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 probe. This will allow the measurement of the shaft total runout*.
- If an electrical runout measurement is also required then an additional eddy current probe (also known as a proximity probe) is needed. This is a non contact probe and can be used in conjunction with the LVDT to measure the electrical runout only.
- A once per revolution tachometer is also required. This could be optical, proximity, magnetic and so on.
With these three sensors it is possible using the DATS Rotor Runout Measurement package to find both electrical and mechanical runout.
* Total runout is a composite tolerance including the effects of cylindricity and concentricity, co-axiality, straightness and parallelism along the axis.
