WP 2 - Sensors concept and design 

Lead beneficiary: NORSK ELEKTRO OPTIKK AS - Norway

Period: month 1-10

Obiectives

The main objective of this WP is to realise a design of laser based gas sensors that can be adapted to different
applications and measurement setups by using a modular concept that can be used in a number of different
configurations. Two different measurement techniques will be studied:
• The GASMAS technique that is specifically intended for non-transparent samples (patented by GPX)
• The LPRO technique that is specifically intended for transparent samples
Variants of traditional in-line optical designs for transparent samples

Description of work and role of partners

Task 2.1: Conceptual prestudy 
Based on inputs from WP1 a prestudy will be made with existing laboratory instrumentation at GPX and
with existing prototypes instrumentation at Lpro. The concept prestudy will evaluate different measurement
approaches of the target sample. Optimization of the measurement after the limitations from the specific case,
such as a given measurement time and information about the production way will be included.

Task 2.2: System Architecture
Based on the input from Task 2.1.a the system architecture will be determined taking the modular design into
account. To save time and cost the work will be based on the technology platform developed by NEO and CNR,
which are suitable for both the GASMAS and Lpro technique and the traditional inline technique. The task will
include the best choice of measurements technique for the applications defined in WP1, according to package
type.

Task 2.3: Development and realization of offline sensor Type 1
This task will include electronic, optical and mechanical design of the modules, based on the GASMAS
configuration, that will constitute a complete gas sensor based on the system architecture from task 2.2 for the
applications specified in WP 1

Task 2.4: Development and realization of offline sensor Type 2
This task will include electronic, optical and mechanical design of the modules, based on the traditional
configuration that will constitute a complete gas sensor based on the system architecture from task 2.2b for the
applications specified in WP 1.

Task 2.5: Definition and design of inline sensor 
Adaption of the design made in task 2.3 and 2.4 making the sensors suitable for inline applications, including
adaption of response time.

Task 2.6: Laboratory tests and calibration 
This task will include laboratory tests of the completed prototypes to verify that the expected performance has
been met.
The second part of this task is to develop a reliable and simple to use calibration techniques that will allow the
end user to verify that the instrument is working according to specifications.
