When analyzing rotating shafts some terms are often confused. This post will attempt to explain the differences. So, what are vibration, torsional vibration and twist? What is Vibration? We

A long-standing customer brought along his power station turbine test rig so that we could give the P8000 hardware and DATS software a good workout. Here’s a video

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

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

In this article we will look at the basic steps needed to measure noise & vibration in rotating machines. We won’t look in great detail at some of

Creating a good quality tachometer signal is one of the hardest parts of analyzing rotating machinery. So what happens if we have missing tachometer pulses? The data looked

Knowing how to measure torsional vibration is of key importance in the area of vehicle development and refinement. The main contributory source is the engine where periodically occurring

Using Prosig’s P8000 series data acquisition system with DATS signal analysis software, torsional analysis (crank shaft jitter) was performed on an automotive engine attached to an engine dynamometer.

With shafts, gears and the like, the general method of determining the rotational speed is to use some form of tachometer or shaft encoder. These give out a

A shaft has been instrumented with two shaft encoders, one at each end. Each shaft encoder gives out a once/rev pulse and a 720 pulses/rev signal. Each signal

The measurement of torsional twist, or the twist angle, between two points along a shaft or through a gear train may be derived from a pair of tacho
