1 Introduction

Welcome to INFRA V10, V11 and V12, Sigicom’s Geophones, built

for easy integration with the INFRA Field Monitoring System.

V10 measures vertically

V11 measures horizontally

V12 and V12R1 measures in all three dimensions.

V1x will be used as the common term for all geophones V10, V11 and

V12/V12R.

The figure below shows an example of the INFRA Field Monitoring

System setup:

one V12 geophone

one Air blast microphone

one Sound level meter

one Datalogger (INFRA Master, Mini or Micro) which

stores and communicates data.

Example of a setup of the INFRA Field Monitoring System

1 V12 and V12R are equivalent, except that V12R shall be mounted on the ceiling. In this

manual the term V12 refers to both V12 and V12R.


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

a comprehensive description of the INFRA Monitoring System, please

Possibility in post processing to apply frequency analysis of

transients.

Numerous of measurement standards are pre-programmed

into the sensor and can be selected as needed.

A LED indicates transient recording, overload and special

settings.


1.3 Unpacking and parts identification

Your INFRA V1x Geophone has been shipped in protective

packaging. Please keep the protective packaging for shipping your

device back to Sigicom when calibration is due.

Verify the package content with the following list:

V1x Geophone.

Foam (which protects your V1x from shock during

transportation).

Calibration Document.

Immediately report any damage or omissions to Sigicom.

Keep record of your instrument’s serial number. You will be asked to

give this number in any V1x related communication you may have

with Sigicom. Note! The V12 Geophone has three serial numbers, one

for each direction.


2 General 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.


3 Design 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.


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 data2 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)


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.


4 Configuration 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)


have the label parallel with the floor (readable from above)


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.

Example of V10 and V12 Geophone mounting.


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


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.

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 value4 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.

4.3 Quick Start V10 and V11

In this section, V1x means V10 or V11.

1. Connect your V1x Geophone with your INFRA Datalogger

by using any of the available INFRA Sensor Cables.

2. Start the Datalogger and wait for the initialization process to

complete.

3. Under the menu Nodes you’ll find your V1x unit as

GEO V1x-<serial.no>,

where GEO is the Customer string and <serial.no> is the

serial number.

4. Select GEO V1x-<serial.no> in order to set Standard (S01,

S02, etc.). Then, for the chosen standard, select

• Interval time

• Record time

• Threshold (level and ON/OFF).

Note! When performing a test or reference measurement,

make sure that the threshold is set to OFF. Otherwise

unnecessary transients will be recorded.

5. Activate REG ON, and the measurement will be initiated.

6. Note! First registration of interval data is delayed to

synchronize to the local time. The delay may last up to one

interval period. First presentation of data will then be delayed

up to two interval periods. Transient triggering and readout

of Live-values are available directly after activation of REG

ON.


4.4 Quick start V12

1. Connect your V12 Geophone with your INFRA Datalogger

by using any of the available INFRA Sensor Cables.

2. Start the Datalogger and wait for the initialization process to

complete.

3. Under the menu Nodes you’ll find your V12 unit as three

separate sensors:

GEO V12V-<serial.no>,

GEO V12L-<serial.no>,

GEO V12T-<serial.no>,

where GEO is the Customer string and <serial.no> is the

serial number.

4. For each of the three sensors, set Standard (S01, S02, etc.).

Then for the chosen standard select

• Interval time

• Record time

• Threshold (level and ON/OFF).

It is also possible to change the Customer string which in

some standards is used to select weighting type.

Note! When performing a test or reference measurement,

make sure that the threshold is set to OFF. Otherwise

unnecessary transients will be recorded.

5. Activate REG ON, and the measurement will be initiated.

6. Note! First registration of interval data is delayed to

synchronize to the local time. The delay may last up to one

interval period. First presentation of data will then be delayed

up to two interval periods. Transient triggering and readout

of Live-values are available directly after activation of REG

ON.


4.5 The LED

V1x has a red LED which indicates different events and states.

V10 (its LED marked with the red arrow).

5 Consider this

V1x Geophone can be used and stored in a wide range of

ambient temperatures. However, allow your V1x Geophone

ample time to adjust to abrupt temperature changes.

Whenever the V1x Geophone is shipped, care should be

taken in repackaging using the original packaging provided

Appendix D Example of using a weighting standard

Suppose we have configured:

Standard 18, DIN 4150-3, with Zeile 1 (selected according to

section 4.2.5).

Threshold level = 20 mm/s.

The standard DIN 4150-3 is described with the graph:

Figure D1. Standard DIN 4150-3 with the limits for Zeile 1 - 3 (Line 1 - 3)

and the weighting depends directly on these lines.

As written in section 4.2.5, the reference frequency range is: <10 Hz. In this

example we study Zeile 1 (Line 1), which for example allows

2.0 times higher velocities at 50 Hz compared to frequencies <10 Hz

2.5 times higher velocities at 100 Hz compared to frequencies <10 Hz

The limits in figure I1 lead to the weighting curves in figures I2 – I4, which

are implemented in the firmware of INFRA C12.


Figure I2. The weighting of the measured signal, made by the

C12 firmware when configured with standard DIN 4150-3, Zeile 1.

So, in this example, a maximum vibration level detected as

35 mm/s

50.0 Hz

will be used as

17.5 mm/s

50.0 Hz

These two points are illustrated with the red stars in Figure I1.

Note! This means that a trigger event will not occur in this example,

although 35 mm/s is measured and threshold level = 20 mm/s.
