High-Temperature Sensors for Gas and Steam Turbine Monitoring

Advanced Combustion Dynamics and Condition Monitoring Solutions

For more than 50 years, IMI Sensors has supported the gas and steam turbine industries with high-performance sensing solutions. Whether monitoring combustor dynamics in gas turbines or detecting pressure and vibration fluctuations in steam turbines, IMI helps operators and OEMs reduce downtime, improve safety, and extend equipment life.

Sensors for Combustion and Condition Monitoring

IMI Sensors provides robust pressure and vibration solutions for gas and steam turbines, designed to deliver accurate and reliable performance in high-temperature environments.

Our UHT-12™ pressure sensors and charge mode accelerometers are built for direct turbine mounting and can withstand extreme temperatures up to 1200 °F (649 °C). For moderate heat zones, ICP® accelerometers operate reliably up to 325 °F (162 °C), offering simplified installation with internal electronics. In lower-temperature locations outside the turbine enclosure, ICP® pressure sensors provide a cost-effective remote monitoring option with excellent signal integrity.

Product applications include:

  • Detecting high-frequency pulsations and dynamic pressure spikes
  • Monitoring vibration in combustor zones and other high-heat areas
  • Identifying early signs of combustion instability
  • Supporting performance analysis in lean-burn, dual-fuel, and heavy-duty turbines
  • Enabling emissions control and root cause diagnostics
  • Using remote pressure sensors for easier access and maintenance

Why Leading Power Providers Choose IMI Sensors

Our sensors are engineered to survive extreme temperatures, vibration, and corrosive atmospheres while maintaining exceptional measurement accuracy.

Certified models (ATEX, CSA, IECEx) are available to meet global compliance needs, with options for hazardous environments and intrinsically safe applications. With fast global fulfillment and decades of field-proven reliability, IMI helps facilities stay online, compliant, and protected.

Expert Support for Sensor Selection and Integration

Choosing the right sensor for your turbine application can be complex—but IMI is here to help. Our team of experts will guide you through selection based on fuel type, turbine design, location, and temperature requirements. Whether retrofitting legacy systems or outfitting a new build, we'll help match your needs with the ideal pressure or vibration sensor. Contact us or request a quote today.
