Reuter-Stokes, LLC

Reuter-Stokes develops and manufactures high-reliability UV flame sensors engineered specifically for GE gas turbines—models LM2500, LM5000, LM6000, and LMS100. Their silica-carbide (SiC) photodiode-based Flame Tracker™ sensors deliver rapid (<0.025 s) and accurate UV flame detection, even in low-NOx, steam-injected, or gas-fog environments. With over 500 million operating hours and more than 25 years of proven service in harsh conditions, these sensors are trusted worldwide.

Certifications & Hazardous-Area Ratings:

• ETL-certified for low-voltage UV sensing

• ATEX and IECEx approved for Zone 1/2 hazardous environments

• SIL-certified to IEC 61508 SIL 3 for use in safety-instrumented systems

What Sets Reuter-Stokes Apart:

• SiC photodiode sensitivity at longer UV wavelengths ensures consistent flame detection in steam and fuel-rich conditions

• No water cooling required (Dry 325 models), minimizing maintenance and simplifying installation

• Fast-connector design and rugged mineral-insulated cabling enable easy field replacement

• Wide operating range (–40 °C to 325 °C at the hot end) and stainless-steel construction deliver long-term durability in extreme turbine environments

Reuter-Stokes UV flame sensors are known for their fast response, rugged performance, and compliance with strict global safety and hazardous-area standards—making them a trusted choice for critical gas turbine combustion monitoring.
