2.2 CYLINDER PRESSURE SENSORS FOR ENGINE DEVELOPMENT
GU22CK
TIGG1355A.01
The GU22CK is an accurate and robust 6.2 mm plug-type sensor. It is
based on a well established design concept that allows high accuracy.
It has thermally optimized piezoelectric elements and no influence
from the mounting bore on the pressure signal due to minimized
mechanical contact between mounting bore and the sensor housing.
A thermo protection can improve the cyclic drift down below ± 0.3 bar.
The sensor is equipped with built in SID for SDM.
