With the move toward increased fuel efficiency and lower exhaust emissions, today’s gas turbine engines are based on technological innovation yet also bring potential problems. Burning a leaner flame keeps NOx emissions low but at the same time increases instability (combustion dynamics) in the gas turbine engine. This instability can damage components in the combustion chamber such as nozzles, baskets and transition pieces, as well as downstream components such as blades, resulting in downtime and loss of revenue.

Charge mode pressure sensors can withstand continuous temperatures up to 1200°F, making them ideal for on-turbine pressure monitoring. Their high-impedance charge output can be converted into a low-impedance voltage output with one of IMI complementary charge amplifiers. These charge output pressure sensors feature UHT-12 TM sensing crystals, designed for more accurate, lower noise measurements during large temperature variations.

As with all PCB® instrumentation, these sensors are complemented with toll-free applications assistance, 24-hour technical support, and are backed by a no-risk policy that guarantees total customer satisfaction or your money refunded.

Highlights include:

• Frequency range of up to 20kHz (1.2 million pm)
• Sensitivity: 6.0pC/g (87pC/bar)
