Application notes

High Temperature Gas Turbine combustion instrumentation

Our work on direct mount high temperature gas turbine combustion instrumentation versus a ‘stand-off’ or ‘waveguide’ installation. Enhanced sensitivity and pressure signal bandwidth due to direct mount approach.

Hydrogen fuel blend application

Running gas turbines on a hydrogen blend or 100% hydrogen fuel presents several challenges.  Oxsensis have developed a Multi-Measurand system which can monitor static pressure, dynamic pressure and temperature from a single sensor with high accuracy.

Long Term Operation on Utility Scale Gas Turbine

In co-operation with a power station operator, Oxsensis installed a dynamic pressure sensor for long term testing on a 330MW gas turbine.

Oxsensis dynamic pressure measurement on a GE 9E engine

Oxsensis PD11 dynamic pressure sensor was installed on a GE 9E 124MW(e) gas turbine at the Stadtwerke München (SWM) power plant in the south of Munich, Germany. The installation was completed in collaboration with IfTA Systems GmbH.

Optical Technology for Measurement of Exhaust Gas Pressure

In collaboration with the Department of Engineering Science, University of Oxford, we tested a PT1100 sensor in the exhaust of an internal combustion engine.

Optical sensors Vs. Piezoelectric sensors

The German Aerospace Center (DLR) tested Oxsensis optical sensors against piezoelectric sensors.  This technical report details the tests and results showing how optical sensors perform against piezoelectric sensors.

Power to Gas: Hydrogen for Power Generation

GE have published a technical paper detailing how gas turbines can support a low or reduced carbon electrical grid by operating on a wide variety of lower carbon fuels, including current hydrogen capabilities of GE gas turbines, requirements for upgrading existing turbines for operation on hydrogen fuels, and potential future technology options.
