When using an analogue channel input channel of a P8000, with a tachometer sensor, is it possible to utilise the tachometer processing functions as you would if you were using a tachometer input of the P8000?
For example could you display an RPM on an analogue channel?
When using an analogue channel it is possible to select, from the signal setup matrix, ‘Trigger Type’, with this option set to ‘Tacho’ and the ‘Trigger Level’ set to the voltage crossing threshold several features become available in terms of tachometer processing.
By selecting the above options the user will be able to use the ‘Digital Panel’ display type from the signal display and thus by selecting the ‘Speed’ option in the ‘Display Type’ drop down list an RPM will be available.

Surely that means you can’t analyse against speed or do any order analysis, right? Well, not quite!
The DATS Rotating Machinery option now comes with a tool to create speed v time data using your noise or vibration signals.

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. Continue reading How do I balance a shaft?

RMDAS units are provided with manual tachometer conditioning control. The note describes the control functions and there effect on the conditioned tachometer signal, it also describes the relationship between phase measurement and keyphasor triggering.
