WIRELESS SENSORS INCREASE TOXIC GAS SAFETY AT WORKSITES

Emerson Automation Solutions has introduced two new Rosemount 628 gas sensors to measure carbon monoxide and oxygen depletion, alongside the existing sensor to monitor hydrogen sulphide.

The sensors are used in the Rosemount 928 wireless gas monitor, which is a highly versatile platform for monitoring hazardous conditions in process plants, remote wellheads, pipelines, storage terminals and other facilities. It can be easily deployed using a WirelessHART network in areas considered too impractical or expensive for the installation of conventional wired infrastructure. Once monitors are integrated into the wireless network, users can simply check the status of the remote monitoring system gas levels.

To simplify installation and maintenance, the 928 has hot-swappable main components, including the power module and the 628 sensor. Both are intrinsically safe and can be replaced in the field in minutes without the need for tools. The sensor’s calibration information is stored within the sensor, not the transmitter, which allows users to calibrate the sensor in a non-hazardous location and take it to the field for quick exchanges with installed sensors. This further enhances workers’ safety by minimising their time spent in potentially hazardous locations.

The first Rosemount sensor was designed for hydrogen sulphide detection, given the ubiquity of this gas in the process industries, and the monitors have been installed around the world for this purpose. With the addition of the new sensors for carbon monoxide and oxygen depletion, these monitors can now be used for other applications, or additional monitors can be deployed. If and when process conditions change, monitors can be moved as necessary, as long as they are placed within the coverage area of the WirelessHART network.

Carbon monoxide can be released by a variety of combustion processes, and concentrations above 1500 ppm are immediately dangerous to life and health. Processes able to consume oxygen can reduce atmospheric content in given areas, and any situation where oxygen drops below 19.5 per cent is also dangerous. In many cases, more than one condition may exist at a given time, compounding the hazard.

“Hydrogen sulphide monitoring is vital to personnel safety, leading many facilities to install Rosemount 928 wireless gas monitors,” says Joshua Hernandez, Global Product Manager, Flame and Gas Detection at Emerson Automation Solutions. “Having the ability to monitor for oxygen depletion and carbon monoxide is a major step forward in wireless gas monitoring.

“Companies can now solve a long-time challenging safety issue simply and cost-effectively, which shows the power of wireless network technologies. Current wireless network users can benefit from the new gas sensing types which greatly increase toxic gas safety at their sites.”
