Emerson gas sensors increase toxic gas safety09 July 2019
Emerson has introduced two new Rosemount 628 Universal Gas Sensors to measure carbon monoxide and oxygen depletion, in addition to the existing capability to monitor hydrogen sulphide.
These additions to the series are said to enable a broader range of hazardous situations to be monitored using the Rosemount 928 Wireless Gas Monitor platform.
The Rosemount 928 Wireless Gas Monitor is a platform for monitoring hazardous conditions in process plants, remote wellheads, pipelines, storage terminals and other facilities. It can be 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, personnel can simply check the status of the remote monitoring system gas levels.
To simplify installation and maintenance, the Rosemount 928 Gas Monitor has hot-swappable main components, including the power module and the Rosemount 628 toxic gas sensor. Both can be replaced in the field in minutes without the need for tools.
The Rosemount 628 sensor’s calibration information is stored within the sensor, not the transmitter. This allows users to calibrate the sensor in a non-hazardous location and take it to the field for quick exchanges with installed sensors.
The first Rosemount 628 Universal Gas Sensor was designed for hydrogen sulphide detection. With the addition of sensors for carbon monoxide and oxygen depletion detection, these monitors can now be used for other applications, or additional gas monitors can be deployed. When and if process conditions change, monitors can be moved as necessary, so long as they are placed within the coverage area of the WirelessHART network.
“Hydrogen sulphide monitoring is vital to personnel safety, leading many facilities to install Rosemount 928 Wireless Gas Monitors. Having the ability to monitor for oxygen depletion and carbon monoxide is a major step forward in wireless gas monitoring,” says Joshua Hernandez, global product manager for flame and gas detection at Emerson Automation Solutions. “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.”
