Rosemount 928 wireless gas monitor

The Rosemount 928 wireless gas monitor is a fully integrated WirelessHART toxic gas monitoring solution. It is designed to significantly improve safety in areas and applications that were previously considered to be too expensive and difficult to monitor due to remote or difficult-to-access locations, challenging topology and other issues.

Workers approaching sites like wellheads and remote tank batteries for maintenance are constantly in danger of exposure to unplanned releases of toxic gas such as hydrogen sulfide. Monitoring these sites with conventional wired gas detection systems is often cost-prohibitive or logistically impossible. The installation, wiring and commissioning costs for each additional wired device can add tens of thousands of dollars to the instrument’s total installed cost.

The Rosemount 928 gas monitor integrates into a WirelessHART network, eliminating wiring and dramatically reducing installation, commissioning and maintenance costs. Once integrated into the wireless network, personnel simply check the status of the remote monitoring system to know if a maintenance trip is safe.

In addition, the Rosemount 928 gas monitor includes a power module and the Rosemount 628 toxic gas sensor module that are both intrinsically safe and can be replaced in the field in minutes without the need for tools. The Rosemount 628 is a ‘smart’ sensor module, meaning that calibration information is stored within the sensor not the transmitter. This allows users to calibrate the sensor in a non-hazardous location and carry it into the field for quick exchanges with installed sensors.
