Company Profile

SMARTEC SA was founded in 1996, resulting from the devel-opment of the Fiber Optic SOFO monitoring system at Swiss Federal Institute of Technology, Lausanne (EPFL). In 2000, the company integrated the DiTeSt system (Brillouin) and the DiTemp system (Raman) in its solutions. In 2005, the MuST product line, based on fiber Bragg gratings, was intro-duced. In 2006, SMARTEC joined Roctest, a world leading manufac-turer of instrumentation used in civil engineering, geotechnical and industrial applications. In 2010, Roctest became part of Nova Metrix. Smartec has over 100 years of combined experience in Fiber Optic. You can communicate with SMARTEC in Italian, Eng-lish, French, German, Spanish and Russian. Our experience and expertise are reflected by more than 1000 monitoring pro-jects in 30 countries throughout the world. SMARTEC is committed to provide the best solution with the highest quality products, services, support and competence.

Fiber Optic Sensing SMARTEC product range and expertise cover all major fiber optic sensing technologies. We have been pioneers in the use of optical fiber sensors for Structural Health Monitoring and process control. Optical fiber sensors offer key advantages compared to tradi-tional electrical sensors making them ideal for applications where other sensors are difficult or impossible to deploy: Immunity to electromagnetic interference (EMI), Radio

Frequency interference (RFI) and lightning Non-conducting cables, requiring no grounding or lightning

protection Possibility to use very long cables (up to several kilome-

ters) without repeaters or signal degradation Sensors can be used in explosive environments Sensing elements are made of glass and are not subject to

aging, corrosion or damage from water ingress Ability to combine multiple sensors into a single sensing

line.

Technologies

SMARTEC offers Fiber Optic measurement systems based on the following sensing technologies:

Fabry-Perot Interferometer (FISO brand): These point sensors measure local strain, temperature, pressure and displacement. These quantities are encoded in a change of length of an optical cavity within the sensors that can be measured accurately and with excellent long-term stability. Fabry-Perot sensors are the ideal one-to-one optical replacement of conventional geotechnical sensors.

Low-coherence Interferometers (SOFO brand): These long-gauge sensors measure displacement or average strain over measurement bases that can extend up to several meters. They are ideal transducers for monitoring concrete and geotechnical structures. Deformations are measured by observing the length changes of an optical fiber attached to the structure under observation, compared to a loose reference fiber. This measurement principle allows accurate and stable measurements and insensitivity to temperature variations.

Fiber Bragg Grating (MuST brand): FBG sensors are written in the optical fiber core and act as optical filters, reflecting the wavelength that matches the grating pitch. The reflected wavelength depends on the strain and temperature of the grating, enabling measurement of those two parameters and others that can be transformed to strain (deformation, tilt and acceleration). It is possible to combine multiple gratings with different reflective wavelength on the same fiber (multiplexing).

Distributed Raman Scattering (DiTemp brand): These sensors use an intrinsic property of optical fibers to measure the local average temperature of each meter of fiber for lengths up to several tens of kilometers. This enables the measurement of thousands of temperatures along a single cable. This technology is particularly suitable for detecting and localizing hot or cold spots associated with leaks or other defects.

Distributed Brillouin Scattering (DiTeSt brand): This technology is similar to Raman scattering, but offers the additional ability to measure distributed strain. This enables the detection of local events such as settlements, deformations, cracks and movements.

embedding in concrete and soil as well as sur-

face installation on uneven surfaces or

grooves. For optimal redundancy, the cable

contains two bonded and two free single mode

optical fibers embedded in a polyethylene ther-

moplastic rectangular profile. The bonded fi-

bers measure strain, while the free fibers are

used for temperature compensation (if sensor

deformation <0.2%) or to complete the meas-

urement loop.

This strain sensor is recommended for a wide

range of applications that require distributed

strain sensing, such as soil movement and

ground monitoring. It is suitable for outdoor use

and for direct burial applications, both in

ground and concrete. The DiTeSt HDPE Strain

sensor is a small flexible mini armored fiber

optic strain sensing cable with central metal

tube containing a single optical fiber, metallic

armoring wires and HDPE outer sheath.

SOFTWARE

DiView II & DiView Lite SOFTWARES

The Distributed Data Management and Analysis DiView Software is designed for data storing, processing,

representation and analysis, as well as for the control of single or multiple DiTeSt and DiTemp reading

units. The main functions of DiView software are aimed to measure sensors automatically. The operator can

view in real time the measurements and the alarms on one or multiple maps/graphs. DiView is also able to

trigger alerts for different types of events, including: Strain, Temperature, Leakage and Crack.

SDB SOFTWARE

SDB Software offers a unified tool for measurement and monitoring data acquisition and management. The

SDB software package is designed to manage the acquisition, storage, analysis and visualization of static

data from fiber optic and conventional sensors. It is compatible with all SMARTEC and Roctest data acquisi-

tion units. All data is acquired automatically at pre-defined intervals and stored in a unique relational data-

base. The data can be used to generate alerts based on complex multi-sensor criteria and the software

allows the interface to other external systems such as SCADA.

SOFTWARE

SDB PRO SOFTWARE

SDB View is part of the SDB suite. It enables easy data navigation and visualization of measurements and

an SDB database. SDB View enables a simultaneous display of multiple user-defined views on sensors

chosen from the database over a defined monitoring period. The display can be in form of a map, a table or

a graph plot with associated options such as thresholds plot, colors and sounds on alert criteria. New views

can be generated by the user without any programming and can be exported in different formats for further

analysis or publishing.

SDB VIEW SOFTWARE

The SDB Pro software is part of the SDB software suite. It simplifies data interpretation, visualization and

analysis using real-time calculated virtual sensors called macro-sensors. The value of a macro-sensor is

obtained by applying user-defined mathematical functions to the measurements data from real sensors or

other macro-sensors, and is stored in an SDB database. The definition of macro-sensors is performed using

a user-friendly interface. The representation and properties of this sensor are the same as those of real

sensors, i.e. they can be visualized in tables and diagrams and used in alarm criteria.
