2.2 CYLINDER PRESSURE SENSORS FOR ENGINE DEVELOPMENT
GP15DK
TIGG1892A.01
The GP15DK has the slimmest contour due to a M3 cable connector
and is a robust M5 sensor especially suited for supercharged engines
with high knock events. The Double-Shell™ design decouples the
piezoelectric elements from negative influences of mechanical stresses
which can occur due to the mounting of the sensor into the engine. In
addition to this, it has an improved membrane material and geometry.
This makes the sensor to the standard solution for development
work with heavy knock events and pre-ignition. The sensor could be
equipped with SIC for SDM.
