Gas Sensors

RM’s GSENS series consists of online, real-time gas-in-oil sensors designed for continuous Dissolved Gas Analysis (DGA) in power transformers. These sensors act as early-warning tools by detecting gases generated during thermal and electrical faults in transformer insulation systems.

By continuously monitoring critical gases such as Hydrogen (H₂) or multiple fault gases (depending on the model), RM’s gas sensors help utilities and industrial customers identify incipient problems long before they evolve into serious failures. This enables predictive maintenance, improved reliability, and reduced unplanned outages.

Built for harsh substation environments, the GSENS sensors are rugged, stable, maintenance-free, and easy to integrate with SCADA, RM EYE, or other monitoring platforms. They support modern digital communication protocols, offer fast response time, and require no consumables, making them ideal for long-term transformer health monitoring.

Typical characteristics of RM Gas Sensors:

• Continuous online measurement of dissolved gases in transformer oil

• Early detection of thermal and electrical faults

• Long-term stability and drift-free operation

• Digital communication for integration with monitoring software

• Compact design suitable for retrofit or new installations

• No consumables, minimal maintenance

In summary, RM’s gas sensors form an essential part of a modern transformer condition monitoring ecosystem, enabling operators to shift from reactive to predictive asset management through accurate, real-time gas profiling.
