Industrial Application Scenarios

• Turbine Enclosure Monitoring: Detects fuel gas leaks around high-temperature combustion turbine hoods where structural skin temperatures exceed standard sensor ratings.

• Chemical Drying Oven Safety: Tracks solvent vapor accumulation levels directly inside thermal processing ducts to prevent explosive gas concentrations from forming.

• Offshore Oil Rig Wellhead Areas: Mounts to process manifolds in marine environments, providing high corrosion resistance and fast flame path isolation under ATEX mandates.

• Boiler Plant Valve Arrays: Monitors high-pressure natural gas manifold feed systems to execute immediate emergency shutdown protocols upon detection of a 5% LEL breach.
