Strain gauge - 0.03 - 0.1 µm | Q-100

Increases safety : Finds "hot spots" and stress concentrations

Enabling technology : Measurement on contours and any material

Saves costs : Fewer failures and shorter occupation of test benches

The Strain Sensor Q-100 is a unique device for rapid strain measurement on any component with very little preparation.
The Q-100 sensor head is simply positioned on the surface of the area to be inspected and it automatically analyzes the geometry and deformation of the inspected area when a load is applied to the component.
From these data the complete strain field is derived within seconds.

Fiber optic strain gauge - max. 10 000 µe | FOS-N

The FOP-MA is a fi ber optic pressure sensor designed for use in acoustics or
microphone applications or whenever a very sensitive pressure sensor is
needed. It features high frequency response and a high sensitivity to detect
slight pressure variations under the most adverse conditions.
The FOP-MA acoustic pressure sensor offers small size, high accuracy, immunity to
EMI/RFI, and resistance to corrosive environments.
Research engineers in the acoustics fi eld may now measure acoustic phenomena
on transportation vehicles and other structures. Low profi le, high-sensitivity sensors
are ideal for applications such as automotive and aerospace wind tunnel
testing, aerodynamic testing and analysis, aircraft cabin and cockpit noise testing,
and acoustic fatigue testing on airframes. They may also improve process and
product technology by monitoring the performance of specifi c properties over
time to provide accurate information on changes in pressure during the operation,
the manufacturing process or throughout the lifetime of a product. The use of
the FOP-MA acoustic pressure sensor allows a complete pressure ana lysis in the
most challenging environments.

Fiber optic strain gauge - 2000 - 4000 µe | SFO-W

The SFO-W is a fi ber optic, spot-welded strain sensor designed for civil
engineering applications such as the monitoring of dams, bridges, tunnels,
and other structures.
The SFO-W strain sensor offers small size, high accuracy, immunity to EMI/RFI, and resistance to corrosive environments with a high temperature range.
Manufacturers, civil structure designers, and research engineers may now improve structure technology by monitoring the performance of civil structures. Monitoring specifi c properties over time will help improve the safety and durability of these structures. The deployment of SFO-W strain sensors within a structure, provides accurate information on changes in strains in structural members of buildings, bridges, tunnel linings and supports during and after construction. The use of the SFO-W strain sensor allows a complete stress/strain analysis in the most
challenging environments.
The SFO-W consists of a small diam eter stainless steel tube welded on a steel sheet, suitable for spot-welding on steel surfaces.
The sensor is based on a unique fi ber optic strain sensor which constitutes a breakthrough in fi ber optic sensing. The extrinsic Fabry-Perot strain sensor is bonded inside the steel tube, thereby following the tensile or compressive movements of the spot-welded sensor.

Fiber optic strain gauge - 2000 - 6000 microstrain | EFO

The EFO is a fi ber optic strain sensor especially designed to be embedded
in concrete, ideal for composite material engineering research and civilengineering applications such as monitoring stresses in structural members of buildings, bridges, tunnel linings and supports during and after
construction.
Smart structures are now possible thanks to FISO’s EFO fi ber optic strain sensor.
The deployment of sensors within the structure, whether it is a bridge or a dam, provides accurate information on changes in load and strains in reinforced concrete and mass concrete. Measuring strain in tunnel linings and supports is also possible with the EFO fi ber optic strain sensor.
The EFO is a 70 mm long sensor designed to be embedded in concrete. The sensor is based on a unique fi ber optic strain sensor which constitutes a breakthrough in fi ber optic sensing. It consists of a stainless steel body, with two fl anges for better adherence to concrete. The intrinsic Fabry-Perot strain sensor is bonded in a very small diameter longitudinal hole located in the center of the steel body. Intrinsically safe, it is immune to EMI, RFI, and lightning. It allows static/dynamic measurement and can deliver signal transmitted over long distances with no interference due to fi ber bending.
