2.2 CYLINDER PRESSURE SENSORS FOR ENGINE DEVELOPMENT
GU24DK
TIGG1887A.01
The GU24DK is a sensor which combines the convenient installation
of M8 thread-type sensors with high accuracy and robustness that is
required for typical research and development work. It has thermally
optimized piezoelectric elements. The sensor is equipped with built
in SID for SDM.
