2.2 CYLINDER PRESSURE SENSORS FOR ENGINE DEVELOPMENT
GA16P
TIGG1924A.01
The GA16P is a derivate of the GH14P sensor. It can be used in
combination with glow-plug adaptors with sensor bores of 4.4 mm in
diesel engines. The GA16P comes with an M3 connector which allows
the smallest installation tool clearance diameters. The Double-Shell™
design decouples the piezoelectric elements from negative influences
of mechanical stresses which can occur due to the mounting of the
sensor into the adaptor or engine. The sensor could be equipped
with SIC for SDM.
