2.2 CYLINDER PRESSURE SENSORS FOR ENGINE DEVELOPMENT
GR15D
TIGG1977A.01
The GR15D has the slimmest contour due to a M3 cable connector
and is an accurate and robust M5 sensor especially suited for engines
with high vibration. It has thermally optimized piezoelectric elements.
In addition to this it has an improved internal design of the measurement
cell and charge output. Using a thermo protection like PH08 can
improve the cyclic drift by 0.4 bar. The sensor could be equipped with
SIC for SDM.
