2.2 CYLINDER PRESSURE SENSORS FOR ENGINE DEVELOPMENT
GU22C
TIGG1073A.01
The GU22C is a 6.2 mm plug-type sensor for precise thermodynamic
analysis which fulfills reference class requirements when used in combination
with the PH04 flame arrestor. 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
the mounting bore and the sensor housing. A thermo protection can
improve the cyclic drift down below ± 0.4 bar. The sensor is equipped
with built in SID for SDM.
