2.2 CYLINDER PRESSURE SENSORS FOR ENGINE DEVELOPMENT
GH15D
TIGG1349B.01
The GH15D has the slimmest contour due to a M3 cable connector
and allows very precise thermodynamic measurements with a sensor
of size M5. This is realized by 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.
Using a thermo protection like PH08 can improve the cyclic drift by
0.3 bar. The sensor is equipped with built in SID for SDM.
