Applications: The unit is combined with: A. External displacement sensor, for railway track vertical movement or crack development; B. External temperature sensor, for railway track variation monitoring. A vibration threshold trigger value can be set on a node switch, so that once the vibration threshold is reached by any object, such as a train passes by, a node can sample at 33Hz rate, and report to a gateway of maximum, minimum, average over a time interval.
