There are two well-established approaches to measuring forces: quartz piezoelectric sensor technology, and the strain gauge method. For dynamic force measurements (when the forces to be measured move or change very quickly), quartz piezoelectric technology shows unrivaled advantages. Weigh In Motion applications are a good example of this: vehicles passing over the sensors at speeds of 100 km/h or more generate very fast force impacts, and the sensor can be exposed to loads of several tonnes within a matter of milliseconds. This is just one of many reasons which prove that quartz piezoelectric technology offers far greater benefits than the strain gauge method. What are the precise reasons for preferring quartz piezoelectric technology over strain gauges in a WIM system?
