The Sensors

The instrumentation at the NAPTF consists of over a thousand sensors of various types distributed among the nine test items. Sensors are divided into static sensors (which collect data on an hourly basis) and dynamic gages (which are triggered by vehicle movements). For a listing of sensor locations, click one of the lists below:
