Cylinder pressure sensors, M5x0.5, new generation / 6054C

Cylinder pressure sensors of Type 6054C are front-sealing sensors in a M5×0.5 bore. They are therefore suitable for various installation techniques, both with or without a mounting sleeve. However, the excellent strain rejection, due to the decoupled measuring element from the sensor housing, allows for installations with no mounting sleeve (i.e., direct installations) in order to achieve excellent results irrespective of strain effects. The pressure sensors are therefore ideally suited for modern engine applications such as the development of powerful compact engines that employ complex cylinder head geometry. This sensor is also ideal for motorcycle and small engine development tasks, as well as in-vehicle measurement applications later in the development cycle. The new PiezoStar crystal from Kistler offers a high sensitivity combined with thermal and mechanical stability. Due to the very compact design and the high natural frequency of the sensor, the influences of engine vibrations, such as valveclosing, are minimized. This pressure sensor has the perfect combination of performance and durability, such that it can be deployed across the full engine development process. It has the required sensitivity and accuracy for early thermodynamic and efficiency studies, combined with the robustness needed for later calibration and validation activities.
