There are a large number of available sensor types, and up to 16 nodes
can be connected to one Datalogger.
Note! V12 consists of three nodes. Maximum 16 nodes can be
connected to each Datalogger, however to ensure smooth operations it
is recommended not to exceed nine nodes per Datalogger. Therefore a
maximum of three V12s may be connected per Datalogger.
INFRA Net is used to post-process and analyze all measured data. For

2General description
The V1x Geophone is a precision sensor to be integrated with INFRA
Field Monitoring System. It measures vibration level in the
dimensions:
V10 measures vertically
V11 measures horizontally
V12 measures in all three dimensions.
The V1x Geophone is to be connected to the INFRA Field Monitoring
System by any of the available INFRA Sensor Cables, which supplies
your V1x Geophone with both electrical power and all necessary
communication.
Within INFRA Field Monitoring System it is possible to measure a
number of parameters simultaneously in addition to the vibration level
measurements, for example:
noise level
air blast
dust (particle concentration)
wind speed and wind direction
rain intensity
air temperature
air humidity
atmospheric pressure
etc.

3Design features
3.1 Measurement standards
The V1x Geophone contains a number of pre-defined measurement
standards. Each of them filters the frequency curve according to the
selected standard. The standard also decides the level range. See
section 4.2.1 for a complete list of the standards that can be selected.
3.2 Measurement Data
Interval and transient data are recorded simultaneously within your
V1x Geophone, and will be stored by your connected Datalogger in
interval files and transient files, respectively. For traceability of the
registered data, all data files have an extensive header where all
necessary meta-data is saved, for example serial number and
calibration date, selected standard, threshold level etc.
3.2.1 Interval data
Interval data is normally the maximum vibration level over each time
interval and is sent to the Datalogger which saves it in an interval file.
The interval data are filtered according to the selected standard.
Instead of taking the maximum level of the measured values, some
standards calculate RMS value before extracting the maximum.
Attached to the saved data in the interval file, there is information
about overload, invalid data and registration status changes.

10 Copyright ©Sigicom AB
3.2.2 Transient data
The V1x Geophone records transient data after a trigger event. The
trigger event happens when any of the following is valid:
The vibration level becomes larger than the threshold level
(threshold must be active).
Another sensor connected to the same Datalogger triggers.
The operator of the Datalogger triggers manually.
The transient data is anti-alias filtered, but not further filtered
digitally. Instead, it is possible to apply any of the available standards
on the recorded transient in INFRA Net. Pre-trig is always 1 second,
and recording post-trig length is adjustable between 1 and 40 seconds.
Recording limitations:
The transient memory in V1x has a length of 42 seconds. If
the recording length is set longer than 20 seconds, each
recorded transient must be transferred to the Datalogger
before a new transient can be recorded. When the recording
length is maximum 20 s, the transient memory is split into
two or more transient files. This enables more than one
transient file to be recorded, without latency, before the V1x-
memory becomes temporarily full.
Transfer capabilities to the Datalogger are set to enable long
cables and low power consumption. Approximately 0.3 - 0.6
s of vibration level data are transferred per second. This
means for example that if you have set transient files to 40
seconds, there must be at least 70 seconds between the
transients for V10 and V11, and 3.5 minutes between the
transients for V12. Otherwise cannot transients be recorded
because the memory is occupied by the previous transient
(which is being transferred to the Datalogger).
NOTE! The transfer times above is per sensor which means
that you must multiply the times with the number of sensors
connected to the same Datalogger. A solution to this
limitation is to use more than one Datalogger.

3.2.3 Frequency detection and weighting
Certain standards have a second channel of interval data containing
the frequency of the maximal vibration level during the interval time.
Which standards having this second channel are written in the table of
International standards in section 4.2. These standards may also
include a number of frequency weighting models, which re-calculates
interval data according to the weighting algorithm:
1. Detect all zero crossings in the vibration level signal
2. For each zero crossing, calculate the frequency based on the
number of samples since last zero crossing
3. Depending of weighting model, recalculate the maximum
vibration level value within the half period
4. Check if the new weighted value is larger than last saved
maximum in the interval
Each weighting model recalculates the vibration level signal as stated
in its standard.
More facts about standards with weighting model:
Transient files are not affected by the weighting.
The trigger system uses weighted data, see a descriptive
example in Appendix D.
Note! The trigger event is delayed to the zero crossing after
the signal maximum.
Direct SMS messages from the Datalogger send weighted
vibration level values.
X85 Alarm Beacon uses weighted vibration level values for
the decision when to trigger an alarm.
LIVE, LAST and EVENT data
2
in the Datalogger display
shows weighted vibration level values.
Live mode in INFRA Net shows weighted vibration level
values.
The log file still contains the unweighted vibration level, and
considers only post-trig data.
2
LIVE (=current value), LAST (= last interval data) and EVENT (= transient data)

12 Copyright ©Sigicom AB
Description of how to select weighting model is described in section
4.2.5.
Note! The Vibration level / Frequency interval diagram in INFRA Net
is plotted with unweighted vibration level. This implies that the
vibration level values are “anti-weighted”, based on the frequency and
used weighting model before they are plotted.
3.3 Display device
Data is presented and post-processed by the web application
INFRA Net.

