This instability can damage components in the combustion chamber such as nozzles, baskets and transition pieces, as well as downstream components such as blades, resulting in downtime and loss of revenue. PCB offers a wide range of pressure and vibration sensors to monitor the combustion dynamics of a gas turbine in order to identify and correct acoustic oscillations before they cause …
A combustion chamber pressure sensor is provided for recording a pressure in a combustion chamber of an internal combustion engine, the combustion chamber pressure sensor has a housing having an inner space that is at least partially enclosed by the housing. At least one mechanical-electrical transducer element, for recording the pressure, is accommodated in the housing.
· Marshall Space Flight Center A compact sensor for measuring temperature and pressure in a combustion chamber has been proposed. Heretofore, independent measurements of high pressures and temperatures in combustion chambers have not been performed. In the original intended application, the combustion chamber would be that of a rocket engine.

· These sensors involve drilling into the combustion chamber chamber somewhere. I encountered this issue some years ago and the problem was not pressure sensors, but temparture sensors. Most temperature sensors do not react fast enough. You either bought temp sensors or estimated it from the gas laws.
Combustion chamber pressure loss is necessary from design point of view (Pattern factor and effective cooling, etc.) and flame stabilization considerations. However, total pressure loss also have effect on engine thrust and thrust specific fuel consumption. 2.
FAST TAPS aims at designing, validating and put in operation 8 cooled fast-response wall pressure taps for combustion chamber measurements. The project is based upon a three steps approach, the three technical work packages of the project, with two distinct iterative design and validation loops. In the first step, the measurement devices will be designed according to the desired measurement ...
A solution for measuring the pressure inside the combustion chamber, variable during the motor cycle, consists in integration in the cylinder-head gasket, on the bore’s superior edge, of a pressure sensor. Another solution, applicable on diesel motors, has been developed by Siemens VDO and Federal Mogul and consists in integrating the pressure sensor into the glow spark plug body ( ...
Sensors C1-C4 and C3-C6 are located on opposite sides just after the last high pressure compressor stage and then just before the combustion chamber. For these two pairs of sensors, Fig. 4 shows that the phase difference between the pressure signals is close to pi for domain 1 (compatible with uneven azimuthal modes) and zero for domain 2

· Combustion diagnostics is often performed using digital processing of pressure signals measured using piezoelectric sensor installed in the combustion chamber of the engine. Four-step pressure signal processing consisting of (i) absolute pressure correction, (ii) phasing crank angle, (iii) cycle averaging and (iv) smoothening is used to get cylinder pressure data from the engine ...
Kistler's piezoelectric pressure sensors are used in continuous operation for closed loop combustion control in internal combus-tion engines. They enable the performance of engines to be controlled constantly. This allows combustion optimization for a better efficiency and minimizes emissions. In addition to this, predictive maintenance becomes easier.

able pressure sensors have been capable of surviving the thermal environment of a combustion chamber without the use of sensing lines or helium-filled cavities. Pressure-measurement signals obtained by use of sensing lines or helium-filled cavities have altered power spectra that make the signals unsuitable as feedback signals for control purposes. The proposed sensor would include two ...
