2.2 CYLINDER PRESSURE SENSORS FOR ENGINE DEVELOPMENT
GH15DKE
TIGG1595A.01 (A-type)
TIGG1597A.01 (B-type)
The GH15DKE is the elongated version of GH15DK and could be
used within oil and water jackets without the need of an adaptor
sleeve. It 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.
