IMI Sensors - Combustion Dynamics Instrumentation

Product catalog summary

Overview
IMI Sensors, a division of PCB Piezotronics, specializes in designing and manufacturing sensors and measurement systems for gas turbine markets, focusing on combustion dynamics instrumentation. These systems are crucial for monitoring dynamic combustion measurement and turbine engine performance, especially in the context of increasing fuel efficiency and reducing emissions.

Sensor Types and Applications

Remote Sensors: These are mounted outside the turbine enclosure and connected via sensing lines to the combustors. They are cost-effective and can be serviced while the turbine is operational.
Close Coupled Sensors: Permanently mounted to the turbine, these sensors operate over a wider frequency range and are suitable for high-temperature environments, allowing precise measurement of dynamic pressure phenomena.
On-Turbine Instability Sensors (OTIS): Directly mounted to the combustor basket, these sensors provide continuous monitoring and diagnostics, enabling real-time tuning and emissions control.

Key Sensor Models

ICP® Pressure Sensor Model 121A44: Sensitivity of 1 to 100 mV/psi, measurement range of 50 to 500 psi, with a stainless steel diaphragm.
ICP® Pressure Sensor Model 102M205: Sensitivity of 10 to 100 mV/psi, measurement range of 50 to 5000 psi, with a stainless steel diaphragm.
High Sensitivity Pressure Sensor Series 171: Measurement range of 10 psi, sensitivity of 1100 pC/psi, suitable for close coupling applications.
High Temperature Pressure Sensor Series 176M0X: Sensitivities to 17 pC/psi, measurements up to 20 psi, designed for high-temperature environments.

Vibration Monitoring
Vibration monitoring is essential for diagnosing potential issues in gas turbines, reducing unplanned maintenance and failures. High-temperature accelerometers, such as the Series EX600B1X and Series 357D9X, are designed for extreme heat environments, providing reliable data for turbine monitoring.

Accessories
Various cabling options are available to support sensor installations, including low noise, PFA jacketed cables, and polyurethane cables with different connector configurations.
