Target applications
With the ability to set vibration limit values according to ISO 10816-3 (see "Limit values
based on ISO 10816 (Index 4534-4536)", page 33), the Multi Physics Box is ideal for
monitoring rotating components such as pumps, fans and motors.
Added to this are vibration, temperature and shock data, which enables condition deter‐
mination for additional applications. By recording condition indicators and machine
states, early maintenance cycles can therefore be carried out before failures and down‐
time occur with the resulting high costs.

As a result, maintenance intervals can be adapted to the actual maintenance require‐
ments. This results in reduced maintenance costs, higher machine availability, reduced
downtime/production loss costs, extended life cycles of machines and plants, and
increased production/product quality.
4.2.2 Status indicators
The LEDs indicate the current operational status of the Multi Physics Box. As shown in
figure 1, these light up the almost completely transparent seal to the outside at the
sides.
The different LED states are shown in table 1.

1With the Find device mode, it is possible to clearly identify the Multi Physics Box via the LEDs.
4.2.3 System architecture
The Multi Physics Box provides information for condition monitoring of machines and
processes.
For successful interpretation of conditions and incipient failures, ideally the threshold
of the condition change should be known or the sensor data should be analyzed. Both
on-premise and off-premise systems can be used for data analysis. Possible network
structures are listed in figure 3. An off-premise solution can be implemented via a
SIM1004 and via a secure SICK cloud connection using SICK LiveConnect. In the cloud,
services such as the Monitoring Box (www.sick.com/sick-monitoring-box) can be used.
Alternatively, the sensor can also be integrated into a PLC controller via an IO-Link
Master (e.g. SIG200) in order to save the data locally on a server.

4.3 Vibration analysis (Index 4474-4588)
The Multi Physics Box monitors the vibration of critical components in the time range
and in the frequency range.

1Time
2Frequency
4.3.1 Principle of operation
The sensor detects the acceleration via a MEMS element in the X, Y and Z direction.
For vibration monitoring, the Multi Physics Box does not display raw acceleration values
but rather statistical indication values. These values are calculated block by block in
an adjustable time window. The sensor needs processing time to calculate values in
the frequency range as well as in the time range. No acceleration values are recorded
during this time, as the sensor cannot process any other values.
table 2 indicates the typical processing time in relation to the block size. After process‐
ing, the indication values are updated and a new block is recorded. This process is
shown in figure 5. If a manual trigger (see "Trigger (Index 4474-4475)", page 15) is
set, the system waits for the next trigger signal. Likewise, the averaging of blocks (Index
4477, Subindex 5) influences the update rate of the vibration values. Index 4482 can
be used to determine whether updated indication values are available.

NOTICE
Changes in the vibration settings result in all set limit values and alarms being deleted.
Block length (Index 4477, Subindex 2)
The block length represents a compromise between the update rate of the characteris‐
tic values and the noise of these values. A shorter block length means more frequent
updating, a longer block length means higher averaging and thus lower noise of the
indication values. The block length can be set between 20 and 1,280ms, whereby the
maximum duration can only be used in single-axis mode.

40 20 60
20 10 30
NOTE
Single-axis operation reduces the processing time to approx. 20% of the block length.
Number of blocks for averaging (Index 4477, Subindex 4)
By averaging over several blocks, the noise of the indication values can be reduced
even further. However, this reduces the update rate of the frequency and time range
parameters.
Table 3: Example values for calculating the update rate
Block length [ms] Total block length [ms] Number of blocks for averag‐
ing
640 960 3
960ms (block length) x 3 (number of blocks) = 2,880ms (update rate)
As shown in the example calculation, the value is updated only after the defined
number of recorded blocks with the corresponding processing time. This means that
this value is updated every 2.9seconds. It should also be noted that averaging is only
useful if the vibration signal also remains uniform throughout the entire averaging time.

