en.Wedoany.com Reported - Emerson has added combustible gas detection to the Rosemount™ 928 Wireless Gas Monitor, enabling monitoring of percent lower explosive limit (%LEL) on the secure WirelessHART platform. This update allows combustible hazard monitoring in remote or hard-to-wire locations without the need for additional power or expensive signal wiring.

Dave Ruhland, Global Flame and Gas Product Manager for Emerson's Measurement Instrumentation business, said that adding combustible gas detection to the Rosemount 928 gives customers greater flexibility when safety requirements change. Plants can extend their wireless gas detection strategy to cover combustible hazards on existing WirelessHART platforms, simplifying installation and supporting reliable monitoring in more hard-to-reach areas across the facility.

The updated Rosemount 928 device supports a measurement range of 0% to 100% LEL. This provides users with early warning and full visibility of combustible gas hazards, helping them detect risks earlier and respond more effectively as situations escalate.

The combustible sensing technology is designed to help reduce long-term maintenance. The sensor does not rely on consumable elements such as catalytic beads, which can degrade in performance from repeated exposure to gas, thus supporting longer maintenance intervals and reducing the need for frequent recalibration.

Secure WirelessHART communication transmits combustible gas data in real time, enabling deployment in hard-to-reach areas without additional power or signal wiring. This update aims to complement existing gas detection solutions by helping teams add monitoring points in locations where logistics make hardwiring impractical or cost-prohibitive.
