Applications

Using the GP1 to collect field information.

The GP1 is a rugged easy to use instrument that is equally at home in a lab or in the field. In field operations the instrument can collect more than 35 days of dynamic data related to motion, shocks, impacts, vibrations, and accelerations. The GP1 will record both summary data and waveform data making it an ideal instrument for discovering basic facts as well as getting the information that supports a detailed analysis.

In this example a wooden bridge pier was monitored to measure its response in relation to extreme loads and to confirm when other loads crossed. The GP1 was set up to record summary data and waveform data.

The summary data provides a quick overview of the highlights such as what the maximum, minimum, and average axis acceleration inputs were and when they occurred.

The summary data is a fast way to get an overview of exactly what happened and when.

In this example the summary pane is showing when the pier was loaded, the magnitude of the acceleration responses and how many times the pier was loaded during the evaluation period.

The summary data can be combined and measured to identify key associations and events. In this example the y-axis input is being compared to the overall pier acceleration to determine which axis showed the greatest movement.

The GP1's summary mode can calculate and report up to 21 different measurements, these measurements take the guesswork out of trying to understand what occurred.

In addition to the calculated values that are generated by the summary mode, the GP1 also records acceleration waveforms; acceleration waveforms are a compilation of individual acceleration samples taken every 10 milliseconds and then stitched together to describe the characteristics of the motion. The waveform files show the details and nuances of the motion and displays exactly what occurred, the ability to visualize dynamic signatures helps the user see and compare complex relationships. In this example an event is being analyzed; the three-axis inputs are being compared to each other.

The software that comes with the GP1 has an export to csv function that lets the user export the summary and detail data out to other analysis packages.

The GP1 is an ideal field instrument; it is quick to set up and easy to use. The instrument measures and records the dynamic inputs that it is exposed to. The GP1 provides the field data that professionals need to know.
