2.2 CYLINDER PRESSURE SENSORS FOR ENGINE DEVELOPMENT
QC43D
TIGG0538A.01
The QC43D has a mounting thread of M14 and is especially suited for
large diesel engines. It is designed for cylinder bores above 100 mm
and if quartz sensors are preferred. An active water cooling system is
required to protect the quartz in order to ensure long lifetimes and
excellent data reproducibility.
