1.1 General Information
This installation guide applies to the following products:
Part Number Description
K-FS63-50-11-302 FS63 – Embedded Temperature Sensor • Outdoor • FC/APC
K-FS63-50-13-302 FS63 – Embedded Temperature Sensor • Outdoor • SC/APC
K-FS63-50-10-302 FS63 – Embedded Temperature Sensor • Outdoor • NC
1.1.1 Overview
The FS63 - Embedded Temperature Sensors are Fiber
Bragg Grating (FBG) based sensors, designed to be
directly cast into concrete wet mix.
1.1.2 Characteristics
: Robustness
Long-term reliability ensured by innovative sensor
design, careful selection of materials and IP68 packag
ing.
: Completely passive
Inherent immunity to all electromagnetic effects (EMI,
RFI, sparks, etc.) and safe operation in hazardous envi
ronments.
Technical Details
FS63 A4261-3.2 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 Preparing the Structure
The embedded temperature sensor is a sensor prepared
to be embedded in concrete. Its design includes
ruggedized cables that resist such an environment.
Nevertheless, whenever possible, further protection of
cables should be performed on the cables path.
Prepare the sensor cables path with an appropriate, flexi
ble and resistant tube.

Depending on the control on the construction site, HBM
FiberSensing suggests two different solutions regarding
the access to the sensor connections:
If the stripping of the concrete can be closely controlled,
the protection tube can pass directly through a hole in the
formwork (Fig. 2.3 and Fig. 2.4). Later, when the form
work is removed, a box can be placed over the exit of the
Sensor Installation

cables so that connections can be conveniently pro
tected.

Fig. 2.4
If the stripping cannot be controlled, it is advisable to use
embedded protection boxes. Fix the box to the formwork
with screws that can be later on removed before the
stripping.
