Some tests on electronique controle mesure equipment for axle load classification

Axle load estimation using piezoelectric cable sensors has been an active research area in recent years. This note describes the tests carried out on two axle load classifiers developed by the French from electronique controle mesure (ecm). The ARRB data logger was cited in conjunction with the ecm equipment to record the axle load data that was classified into two bins. The results point to the need for elaborate field calibration, even for a 'low cost' axle load classifier. It appears that the ecm equipment as tested could now be superseded by more accurate systems developed in France (a).
