2.2 CYLINDER PRESSURE SENSORS FOR ENGINE DEVELOPMENT
GH01D
TIGG2118A.01
The GH01D has the slimmest contour due to a M2 cable connector
and is a miniaturized and robust M3.5 sensor. This sensor is suitable
for mounting bores where access is a problem, a max. diameter of
3.5 mm makes it happen. 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.
