WebDAQ 504 Integrate signal for velocity/displacement

[James S]

Getting my accelerometer channels setup with the WebDAQ 504 was easy. I have not been able to find a way to integrate the acceleration signal to get to a velocity or double integrate to get displacement. Vibration specs we encounter are defined in velocity (in/s) and displacement (mils). Is there a way to do this with the WebDAQ 504?

Hello @James S.

WebDAQ's Dashboard displays time domain data on a strip chart, and frequency domain data on an FFT display.  You will need to save the time domain data and post process the data for velocity and displacement in a third-party application, i.e. LabVIEW, MATLAB, custom programming code.

Hello @James S,

This is exactly what i need also.. Can this be done in real time?

So present the "overall vibration level" in real time i mean?

Hello @Koos.

In the WebDAQ application, with the WebDAQ 504, a user can select the signal type (Voltage, Acceleration, Sound Pressure, Velocity, and Force) in the Job Editor.

The Dashboard displays the time domain data and frequency domain data separately. 

 

Users may choose to develop a custom application for their own requirements, in which case we suggest using the WebDAQ REST API.  The WebDAQ REST API includes example programs developed with Python, C#, VB, and NI LabVIEW. Users are encouraged to run the examples to become familiar with the WebDAQ hardware and REST API.  WebDAQ REST API example programs are available for download here:
