How to use an Analogue Channel with Tachometer Signals on the P8000

fa fa-file-text-o

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.

[Video] Creating speed signals for data with no tacho

fa fa-file-video-o

So you’ve got some noise and/or vibration data from a rotating machine, but no speed information. 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.

Watch the video to find out how…

There are tachometer signals available on the vehicle CAN-bus. Can I use these signals instead of connecting my own tachometer signal?

A simple question should have a simple answer and that answer is “No”.

As usual, however, life is never that simple. Continue reading There are tachometer signals available on the vehicle CAN-bus. Can I use these signals instead of connecting my own tachometer signal?

Importance of tachometer/keyphasor signal conditioning and its relationship to phase measurements

fa fa-file-text-o

This note describes the importance and setup of a keyphasor or tachometer signal for PROTOR Remote Monitoring Data Acquisition System (RMDAS) units. 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.
