports on this state-of-the-art new transmitter technology.

Low-power, high-performance transmitter

ABB has taken an innovative approach to transmitter design with its new AWT210 single-channel, two-wire analytical transmitter for the 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 by optimising plant control and availability.

The low-power, high-performance analytical transmitter is built around single sensor, interchangeable and modular plug-and-play technology. This means that a major benefit of the AWT210’s 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.

Optimal safe performance

Operational simplicity is at the heart of the AWT210. Based on ABB’s common intuitive HMI, users can easily navigate the analytical transmitter. Easy setup menus provide step-by-step guidance and routine calibration tasks can be initiated at the touch of a button.

AWT210 pH and conductivity systems ensure optimal safe performance in the harshest of applications. This, combined with greater user flexibility and environmental compliance, make them ideal for the oil and gas, pulp and paper, metals and mining, and chemical and petrochemical industries.

Highly flexible transmitter design

The highly flexible design of this ABB analytical transmitter 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.

Intrinsically safe and non-incendive versions

With its range of wall, pipe and panel mounting options and IP66 rated enclosure, the AWT210 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 only perform tasks within their specific profiles, with a choice of read-only,
calibrate and advanced security access levels.
