PLANT MAINTENANCE, TEST + MEASUREMENT

Plug-and-play technology in new analytical transmitter

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, improves safety and boosts performance by optimising plant control and availability. The low power high-performance transmitter is built around single sensor interchangeable 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. Operational simplicity is key in the AWT210. With ABB’s common intuitive HMI, users can easily navigate the device. Easy setup menus provide step-by-step guidance and routine calibration tasks can be initiated at the touch of a button. The AWT210 pH and conductivity

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.

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 flexible transmitter design enables the same unit to be used with pH, redox 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 fitted quickly and exchanged when required via the transmitter’s hinged door, enabling fast and easy upgrading and maintenance in the field. The same approach applies when integrating the AWT210 into different control systems: it is equipped with a range of exchangeable modules available for 4-20 mA with HART®, FOUNDATION Fieldbus ® and Profibus PA ® communications protocols. 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

SiSi safety gear for women working at heights

This limits the risk of secondary injuries for women, should they be involved in a fall-arrest incident, and it makes the harness more comfortable for women to wear confidently on the work site. “As more women are now working in industrial environments and as traditional gender-based barriers are steadily coming down in sectors once dominated by men, there is a need to provide gender-specific safety wear,” says Ronald. The Sisi range of fall arrest systems is manufactured in South Africa and available to order through leading PPE distributors. Sisi Safety Wear forms part of the BBF Safety Group (BBF) stable.The brand was initially developed to provide safety footwear to suit the contours of a woman’s foot. A decade later Sisi expanded

Sisi Safety Wear has taken another step in its drive to support women in industry – with the launch of a new range of fall arrest systems specifically designed for women who work at heights. Fall arrest systems are harnesses with permanently attached lanyards. Vanessa Ronald, Senior Brand Manager at the company says, “This is a very exciting move for Sisi and again underscores our commitment to women who work in traditionally male-dominated industry sectors. We believe that women should have access to personal protective equipment that has been designed to fit the female anatomy and not that of their male counterparts.” The leading local manufacturer of personal protective equipment (PPE) for women has introduced five different harnesses in its Core and Core+ Ranges, adding to the already trusted line of Sisi protective clothing and footwear. The Core range offers three standard harnesses with permanently attached, single- or double-leg shock absorbing lanyards, with snap or scaffolding hooks. The Core+ Range includes two belted harnesses with permanently attached, double- leg, shock absorbing lanyards, with snap or scaffolding hooks and adjustable shoulder straps. Sisi Fall Arrest Specialist, Ruaan Breedt, explains that the Sisi fall arrest range is especially considerate of the female form and includes a newly developed adjustable and elasticated chest strap.
