1.1.1 Overview
The FS63 - Weldable Temperature Sensors are Fiber
Bragg Grating (FBG) based sensors, designed to be spot
welded to structures and components.
1.1.2 Characteristics
: Robustness
Long-term reliability ensured by innovative sensor design
and careful selection of materials.
: Completely passive
Inherent immunity to all electromagnetic effects (EMI,
RFI, sparks, etc.) and safe operation in hazardous envi
ronments.

Technical Details
FS63 A4262-3.2 HBM: public 5
: High multiplexing capability
Connection of a large number of sensors to a single opti
cal fiber, reducing network and installation complexity.
: Remote sensing
Large distance between sensors and interrogator (sev
eral kilometers).
: Compatible with most interrogators
Provided with calibration sheet, allowing easy and accu
rate configuration.
: Self-referenced
Based on the measurement of an absolute parameter -
the Bragg wavelength - independent of power fluctua
tions.
1.1.3 Applications
HBM FiberSensing temperature sensors can be used in
several temperature measuring applications. They are
particularly suited for temperature mapping in large struc
tures (SHM).
: Industry
: Civil Engineering
: Energy
: R&D

1.1.4 Quality
All HBM FiberSensing's processes are strictly controlled
from development to production. Each product is sub
jected to high standard performance and endurance
tests, individually calibrated and checked before ship
ping.
HBM FiberSensing, S.A. concentrates all optical sensing
activity of HBM and is an ISO 9001:2008 certified com
pany.
1.1.5 Accessories
The implementation of complex sensing networks in large
structures is made simpler with HBM FiberSensing
accessories. These include cables especially designed to
resist harsh environments as in civil engineering, not only
during construction, but also during the lifetime of the
structure (humidity, corrosion, etc.).
For the installation of weldable temperature sensors in
severe environments, an optional metallic protection
cover is available.

2.2 Spot Welding Machine
HBM FiberSensing uses a machine from Portable
Welders Ltd. Our console is the B3 (http://www.
portablewelders.com/technical-data-poke-consoles.html)
and the Poke Welding Gun is the PG2 (http://www.
portablewelders.com/poke-welding-guns-details.html).
The following instructions are based on our welding
machine and should be considered as an indication,
since ideal settings may differ from situation to situation
(machine, material, thickness, welding ground clamp
position, etc.).
The spot welding machine is composed by a console,
one ground gramp (Fig. 2.1) and one welding gun
(Fig. 2.2).

Typical settings are shown in Fig. 2.3 below. This is a
starting point that should be adjusted to optimize the shot
and the welding.
