Dynamic Pressure Sensor PD11
The PD11 optical sensing system measures dynamic pressure in harsh environments and is ideal for gas turbine combustion monitoring. The sensor incorporates a micro-machined 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 turbine combustion dynamics.
PRODUCT FEATURES AND BENEFITS
- Optical sensing enables:
- Extreme temperature operation up to 1000°C
- Harsh environment operation
- EMI immunity – start-up pyroelectric noise is nil
- Asset protection though autonomous monitoring
- Eliminates the need for semi-infinite tubes for monitoring gas turbine combustion dynamics – removes risk of fluid build up
- Closer proximity to combustion events enables an:
- Increased acoustic bandwidth capability
- Enhanced event characterisation
- Intrinsically safe for use in explosive atmospheres
- No electrical systems required in ATEX zone
- No requirement for a charge amplifier or galvanic separator
- Small form factor digital interrogator (signal conditioner) mounted on DIN rail located with control electronics
- Dynamic pressure measurement using Fabry-Perot optical interferometer
Dynamic Pressure Sensors
Maximum continuous background pressure/ Bar
- Flexible conduit length: Standard length 1m, the options are 2m or 3m.
- Patch cord: Standard option is anything up to 100m in length of LXCR FC/APC Optical Fibre Cable, longer lengths can be provided on request.
- Adaptor: Please contact us to discuss your requirements.
- Other pressure ranges available upon request.
- The selected sensor part number will be built into the PD11 dynamic pressure sensing system, which comprises a sensor, interrogator and plate retainer to secure the sensor.
LASER SAFETY NOTE: The sensor system contains a light source that has been certified as a CLASS 1 LASER, so you should not look into the sensor when it’s switch on (green light showing on the interrogator).
