Cylinder pressure sensors for engine development
These piezoelectric sensors measure the pressure inside the combustion chamber and can be used for research and development measurement tasks. They can be installed into the spark plug bore or glow plug bore with the aid of an adaptor, or into a separate mounting bore in the cylinder head. Beside the wide variety of different sensors in our portfolio, we also offer custom tailored solutions on demand.
