2.1 PRODUCT SELECTION GUIDE
How to choose the right sensor and accessory
Each measurement task and application requires a specific
solution to achieve maximum precision and high quality
data. AVL offers a complete range of pressure sensors and
accessories for combustion analysis. In order to make the
choice of the right equipment more convenient AVL offers
several tools.
The product selection guide starts with a list of common
questions and problems a customer typically faces in
the decision making process when selecting a sensor.
Depending on how the question is answered a page
reference within the chapter is given which can act as a
starting point in selecting the correct pressure sensor.
QUESTION ANSWER PAGE
“How can sensors be quickly classified
according to their performance and usability?”
The use and interpretation of icons
“How can sensors be quickly classified according to
their performance and usability?” The icons used in the
datasheets and in the comparison chart help to classify a
sensor quickly according to its strengths and key features.
There are two different types of icons. The first type
‘strength’ indicates how well a sensor is suitable for a
specific measurement task or application field. Further
the icons for strength are rated from one to three stars
(standard, good, excellent suitability). The second type
“key feature” gives information about the special
technical components or design features.
Toughness / knock applications
Purpose: Specially designed to
withstand under extreme and harsh
conditions.
Examples: Analysis of knocking combustion,
operation under high engine
loads and supercharged engines
Precision / thermodynamic analysis
Purpose: Highly accurate measurements
for critical thermodynamic
analysis.
Examples: Measurements for heat
release and friction loss calculations
Durability / endurance testing
Purpose: Permanent, non-stop
monitoring.
Examples: Onboard monitoring of
large marine or stationary engines