4Configuration and operation
4.1 Mounting
The V1x Geophone shall be mounted according to:
V10 shall be mounted either on the wall or on the floor, and
have the label parallel with the wall (readable from the side)
V11 shall be mounted either on the wall or on the floor, and
have the label parallel with the floor (readable from above)
V12 shall be mounted either on the wall or on the floor, and
have the label parallel with the floor (readable from above)
V12R shall be mounted in the ceiling and have the label
parallel with the ceiling (readable from below)
Note! For correct measuring results, the mounting angle of the V1x
Geophone must not exceed 5º relative to the reference plane.
Note! To facilitate proper communication in electrically harsh
environments, the metallic enclosure must not be in contact with any
kind of conductive surfaces (the sensor feet are isolated). All cable
junctions touching any metal or the ground shall be protected by
vulcanized tape.

4.2 Parameters
4.2.1 International standard selection
The table below contains all available measurement standards included. As
new countries with their local measurement standards (blasting, human
comfort and sensitive equipment) are added, some standards exist on only
one of the defined sales regions:
NO: Nordic countries
EU: European countries (except the Nordic countries)
IN: All countries outside Europe
This is due for V12, from firmware version 2.0. V10 and V11 will
have the same standards as V12 for the Nordic countries (NO).
Explanations for the table below:
Frequency: Tells whether the standard has a second interval channel/file
with frequency values. 0.5Hz resolution.
Weighting: Standard can be set, or is permanently set, to use frequency
weighting of interval values and trigger levels. This is implemented in
different ways for the various standards.
Note! All filters mentioned below are implemented as time continuous digital
filters, calculated in real-time on each sample (4096Hz).
1. “No”
No extra filtering in the pass-band between the frequency limits stated
in the standard definition. Geophone compensation filters may exist
when the standard is stated to have its low frequency limit below the
natural resonance frequency of the geophone.
2. “ISO2631-2 type”
Used in human comfort standards only. Implemented by inserting a
high-pass filter (single pole at 5.6 Hz) prior to the RMS detector.
3. “Norwegian type”
Used in some Norwegian standards. Implemented by more complex

Copyright ©Sigicom AB
15
skewing filters prior to the peak/trigger detectors, as described in the
specific Norwegian standards (NS8141:2012 and NS8141:2013).
4. “Discrete frequency type”
These weighting characteristics needs to be implemented in another way
compared to the ones above, and are instead calculated using the
frequency and unweighted peak value, calculated after every zero
crossing.

The desired standard is selected using either:
Datalogger.
INFRA Net –Remote control.
Note! Each standard has its own unique parameter setting
Interval time
Threshold
Recording time
Customer string
meaning that they are set individually for each standard. When another
standard is selected, these parameters need to be reviewed.
Additional and updated standards may be added later through software
upgrades. For upgrade of software, the V1x Geophone must be sent to
Sigicom or other authorized agent. Some standards have been
removed, see Appendix E Removed standards.

4.2.2 Interval time
The interval time is the parameter that decides how often the
maximum value
4
is stored. The maximum value of each interval is
saved to an interval file. The interval time can be selected to any of the
values:
5, 6, 10, 15, 20, 30 seconds
1, 2, 4, 5, 6, 10, 15, 20 minutes
The default value of the interval time is 2 minutes.
4.2.3 Threshold
If the measured vibration level becomes larger than the
threshold level, a Trigger event happens, implying that the
measured signal is recorded in a transient file.
5
The threshold can be set to OFF, which means that the
threshold level has no effect on the system.
Even if threshold is set to OFF, other sensors within the same
INFRA system may trigger a recording on all sensors in its
INFRA system.
4.2.4 Record time
This is the length of the recorded transient file described in section
3.2. It can be selected to any of the values:
1, 2, 3, 4, 5, 6, 8, 10, 16, 20, 25, 30, 40 seconds
The default value is 2 seconds.
4
Velocity or acceleration
5
All sensor nodes connected to the same Datalogger will simultaneously start a
transient recording. This feature called bus trigger can be disabled.

4.2.5 Customer string
The Customer string is a four character string that can be changed.
The default string is “GEO “. The intention is here that you can use
this as a description of your measurement.
For some standards the last two characters in the Customer string are
used to set a weighting model of that standard, see the tables below.
The first two characters are free to use as you wish (marked with ** in
the tables).
Note! If the customer string is set to something else, no weighting is
performed. This is not due for Standard 40 (Arrêté du 1994), for
which weighting always is active.
