The name and symbol are used to identify the sensor.
The metadata are listed below the symbol:
■
ID
■
machine type
■
sensor type
■
installation date
■
date of last KPIs received
■
date of last raw data received.
The sensors transmit the KPIs every four hours, which means that
six KPI data samples are transmitted per day. If a dataset is not trans-
mitted, the system interpolates the diagram on the basis of earlier
and later values. Using the [
Toggle Markers
] button, the graph can
be switched to show the points in time when the KPIs were received
by the sensor.
Optionally, requests for KPIs and raw data can be initiated directly
via the OPTIME app and OPTIME dashboard.
KPIs
The [
ISO/DeMod/Temp
] tab shows graphs for the basic data on
condition monitoring, the ISO value (standardised vibration inten-
sity to ISO 10816), the DeMod value (demodulation) and the
temperature.
The [
Excess Kurtosis High/Low
] tab shows graphs for the excess
kurtosis value in two different frequency ranges.
The [
RMS Upper Band/RMS Lower Band
] tab shows the RMS value of
the vibration data, also for two different frequency ranges.
The [
Anomaly Score
] tab contains graphs based on an algorithm
developed specially by Schaeffler. This parameter shows a signifi-
cantly lower dependency on operating parameters such as speed
and power.
