2.2 CYLINDER PRESSURE SENSORS FOR ENGINE DEVELOPMENT
GH15DK
TIGG1383B.01
The GH15DK has the slimmest contour due to a M3 cable connector
and is an accurate and robust M5 sensor especially suited for supercharged
engines with high specific output. It has thermally optimized
piezoelectric crystal elements and the special Double Shell™ design.
It decouples the piezoelectric elements from negative influences
of mechanical stresses which can occur due to the mounting of the
sensor into the engine. Additionally it has an improved membrane
material and geometry. This makes the sensor more robust suitable as
the standard solution for research and development work with perfect
trade off between accuracy and robustness. Using a thermo protection
like PH08 can improve the cyclic drift by 0.4 bar. The sensor is
equipped with built in SID for SDM.
