2.2 CYLINDER PRESSURE SENSORS FOR ENGINE DEVELOPMENT
GU41D
TIGG2292A.01
GU41D is a durable M14 cylinder pressure sensor for engine development.
The sensor can be used with various fuels such as diesel, heavy
fuel oil or natural gas. It is equipped with a central preload element
that makes this sensor suitable for permanent non-stop operation.
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 engine. The sensor could be
equipped with SIC for SDM.
