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. |
