Rosemount™ 925 Fixed Gas Detection Transmitter

Proven NDIR gas detection with smart sensor intelligence—designed to reduce maintenance, simplify operations, and maximize safety uptime in harsh, hazardous environments.

The Rosemount™ 925 Fixed Gas Detection Transmitter delivers dependable combustible gas detection using proven NDIR technology combined with a smart sensor architecture engineered for long term stability and low maintenance. Purpose built for fixed combustible gas applications, the Rosemount 925 prioritizes measurement reliability and operational simplicity over feature heavy detector platforms. Its NDIR sensing technology resists poisoning and drift while operating independently of oxygen, making it well suited for harsh and inert environments. Smart sensor design stores calibration and configuration data at the sensor level, reducing commissioning effort and simplifying sensor replacement. With global hazardous area approvals and industry standard integration, the Rosemount 925 supports consistent, scalable deployment—helping safety systems stay online with fewer maintenance touchpoints and lower lifecycle costs.