Data update counter (Index 4482)
The data update counter in Index 4482 can be used to see whether the indication
values have been updated. This counter is incremented by one each time new vibration
data is available in the time and frequency ranges. All influencing factors are taken into
account and the counter is only increased if new values are available in the indices. If,
for example, 5 blocks are taken into account for averaging, the data update counter is
only incremented after 5 blocks and the corresponding processing time.
Signal axis and axis mode (Index 4477, Subindex 1 and 3)
The Multi Physics Box also displays values in the frequency range (see "Vibration in the
frequency range", page 18) through a Fast Fourier transformation. This is calculated on
the vibration data of the signal axis selected via Subindex 3. If information of all 3 axes
is required, this can be implemented via the magnitude of the axes.
Magnitude =
If only one of the three axes is relevant for vibration monitoring, the sensor can be set
to single-axis operation via Subindex 1. In this case, all indication values are output
only for the axis selected in Subindex 3 (the values on the other axes are ’0’).
NOTE
The maximum block length of 1,280 ms can only be used in single-axis mode.
Signal type (Index 4477, Subindex 4)
The indication values can be calculated based on speed or acceleration values. This
selection is valid for the time range and the frequency range.
Indication values calculated based on speed weight low frequencies more heavily.
Indication values based on acceleration, on the other hand, weight higher frequencies
more heavily.
Phenomena that primarily cause vibration at frequencies up to 1,000Hz can be bet‐
ter observed with speed-based indication values. Acceleration-based indication values
should be used to detect phenomena that primarily cause higher-frequency vibrations.
Some examples are listed in table 4.
Table 4: Vibration speed and acceleration
Signal type Essential fre‐
quency range
Physical influence Application
Speed 10 ... 1,000Hz Kinetic energy and
inertia
Unbalance
Misalignment
Relaxation
Acceleration Up to 3,200Hz Dynamics and shock
forces
Mechanical wear, ball bear‐
ing damage
It should be noted that the speed-based indication values also heavily weight the
low-frequency noise. To obtain stable measured values when using this signal type,
the lower limit of the considered frequency range (Index 4478) should therefore be set
as high as possible. The minimum value for this limit is 10Hz with a block length of
640ms and is set automatically when changing to the Speed signal type. The minimum
values for this limit for the other block lengths are shown in table 5.

Bandpass filter (Index 4478)
Which frequency ranges are to be considered can be selected using a bandpass filter.
Restricting the frequency range can, depending on the application and the component
to be monitored, provide a more precise indication of an error.
If no bandpass filter is applied, the frequency range from 0to 3,200Hz is taken into
account. When using the “ISO10816limit values" (see "Limit values based on ISO
10816 (Index 4534-4536)", page 33), the monitored frequency range is limited to
10 ... 1,000Hz according to the specifications of the standard.
4.3.3 Trigger (Index 4474-4475)
Condition monitoring requires repeatable conditions and corresponding data quality. Only
with these two prerequisites can changes in condition over time and deviation over the
course of time be detected. In applications with continuous uniform speeds, such as
pumps or fans driven by asynchronous motors, this is usually the case. The vibration
should always remain the same, no matter at what point in time it is measured during
operation. This is not the case with dynamic, non-uniform movements such as punches,
presses or motors with changing loads. Here, the data must be recorded at a specific
point in time at which a constant vibration pattern is expected (e.g. always the same
point in time in the punching process).
NOTE
When using the trigger, the number of blocks for averaging (Index 4477 Subindex 4)
should be considered and set to 1 if necessary. With a block number of 4, for example,
the trigger must fire 4 times before the values are output.
Trigger settings (Index 4474)
Recording starts with an automatic trigger immediately after the boot process. The
data blocks and the evaluations then line up seamlessly and the indication values are
updated according to the total block length (see table 2, page 13). This is the factory
setting, which is suitable for uniform, permanent movements.
If, on the other hand, recording of data is to be started at an exactly defined time, it
can be triggered via an index or via pin 2. The selection of the trigger source (automatic,
index or pin 2) is done in Index 4474, Subindex 1. If required, this trigger can be
delayed by an adjustable time (Index 4474, Subindex 3).
Trigger via an ISDU
Index 4475 can be used to trigger by writing a 1 if trigger source ISDU is selected in
Index 4474, Subindex 1.

Trigger via pin 2 (Index 121)
Alternatively, pin 2 can be triggered by a falling or rising signal edge or both on the
hardware side. The setting via which a signal edge is to be triggered takes place in
4474, Subindex 2. At the same time, pin 2 in Index 121 must be configured as a trigger
signal (see "Configuration of digital outputs", page 44).
4.3.4 Activity detection (Index 4479-4480)
The sensor updates the indication values even when there is no vibration. In this case,
the indication values are calculated from the noise signal of the vibration sensor. Espe‐
cially the impulse factor (see "Vibration in time range (Index 4483-4539)", page 16)
can assume very high values, which can lead to misinterpretations of the machine
condition and undesired alarms.
An applied vibration can therefore be registered via activity detection. When the func‐
tion is used, Index 4480 outputs whether an activity is detected or not.
If no vibration is detected, all current indication values are set to 0, the minimum and
maximum values are not updated. This has the advantage that, for example, the limit
value of the impulse factor is not exceeded as long as no vibration is present. Activity
detection is based on the a-RMS magnitude value (or in single-axis mode, on the a-RMS
value of the selected axis). If the a-RMS value exceeds the “activity limit” set in Index
4470 Subindex 2, an activity is recognized as such. If the a-RMS value falls below the
limit value set in Subindex 3, no activity is detected accordingly.
4.3.5 Vibration in time range (Index 4483-4539)
The Multi Physics Box, as shown in section 4.3.1, provides indication values in the time
range calculated block by block. These values provide information about the vibration
intensity and the type of vibration signal.
A total of 9 statistical and vibration-specific values are provided for interpretation. The
mathematical basis of the indication values is described below. Which error cases and
effects can represent changes of the respective characteristic values is described in
section 9.3.
a-RMS (Index 4483-4485)
a-RMS stands for acceleration - Root Mean Square. The value, given in [g = 9.81m/s2], is
the effective value of the acceleration signal and a measure of the energy contained
in the vibration. It can be used to estimate the strength of the vibration. In general, it
can be assumed that the a-RMS value is more sensitive to changes in vibration above
1,000Hz than the v-RMS value.
v-RMS (Index 4486-4488)
In line with the a-RMS, the v-RMS (velocity - Root Mean Square) in [mm/s] represents
the effective value of the speed signal. This value is also a measure of the energy
contained in the vibration. Unlike the a-RMS, the v-RMS is more sensitive to changes in
vibration below 1,000Hz than the a-RMS.
Variance (Index 4489-4491)
The variance is a statistical measure that indicates how widely the signal values are
scattered around their mean value. In the context of vibration analysis, this is a meas‐
ure of the strength of a vibration analogous to the RMS value.

