Dynamic Pressure Sensor PT1100

Category: Pressure Sensor

The PD1100 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

Sensing System

  • 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

Fibre optic cables are used to connect the two parts of the sensor system together. It’s important that the connector are cleaned before they are joined. Here’s a short video to explain this simple cleaning procedure.

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).
