Vibration Testing

Response Dynamics Vibration Engineering, Inc.
We most often characterize a problem first and work from known conditions, and stay in “the known” as we proceed by making sense of what we observe as we move forward. We test and analyze the change in dynamics we are trying to create in real-time, on site, and often make changes to our experimental test plan on the fly as we discover how a system is actually behaving. In doing so we often get meaningful results from which we can make sound engineering decisions in a short time frame. We don't just make measurements and spit out data. We help identify the problem and propose solutions.

NI-9232, 3-Channel, 102.4 kS/s/channel, ±30 V, C Series Sound and Vibration Input Module
784397-01
Sound and Vibration
3-Channel, 102.4 kS/s/channel, ±30 V, C Series Sound and Vibration Input Module - The NI‑9232 can measure signals from integrated electronic piezoelectric (IEPE) and non‑IEPE sensors such as accelerometers, tachometers, and proximity probes. The NI‑9232 is also compatible with smart TEDS sensors. The NI‑9232 incorporates software-selectable AC/DC coupling, IEPE open/short detection, and IEPE signal conditioning. The input channels simultaneously measure signals. Each channel also has built-in anti-aliasing filters that automatically adjust to your sample rate. When used with NI software, this module provides processing functionality for condition monitoring such as frequency analysis and order tracking.

Infrasonic Array
Geosonic
-
An Infrasonic Array works like a sonic antenna, it is able to detect the magnitude and the source of sound waves. The Geosonic array is able to detect also pressure waves that the human ears can’t hear. A typical pressure wave is that generated by an explosion or by any physical phenomena (natural or human created) that generates an air pressure wave, which means that the Geosonic array can be used to detect a lot of phenomena, like:

Acoustic Calibrators
-
When you're ready to take noise measurements, it's strongly recommended that you perform a field calibration using an Acoustic Calibrator. You should calibrate your sound meter before you start to measure, and then once you've finished you should perform a reference check against the calibrator and make note of any drift that has occured. You can find out more about performing Field Calibrators by reading this post and watching a short video.