Skewness (Index 4491-4494)
Skewness is a statistical measure that indicates the asymmetry of the signal’s scatter
around its mean value. A change in Skewness indicates a fundamental change in the
mode of vibration.
Kurtosis (Index 4495-4497)
Kurtosis is a dimensionless parameter for the distribution of values in the acceleration
signal. The value can be used to estimate the type of vibration measured and thus
detect a change. For example, a white noise signal has a Kurtosis of 3, whereby a sine
wave has a Kurtosis of 1.5. An example is shown in figure 6, where pulses occurring in
the vibration are reflected in higher values of Kurtosis.

Peak to peak (Index 4498-4500)
The Peak to peak value indicates the range of raw acceleration and speed values. It is
calculated as the difference between the largest and the smallest value.
Shape factor (Index 4501-4503)
The Shape factor is defined as the ratio between the effective value of the signal and
the mean value of the absolute values of the signal. An increase in the Shape factor
indicates an increase in the amplitudes of harmonics in the signal.
Crest factor (Index 4504-4506)
The Crest factor is defined as the ratio of the Peak to peak value to the RMS value of the
signal. An increase in the Crest factor typically indicates the occurrence of pulsed signal
components.
Impulse factor (Index 4507-4509)
The impulse factor is the ratio of the Peak to peak raw values to the mean value
of the “Absolute raw values.” The value can be considered an indication of whether
brief pulses occur in the acceleration signal which are significantly stronger than the
permanent vibration.
For example, a pure sine wave has a impulse factor of 1.44. If a much stronger impulse
factor is measured for an expected sinusoidal vibration, this is an indication of pulsed
faults.

4.3.6 Vibration in the frequency range
Vibration data in the frequency range in many cases allow for a much more precise
identification of vibration causes than the previously discussed time range values.
For this purpose, the vibration signal is transmitted from the time to the frequency
range by means of FFT (Fast Fourier Transformation). The information of what are the
dominant frequencies in a vibration makes it possible to better understand the cause
of the vibration. For example, the vibration of an motor always contains vibrations with
frequencies corresponding to the motor speed, but can also contain vibrations caused
by the motor bearings or electronic components such as the rectifier, which contain
other frequencies.
The acceleration or speed spectrum of the vibration can be observed through the
frequency.
The analysis in the frequency range is based on the vibration values of one axis or
the sum signal of all 3 axes (magnitude). The selection is made via the settings of
the vibration analysis (see "Settings for vibration analysis (Index 4477, 4479, 4482,
4531)", page 12).
The settings for trigger, block length and number of blocks for averaging have the
same effect on vibration analysis in the frequency range. The bandpass filter must
also be taken into account, which can restrict the frequency range under consideration
between 0.78 and 3,200Hz.
The frequency resolution is calculated with 1/block length in seconds. It specifies
both the smallest measurable frequency and the minimum frequency spacing that
two vibration components must have in order to be distinguishable in the frequency
analysis.

As explained in section 4.3.2, the sensor can average the spectra of several data
blocks recorded in succession, and continue to process this averaged spectrum (to
output the spectrum or to detect the peaks in the spectrum). Averaging improves the
signal-to-noise ratio in the spectrum, but the output data is updated correspondingly
less frequently.
4.4 Temperature monitoring (Index 4352-4355)
Temperature changes in the application are measured via the back of the sensor hous‐
ing. The better the thermal diffusivity of the material on which the sensor is mounted,
the more accurate the measurement.
If the sensor is non-flush or there is an adapter plate with poor temperature conductiv‐
ity between the sensor and the machine, the influence of the self-heating of the sensor
is stronger and the measured value is less accurate. Observe section 6 here.
4.5 Shock (Index 4434–4448)
In addition to the vibration sensor for vibration, there is another MEMS-based vibration
sensor for shock detection in the Multi Physics Box.
With a measuring range of up to 200g, the maximum accelerations are measured in all
three axes, thus monitoring shock events.
