Introduction:
This module measures and analyzes mechanical
vibrations and variable AC and DC power. It groups
all the measurements of the DSP Logger Expert on
all its inputs, allowing the user to select vibration
measurements with pre-configured settings for
expert analysis or configurations designed to search
for other sources of or complex analyses of
vibrations.
The firmware contained in Option 1 of the DSP
Logger Expert is selected with the arrow keys or
directly with the 1 key.
Entering this firmware shows two options on the
screen, as shown in the following display.

Quick Measurement:
This firmware contains 3 types of vibration analysis,
which are performed fully automatically.
It enables a simple load of the machine parameters
to be analyzed, allowing the system to capture,
analyze, and monitor vibration levels associated with
mechanical failures.
Bearing Analysis:
This tool defines an accurate calculation of the state
and condition of the bearing to test for bearing
and/or lubrication failure.
To do this, you must enter the estimated RPM of the
machine.
Spike Energy Level:
This tool defines an enveloping measurement value
of the Energy Spike ® analyzing bearing condition
and the values of bearing failure frequencies.
These calculations are performed automatically,
requiring the value of the estimated RPM, the model,
and the manufacturer of the bearing.

ISO 10816 Measurements:
This measurement tool performs an analysis of
machine speed, adjusting the settings to the
requirements of ISO 10816 and evaluating the
condition of the states covered by the rule.
The input data that this tool requires involves the
classification of the machine in the norm groups.
In addition to the input of the RPM value, the meter
system expert shows vibrational levels for the
balancing, alignment, and rotation of the machine
backlash.
Home:
When entering the quick measurement by the icon
you will enter the settings window:

Input parameters:
The parameter display indicates the status of the six
(6) inputs of the DSP Logger Expert according to the
connected and disconnected sensors.
The entries are grouped into 3 (three) groups for
Channel A and Channel B, each taking the X, Y, or Z
direction.
Red indicates no sensor signal.
Green confirms that the sensor and cable are in
good condition.
The parameter window displays all the fields
necessary for analysis calculations.
The only required field for the use of the tools is the
RPM.
The parameter window is divided into two (2)
segments. The left corresponds to Sensor 1, and
the right corresponds to Sensor 2.

The input bearing manufacturer can be viewed by
selecting the list that has the system and factory
preloaded.
Model selection is performed via a selection of all the
bearings corresponding to the selected
manufacturer.
You can enter the bearing model by placing the first
number or the complete number of the bearing, so
the position will be close to or an accurate bearing.

Parameters copy:
The parameter window contains a tool to copy the
parameters entered in sensor A or B.
The parameters that are not copied from one sensor
to the other bear manufacturer and model data.
When activated, the system will request the copy
from one sensor to the other.
Class ISO10816:
ISO class is selected depending on the measuring
machine.
Part 3: Industrial machines with nominal power
above 15 kW and speeds between 120 and 15000
RPM.
The criteria for the vibration of this standard apply to
a set of machines with a capacity exceeding 15 kW
and a speed between 120 RPM and 15,000 RPM.
The criteria are only applicable to vibrations
produced by the machine itself and not to vibrations
that are transmitted to the machine from external
sources. The effective value (RMS) vibration velocity
is used to determine the condition of the machine.

Bearing Analyzer:
The first step is the entry of the parameters in sensor
1 and/or 2.
Once the parameters load, press F4 to activate
NEXT.
The menu functions F1 to F4 will change to the next
options.
Function F1 allows you to select analysis options.
This is done by pressing the F1
key until you reach the desired
option.

Once there, confirm with the ENTER key.
Once confirmed, the measurement screen will be
presented online as measured from the first moment
of visualization.
The Bearing Analysis screen, shown above,
measures the input channel to the RMS value. The
red HOLD frame on the right keeps the maximum
value detected from the start of measurement or
since reset to zero using the #key.

The spectral measurement corresponds to an
acceleration range of 800 lines with a maximum
frequency of 10 kHz.
On this configuration, the system calculates the
state of bearing and lubrication.
Each of these indicators shows a different status:
Bearing Lubrication
ACEPTABLE ACCEPTABLE
ACCEPTABLE CAUTION
CAUTION EMERGENCY

The measurement is presented online.
To stop the measurement, press the
ESCAPE button.
To restart the measurement, press the
ENTER button.

Measurement stopped (flashing indicator)
Continuous measurement process
Additional indicators:
The following values are shown on the right side of
the screen:
0.P.: 0-Peak scalar value.
PP: Peak-Peak scalar value.
F.C.: Crest Factor scalar value.
Also shown are four (4) detected maximum peaks in
the spectrum, which indicate amplitude and
frequency.
The cursor function is activated with 1 key.
The indication appears for amplitude and frequency.

The graph shows the values and status of the fault
frequencies:
The bearings are composed of several clearly
differentiated components: inner race, balls or
rollers, cage, and outer race. The deterioration of
each of these elements will generate one or more
characteristic frequencies in the spectrums, allowing
for quick and easy identification. The four possible
frequencies of bearing damage are:
BPFO (Ball pass frequency of the outer race): The
physical number of balls or rollers that go through a
point outside the track each time the axis makes a
full rotation.
BPFI (Ball pass frequency of the inner race): The
physical number of balls or rollers that go through a
point inside track each time the axis makes a full
rotation.
BSF (Ball spin frequency):
The physical number of turns made by a ball bearing
each time the axis makes a full rotation.
