HIGH TEMPERATURE PRESSURE SENSORS FOR COMBUSTION INSTABILITY MEASUREMENT In response to market and regulatory requirements, modern power turbine manufacturers have achieved remarkable decreases in emissions. In particular, NOx emissions have been dramatically reduced through new “lean burn” or “dry low NOx” designs. As is typically the case, these advances have come at a price. The low fuel-to-air ratios of these combustors can result in coupled acoustic and heat release pressure oscillations. Even though the magnitude of these oscillations may be low, even small fluctuations (less than 1 psi)...

NATURAL GAS SUPPLY & PETROCHEMICAL INDUSTRY, HAZARDOUS AREA APPROVED SENSORS Sensors that offer hazardous area approvals are widely used on gas and oil well heads, supply lines, natural gas power engines, multi-stage gas compressors, and other machinery operating in hazardous environments. Piezoelectric pressure sensors offer the capability to detect and monitor dynamic pressure spikes, pulsations, and surges in gaseous or liquid media. Engine pressure sensors offer walk-around or permanent monitoring capability, allowing engine balancing and emissions control. Vibration monitoring has proven...

ACCELEROMETERS FOR WIND TURBINE MONITORING Monitoring vibration levels on wind turbines can help diagnose potential problems at an early stage and help prolong the life of the system. Accelerometers are mounted in various locations within the turbine including the main bearing, the gearbox, and the generator. They can also be used for monitoring the motor in the yaw assembly.
