1.1 General Information

The FS22 - Industrial BraggMETER SI with real time
embedded Smart Peak Detection (SPD) is a continuous
swept laser scanning interrogator specifically designed to
interrogate Fiber Bragg Grating (FBG) based sensors in
industrial environments.

BraggMETER interrogators include a NIST traceable
wavelength reference that provides continuous calibra
tion to ensure system accuracy over long term operation.
The high dynamic range and high output power com
bined with the Smart Peak Detection (SPD) allow high
resolution to be attained even for long fiber leads and
lossy connections.

Multiple sensors can be connected in series in each opti
cal fiber, in combination with one, four or eight optical
channels with parallel acquisition. The FS22 - Industrial
BraggMETER SI is particularly suitable for large scale
sensing networks acquiring a large number of sensors
simultaneously and providing 1 S/s acquisition rates with
sub picometer resolution.

The BraggMETER is available either in Standard and
Rack-mountable formats. This Manual applies to the fol
lowing equipment:

Regulatory and Certification Considerations

2.2 Laser Safety

The FS22 - Industrial BraggMETER SI contains a laser in
its core. A laser is a light source that can be dangerous
to people exposed to it. Even low power lasers can be
hazardous to a person's eyesight. The coherence and
low divergence of laser light means that it can be focused
by the eye into an extremely small spot on the retina,
resulting in localized burning and permanent damage.

The lasers are classified by wavelength and maximum
output power into the several safety classes: Class 1,
Class 1 M, Class 2, Class 2 M, Class 3R and Class 4.

2.2.1 Symbols

Warning symbol Class 1 Laser symbol

2.2.2 Class 1 Laser

The FS22 - Industrial BraggMETER SI is a class 1 laser
product:

«Any laser or laser system containing a laser that cannot
emit laser radiation at levels that are known to cause eye
or skin injury during normal operation. »

12 A4249-8.0 HBM: public FS22 SI

Regulatory and Certification Considerations

It is safe under all conditions of normal use. No safety
requirements are needed to use Class 1 laser devices.
This product contains a laser within an enclosure that
prevents exposure to the radiation and that cannot be
opened without shutting down the laser.

2.2.3 General Precautions Considerations

Everyone who uses a laser equipment should be aware
of the risks.

The laser radiation is not visible to the human eye but it
can seriously damage user's eyesight.

The laser is enabled when the interrogator is turned on.

Users should never put their eyes at the level of the hori
zontal plane of the optical adapters of the interrogator or
uncovered optical connectors.

Adequate eye protection should always be required if
there is a significant risk for eye injury.

When an optical channel is not in use (no optical connec
tor plugged to the interrogator), a proper connector cap
must be used. The optical connectors are subjected to
maintenance and/or inspection. Please refer to

section 4.4.1 “Dirty Connector“ for maintenance
procedure.

Do not attempt to open or repair a malfunctioning inter
rogator. It must be returned to HBM FiberSensing for
repair and calibration.

tor connect the power cable to the interrogator Power
Connector (number 3 on Fig. 3.1 or number 4 on
Fig. 3.2). To acknowledge proper power supply, the
POWER LED will turn green during 2 seconds after con
necting the power supply.

3.2.2 Optical Connectors

The FS22 - Industrial BraggMETER SI can be purchased
either with FC/APC, or SC/APC optical connectors. num
ber 1 on Fig. 3.1 exemplifies FC/APC connectors.

Attention should be paid to the cleaning of the optical
connectors. A dirty connector can compromise the mea
surement and will degrade the interrogator performance.
It is advisable to frequently clean the connectors using
appropriate tools.

FS22 - Industrial BraggMETER SI can have one, four or
eight optical channels in parallel.

3.2.3 Ethernet Connection

Connect the Ethernet RJ45 connector directly to a PC
using a Ethernet cross-over cable, or to a network con
nector using a direct Ethernet cable (in this case, the

3.3 Switching On

Pressing the ON/OFF button will start the interrogator.
The STATUS LED will start blinking at 2 Hz. After
approximately 30 seconds it will start blinking at 1 Hz.
This means that the interrogator is already on and
responsive, but the optoelectronic module is still warming
up. After approximately 90 seconds it should stay on per
manently. This means that the interrogator is able to
measure.

Single interrogator

Operation

3.5.3 Synchronization

In order to achieve synchronous measurements between
different devices the NTP (Network Time Protocol) syn
chronization via Ethernet must be used.

