Prosig was contracted by Imperial Electric in Akron, Ohio to integrate a system for end of line vibration test for electric motors they manufacture. The requirement was to qualify motors under…
Our articles on how to measure resonance and natural frequency are always amongst our most popular posts. This isn't surprising considering what an important concept this is to the measurement…
In this post we will first look at how to process data from rotating machinery. Then we will focus on shaft or gear train twist. Let's look at 3 different…
What sample rate should I use if I am measuring whole body vibration? Strict ISO8041 compliance imposes a minimum sample rate of 900 samples per second. This ensures the amplitude…
In the process of looking at some order data, a question about the accuracy of the measurement of the signal level of discrete frequency signals which were close to the general noise level. To answer this question, a small DATS worksheet was created which generated 2 signals. The first signal was a 35 Hz sinusoid which, by itself the spectrum level was measured to be approximately -9 dB (ref 1 V) as seen in Figure 1.
The DATS Rotor Runout Measurement package can be used on any shaft where the following probes are available... A LVDT (Linear Variable Differential Transformer) probe. This is basically a contact…

“How do I balance a shaft?” seems like a fairly straightforward question, but there are a number of things that we need to understand first. Here we look at a number of key concepts that need to be understood in order perform balancing.
Well broadly speaking to balance a shaft, mass must be added or removed at certain angles. The concept being that the centre of gravity and rotational centre of the shaft will be equal when the shaft is balanced. (more…)

The P8012, P8020 & P8048 can all be fitted with the 8440 CAN-bus/GPS card. Setting up the P8000 to capture CAN-bus data is extremely simple. In the following video, James…
Are you interested in measuring torsional vibration? Need to measure shaft twist? Worried about rotational jitter? Don't worry, we've got it covered. Here we have gathered together our most popular…
We're often asked what is the difference between microphone types; free field, diffuse field and pressure. For a run-of-the-mill ½ inch microphone the short answer is nothing. However the long…
