Terminology
Measurement interface (MI)
Nmas supports multiple signal and sensor connections. Some of these are
sensors but nmas has no limitation of the input type. All data entered to nmas
comes from
Measurement Interface.
Examples of
mesurement intefaces
:
•
acceleration sensor (IEPE type)
•
pulse sensor
•
pressure sensor
•
oil particle counter
•
modbus interface
•
digital sensor
Signal
Some
measurement interfaces
provide timebase data. This data is described as
signal
in nmas.
Signal
is sample of data during limited time frame.
Signal
is
used for further analysis and can be stored for later analysis.
Signal
is typical
for acceleration and voltage inputs.
Picture 1: Signal from acceleration sensor.
Figure
All trend data is handled as
figures
.
Figures
are single number values
representing data from measurement interface. User can attach multiple
figures
to same
signal
. Typically
figures
have relation to physical quantities.
At least one
figure
should be linked to every
measurement interface
.
Figure
names are used in data views and reporting.
