Dynamic pressure measurement using Fabry-Perot optical interferometer
Eliminates the need for semi-infinite tubes for monitoring gas turbine combustion dynamics – removes risk of fluid build up
Intrinsically safe for use in explosive atmospheres
No requirement for a charge amplifier or galvanic separator
SPECIFICATION
The PD11 optical sensing system measures dynamic pressure in harsh environments and is ideal for gas turbine combustion monitoring. The sensor incorporates a micromachined sapphire sensing element packaged with a high temperature fibre-optic lead-out to form a unique passive sensor configuration.
The properties of the sensor make it suitable for directly mounting on gas turbine combustors. The high reliability passive optical element provides a unique capability for continuous condition monitoring of gas.
