Wireless gas sensors increase toxic gas safety

08 July 2019

Emerson has introduced two new Rosemount628 Universal Gas Sensors to measure carbon monoxide and oxygen depletion in addition to the existing capability to monitor hydrogen sulphide. These additions 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 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 gas monitor has hot-swappable main components, including the power module and the Rosemount 628 toxic gas sensor. Both are intrinsically safe and can be quickly replaced in the field. The 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. This further enhances personnel safety by minimising their time spent in potentially hazardous locations.