Each optical Interrogator can synchronize its internal
clock with an NTP server. It is possible to achieve accu
racies of 1ms or higher, depending on whether or not a
dedicated NTP server is being used.

Further information about NTP can be found at

http://www.ntp.org

.

Measuring Systems Typology

A measurement system can be as simple as a single
interrogator or a bit more complex with combined inter
rogators with the same or different sampling rates, and
interrogators combined with other equipment.

For the usage of a single interrogator no special synchro
nization is needed.

BraggMONITOR SI software can only operate one inter
rogator at a time. If an NTP server is running on the
same PC as the BraggMONITOR SI, the interrogator
internal clock – hence BraggMONITOR SI – will sync.

Multiple
interrogators

If more than one interrogator is used, synchronization
becomes important and if an NTP server is running the
equipment will start synching as soon as a first communi
cation from the server is received.

FS22 SI A4249-8.0 HBM: public 25

Operation

Fig. 3.9

Hybrid

A hybrid measurement system is a system composed by
different equipment types and technologies that can be
operated with different sampling rates. Taking the exam
ple of HBM families a hybrid system could be a combina
tion of Interrogators with QuantumX.

Fig. 3.10

26 A4249-8.0 HBM: public FS22 SI

Operation

Synchronization is again of extreme importance in such
systems. When an NTP server is running the Interrogator
will start synching as soon as a first communication from
the server is received.

For details on the other equipment please refer to their
respective user manuals.

Synchronization process

Each interrogator synchronizes its internal clock with the
NTP server. Upon starting, all devices and the NTP
server need some settling time to achieve the best syn
chronism possible.

The following features for NTP synchronization are avail
able:

Number of devices
to be synchronized

Synchronization
accuracy

Synchronization
settling time

Synchronization
master

Unlimited

10 μs to 10 ms

Up to 30 min during first start, up to 2 min during restart

External SyncMaster, e.g. PC

For a good synchronization, the dedicated NTP server
should run continuously. The accuracy is described by
the two values:

S Offset: average deviation from time server

S Jitter: typical variation range of the offset value

The clock synchronization is classified using the following
offset intervals:

S <500 μs: excellent

S <1 ms: very good

FS22 SI A4249-8.0 HBM: public 27

Operation

S <2 ms: good

S <5 ms: acceptable

S <10ms: poor

S >10ms: not acceptable

A successful NTP Sync is achieved if the offset between
the internal clock of the device and the NTP server is
below 5ms.

The quality of the NTP synchronization can be queried
using the SCPI commands (please refer to section “Syn
chronization” on page 53 for further details).

3.5.4 Operation

The FS22 - Industrial BraggMETER SI interrogator can
be fully controlled using standard SCPI syntax com
mands (for a complete command list, please refer to sec
tion 5.1 “Communication Protocol Syntax” on page 51).

Using the Provided Drivers

These drivers can be used within the LabVIEWTM envi
ronment. To develop custom applications using this
language, copy the drivers' library supplied on the CD.
A set of ready to use examples to run on LabVIEWTM is
also provided.

Important

Before using the provided LabVIEWTM examples on a
PC, make sure the Regional and Language options (in
standards and formats) are defined as dot for decimal
symbol, comma for digit grouping symbol and dash for
date separation.

Operation

Operational States

The FS22 - Industrial BraggMETER SI interrogator has
six operational states:

The error state corresponds to a malfunction of the opto
electronic module of the interrogator. The system can
only recover from this state by resetting.

In the ready state, the FS22 - Industrial BraggMETER SI
is ready to start acquisition.

The free acquisition state enables the FS22 - Industrial
BraggMETER SI interrogator to perform single measure
ments on a specified optical channel. The interrogator
can be configured in terms of threshold and the corre
sponding configuration can be stored for further mea
surements.

The continuous acquisition state allows continuous wave
length acquisition over all optical channels and also per
forms continuous OSA trace acquisition at 1 S/s.

The scheduled acquisition state allows periodic data
acquisition with a pre-defined period and number of sam
ples while saving data to the internal interrogator mem
ory. Whenever the acquisition period minus the number
of samples (at 1 S/s rate) is higher than 10 minutes, the
interrogator will enter into sleep mode during inactive
time intervals, to reduce power consumption. The mini
mum period is 5 s and the number of samples (at 1 S/s)
cannot overcome the defined period.

The FS22 - Industrial BraggMETER SI interrogator starts
on the warming-up state that enables the settling of the
operation parameters and recall of the acquisition con
figuration.
