MARIN is ready for the future with the all new MMS2


In 2016, MARIN launched MARIN


Measurement System 2 (MMS2), which represents a major improvement. The total number of measurement channels has increased (now over 200 channels), the available sampling rates are higher (up to 200 kHz) and the signal quality is improved. But, more importantly, we have implemented several new developments in the system.


MMS2 conditioning modules


By placing the conditioning part of MMS2 in the test model, cable lengths, as well as the total number of cables from the model to the carriage, have been reduced. The conditioning system recognises transducers with Transducer Electronic Data Sheets (TEDS) and automatically selects conditio ning and calibration information, which reduces the


number of mistakes in the measurement system setup.


Additionally, we improved the synchronisation of MMS2 with other systems involved in the measurement process, using IRIG-B time synchronisation. Furthermore, a new advanced self-describing file format has been imple- mented based on HDF5.

We have also introduced three new components that work in close collaboration with MMS2. These three elements are:


1. Technical Data Management System (TDMS): In combination with MMS2, MARIN uses a database system to store all the relevant metadata and information associated with the measurement process. This will improve the consolidation and traceability of all the information and data in a project.


2. Sensor & Calibration DataBase (SCDB): This database contains the information of all the transducers at MARIN and the calibrations that are performed with these transducers. This again improves consolidation and traceability.


3. Measurement Analyser: This software tool checks the measurements immediately after they have been taken for any timing issues and quality aspects. Furthermore, it combines measurements from different systems to MARIN’s new file format.


We are confident that the new MMS2 enables us to accommodate the sophisticated measurement tasks that are needed both now and for the foreseeable future.
