Sensor Measures Combustion Instability to Prevent Turbine Damage and Downtime

IMI's Series176 high-temperature pressure sensors detect and measure dynamic pressurephenomena and combustion instability in the extreme heat environments (+986F,+530C) generated by today's gas turbines. These sensors are also ATEX and CSAcertified for use in hazardous areas. The Series 176 high-temperature pressuresensors are ideally suited for gas turbine monitoring with sensitivities to 17pC/psi (2.5 pC/kPa) and ranges from 20 psi (140 kPa) dynamic to 400 psi (2760kPa) static.

By mounting the Series 176 high-temperature pressure sensors tothe combustor, gas turbine operators can rely on critical diagnostics, partfatigue analysis and the ability to continuously monitor and control emissions.Operators also save time during combustion inspections and overhauls due to theelimination of tubing and a purging system. The high frequency capability ofthe Series 176 sensors enables the use of auto-tuning and on-line diagnosticmonitoring systems. These sensors also provide an output that can easilyconnect to legacy combustion dynamics monitoring systems.
