capturing measurements during production engine development
programs. This facilitates a rapid and thorough validation of
engine computer model development. Our capabilities, expertise
and proven application of these measurement tools can assist
any engine manufacturer or engine component developer to gain
a fundamental understanding of actual phenomena that takes
place within an engine. From temperatures or pressures to strain
or displacement, we have the technology to make the
measurements a reliable reality.
