Editor’s choice Introducing the AWT210 analytical transmitter
The AWT210 offers plug-and-play technology for industrial pH and conductivity measurement. It is a low-power high-performance solution for hazardous applications. In this Q&A, Julian Edwards, Continuous Water Analysis product manager at ABB, discusses the versatility of this transmitter and how it can improve water treatment efficiency.
Describe the AWT210
The AWT210 is a low-power, high-performance single-channel two-wire transmitter for measurement and control of pH, redox (ORP) and conductivity in hazardous applications.
What key benefits does it offer customers?
The AWT210 offers several great benefits. First is its ease of use. The transmitter uses
pluggable modules that come factory-calibrated, enabling you to get up and running quickly and easily. These can be removed and exchanged via the transmitter’s hinged door, allowing fast upgrading in the field. The transmitter’s high-quality intuitive interface
uses easy navigation and Windows-style scrolling menus, enabling quick and easy access to measurement, diagnostic and audit data. Sensor data can be quickly located and viewed in-situ via the device’s display or communicated via HART, PROFIBUS and FOUNDATION Fieldbus communications to a central control system. The one-button calibration routine also
eliminates the need for specialist commissioning expertise, reducing the costs of installation and commissioning as well as maintenance. A second major benefit is the inclusion of a
range of measures to protect data security. To avoid data tampering, multi-level security access prevents unauthorized configuration or calibration changes. Password protection ensures that changes can only be made by authorized users, with the details of any alterations, including dates, times and the person responsible, stored in an audit trail. Multi-level security access also ensures users can only perform tasks within their specific profiles, with a choice of read-only, calibrate and advanced security access levels. Lastly is the AWT210’s flexibility. Like the four-
wire transmitter module AWT420, the AWT210 can be upgraded as required using the interchangeable modules without having to purchase additional transmitter units. The simplicity of the modular design reduces process downtime
and overall operations expenditure while improving safety and optimizing process and plant up-time. The 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.
Where can the AWT420 be used?
The AWT210 can be used wherever water quality needs to be measured and is particularly useful for industrial applications including chemical and petrochemical, power generation, pulp and paper. power and marine sectors through to water and wastewater treatment plants. With a choice of wall-, pipe- and
panel-mounting options, the AWT210 can be fitted virtually anywhere. There is also a choice of corrosion-resistant polycarbonate or durable metal versions, with cFMus and ATEX / IECEx approvals, making it suitable for both standard and hazardous applications.
