Equipment for material testing
Sensima Inspection is a high tech company founded in 2009 as a spin off of the Swiss Federal Institute of Technology.
Sensima Inspection develops and markets advanced electro-magnetic solutions for non destructive testing (NDT) and quality control, with a focus on crack detection, sizing, and monitoring in metallic components. We offer a unique combination of the most advanced technologies including IC design and a recognized expertise in non destructive testing.
Our innovative products are designed to improve performance, to reduce equipment size and weight, and to facilitate integration in and interfacing with your inspection systems.
While drone based non contact inspection (optical, 3D stereoscopy, IR, lidar,...) is moving quickly to a commodity business, huge efforts are still to be made in the aerial robotics and NDT measurement technology to access contact NDT (i.e. Ultrasound, Eddy Current). Significant steps into that direction are made in the frame of the AEROARMS collaboration supported by the H2020 programme as demonstrated in the video above (in french).
Sensima Inspection teams up with the major organisations in Europe developping advanced aerial robotics in the frame of the H2020 project AEROARMS.
The objective of the project is to develop breakthrough industrial inspection solutions integrating the most recent robotics technologies.
In the most challenging deliverables of the project,
the consortium will deliver industrial aerial robots able to perform contact NDT (EC, UT) leveraging the miniaturised, wireless inspection technologies of Sensima Inspection.
Together with its partners inspire AG/ETHZ and HESSO-HEPIA, Sensima inspection has been awarded a prestigious grant by the Swiss Space Center, the
organisation in charge of the Space activities for the Swiss Government. In the frame of the project entitled "Part integrity monitoring during Selective laser
melting", the partners will develop innovative process enabling the inline generation of quality documentation during the metal additive manufacturing (AM).
The results of this project will be a key component of future AM machines able to produce component with quality standard required for space applications.
The success of Sensima underwater NDT tools has raised the attention of asset owners
willing to perform the underwater inspection of various infrastructures. On December 5, 2016, a new UW grid inspection scanner called
UW Grid Explorer, has been commissioned for the periodic inspection of the hydropower dam of Verbois in Geneva. This inspection tool enables
the underwater inspection of 14 bars simultaneously at a scanning speed of 0.5m/s. The above picture shows the rack of 14 U-shaped probes and the
connection box. The system is powered by the multichannel eddy current unit of Sensima, with the real time display of the signal of 14 Eddy Current channels.
Sensima Inspection will present its latest products at the ASNT conference, the largest event for technicians, researchers, and professionals working in the
non destructive testing industry. In addition to its Ultra-Portable Eddy Current (UPEC) line of flaw detectors, Sensima Inspection is proud to present its
underwater flaw detectors with new features allowing ROV integration.
Sensima Inspection has been invited by EPFL to the Salon des Technologies et de l'Innovation de Lausanne at the Swiss Convention Center.

Sensima Inspection is pleased to announce the foundation of SEDECT SA, the latest chapter in the story of SENSIMA that started in 2008.
SEDECT SA will pursue the development and the commercialisation of innovative metal detectors for security applications.
The initial project is conducted in collaboration with Geneva Airport and will lead shortly to the delivery of
detection devices to this airport. In the following video, the product and its impact on the passenger control
is presented by Geneva Airport.
Sensima Inspection has been invited by Institut de Soudure to present its latest crack monitoring solutions.
About 120 experts of the maintenance of pipeplines have participated to this technical meeting.
The application of the eddy current monitoring solution for Oil & Gas has been presented by Sensima Inspection and discussed with the participants.
For the 5th time, Sensima Inspection will present its latest products at the ASNT conference, the largest event for technicians, researchers, and professionals working in the
non destructive testing industry. This year, the Ultra-Portable Eddy Current (UPEC) line of flaw detectors, introduced in 2013, is extended to multi-channel instruments.
The full line of testers retains its uniqueness in terms of compactness, performance and ease of interfacing with digital mobile devices.
Together with its partner Hydro Exploitation, Sensima Inspection has been invited to the Technical Days of the Institut de Soudure, Paris, France to present its latest
developments in condition based monitoring. A particular attention was given to automated system operating in underwater environement and to the delivery of the information
allowing the asset owner to make decision without complex further information processing.
