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

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.

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

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.
