High-Temperature Sensors for Combustion Monitoring in Gas Turbines

Supporting combustion diagnostics in modern turbines

For more than 50 years, IMI Sensors has supported the gas turbine industry with advanced measurement solutions for combustion monitoring. Our high-temperature dynamic pressure sensors and accelerometers are engineered to detect unstable acoustic oscillations and pressure pulsations that indicate combustion instability. IMI technology supports both OEMs and plant operators with precise, real-time turbine health diagnostics that improve safety and reduce unplanned shutdowns.

Purpose-built sensors for reliable combustion diagnostics

Combustion instability can lead to performance loss, emissions spikes, and equipment damage. IMI Sensors offers the precise, high-frequency response and thermal endurance needed to monitor combustor dynamics and protect turbine hardware.

  • Dynamic pressure sensors for high-frequency pulsation detection
  • Vibration sensors with high-temperature survivability for combustor zones
  • Accurate combustion instability monitoring for early fault detection
  • Rugged designs proven in heavy-duty, lean-burn, and dual-fuel engines
  • Support for turbine optimization, emissions control, and root cause analysis
  • In-stock inventory for rapid deployment