It is widely known that eddy current measurements can provide useful information on the properties of ferrous materials.
Modifications of the microstructure and of the dislocations distribution caused by heat treatment or work hardening result in variations of the magnetic domain wall motion, which affect the electromagnetic response of the sample.
While the underlying microscopic mechanism relating these quantities is difficult to describe quantitatively, the relation between the electromagnetic response and the microstructure
is a very efficient empirical tool to sort parts, both by comparaison with reference batches or by statistical analysis of samples.
Responding to requests from both private companies and governmental agencies, Sensima Inspection initated 2 years ago the development of a novel crack monitoring sensor for civil engineering and oil and gas applications. The prime target of this sensor is the monitoring of the most important parameters of a crack detected on a metallic part, such as crack tip position, crack depth, and load response. This technology will ensure that a dramatic evolution of the crack occuring before corrective action is completed does not remain unnoticed. Key to the development of the sensor was the capability to produce a miniaturised, multichannel, fully integrated, reliable and cost effective EC system matching the growing demand of the field for "the right sensor at the right place for the right reason".
The sensor performance validation phase has been successfully completed in the Steel Structures Laboratory of Prof. Alain Nussbaumer at EPFL opening the route for
the first on site pilot project to take place later in Switzerland this year.
At the occasion of the ASNT SMT conference, Sensima Inspection will present its latest developments for the monitoring of cracks in metallic
This inspection system is aimed at detecting cracks on a grid protecting the turbines intake of a run-of-river power plant. The scanner, which contains 8 U-shaped eddy current probes and the control electronics, is attached to the bucket of the crane that automatically cleans the grid from various materials that may obstruct the intake. A cumulated bar length of 160m is inspected in 1 minute as seen in the above movie. The full grid, corresponding to a total 4.5 km of bars, can therefore be inspected in one day.
"It is impressive how this advanced technology could be integrated in an existing cleaning crane. We can therefore run this inspection device with zero interference with the plant operation." said the technical manager of the power plant.
The scanner has been jointly developed by Sensima Inspection and Hydro Exploitation for the power plant owner (SIG-Geneva).
The Region of Nyon is a dynamic, rapidly growing region located midway between Geneva and Lausanne. 4 years ago, Sensima Inspection decided to relocate its headquarter there to benefit from this outstanding environment and the proximity of high quality suppliers. Today, Sensima Inspection has been awarded the first Innovation Award by the REGIONYON Council for the innovative accomplishments of our company and its potential for growth. The press release is available here.
At the occasion of the ASNT tradeshow, Sensima has released the UPEC, its latest eddy current tester. With a software running both under Windows and Android, UPEC is the first eddy current instrument designed for the mobile technologies.
Mobile and portable devices are now ubiquitous. Why should an NDT equipment manufacturer impose one to you ?
Last month, Sensima team performed the first on-site tests of a new system aimed at mapping penstocks for wall thinning (corrosion) and flaw detection. This project
is conducted jointly with
Alstom Inspection Robotics and
Hydro Exploitation with the support of The Ark Foundation.
This unique technology consists of an ROV with advanced navigation capability that is instrumented with ultrasonics and eddy current NDT equipment.
The final NDT product, that will be released in September 2013, will enable large scale, cost effective mapping of the penstocks used for example
in hydropower plants. The automated reporting functionality will help asset owners make important decisions on maintenance and operation.
The Sensima Underwater Eddy Current Tester is released. The compactness and performance of this product allow underwater NDT in optimal
conditions. Available in absolute and differential configurations up to 100 bars. Accessories, integration, and customization on request.
The Sensima Ultraportable Tester has been integrated on a Buggy together with an eddy current sensor. The system can
be used to performed various remotely controlled EC inspection tasks. Developed in collaboration with
Alstom Inspection Robotics.
Hydro Exploitation has recently performed an extensive inspection of the underwater grids protecting the intake of a hydro power turbine.
Key to this inspection was the Underwater Eddy Current Equipment of Sensima Inspection which was used for the first time in real conditions.
