Kistler has introduced what it says is world’s first high temperature accelerometer for the monitoring of gas turbines. Designed for long-term use at up to 700° C, the piezoelectric sensor – made in Switzerland – is not pyroelectric and does not show any popcorn effect, offering manufacturers and operators of gas turbines new options for monitoring the combustion stability.The efficient and secure operation of gas turbines relies upon stable combustion processes. These have to comply with increasingly strict regulations, including flexible operation on different fuels and minimal emissions.
