electro-magnetic Solutions for Industrial Inspection


AUTOASSES is a consortium aiming at developping new inspections technologies for the maritime sector. Sensima Inspection will contribute to the project by devlivering miniaturised NDT sensors and electronics matching the payload requirements of inspection drones.

In gas turbines, the presence of cracks in blade firtrees or rotor grooves caused by cyclic loads may lead to the failure of the rotor with major consequences. Sensima Inspection offers to field service companies advanced sensors, matching the geometry of the grooves, to efficiently and reliably inspected them. We also offer very compact eddy current testers to drive the sensor and obtain accurate data, without the pain of cumbersome equipment, dongles, and recurring fees.

We just come back from Middle East where we performed our first field tests with our new TJEX product. Stainless steel OCTG/drill pipe connections have been successfully controlled against cracks with electromagnetic NDT technique. Fully compliant with ISO 15548. Improving inspection quality and traceability, massively saving inspection time, and without using any chemicals. Thanks to our partner SIGS and congratulations to all Sensima engineers for the great development work !

Approaching the end of the AEROARMS H2020 project, and getting closer and closer to commercial applications of contact NDT with drones. See a video here and contact us for more information.

The inspection of the OCTG/drill pipes joints is critical to prevent drill pipe failure, whose costs may reach hundreds of thousands of dollars per day. Whereas the pipe body benefits from automated EMI inspection tools, the techniques used for the inspection of the joints (threads, taper, upset, welds, stress relief section) have still a large margin for improvements. Responding to the demands of the inspection industry, Sensima has developped the TJEX, a rotary Eddy Current scanner. TJEX takes advantage of the advanced technologies of Sensima to improve OCTG inspections in the traceability, reliability, accuracy, documentation, and efficiency. Contact us for more information.

Visit us at the TUEV NORD booth of the HANNOVER MESSE. The contact inspection drone developped by the AEROARMS consortium, to which SENSIMA belongs, will be presented for the first time to the public. This drone offers new perspectives for remotely controlled inspections, introducing contact inspections methods such as Eddy Current and Ultrasound in the drone industry. This drone benefits from the unique inspection technologies and integration engineering of Sensima. .

The business model of Sensima and its spin offs has attracted the attention of INSPIRE, a coordination action funded by the European Commission (Horizon 2020) which seeks to pool knowledge, expertise, and interest around Open Innovation in SMEs with the aim to professionalize Open Innovation (OI) processes in European SMEs.

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.
There is a growing interest for the application of this technique to the quality control (QC) of parts with complex geometries and/or manufactured using exotic techniques such as EDM, SLS, or water jet. Moreover, eddy currents can prove an attractive complementary technology for the detection of subsurface porosity. All these new applications can however not be addressed directly with a standard NDT eddy current instrument.
Sensima Inspection recently released QC systems tailored for these applications, the most challenging beeing the detection of near surface porosity in non ferrous components and the QC of work hardening and heat treatment in minute mechanical parts.
Customers appreciated differentiating features of Sensima Inspection technology and products such as bespoke sensors optimising the contrast between samples of different properties while enabling reproducible measurements of minute mechanical parts. QC system includes an intuitive software that can be parametrised to generate alarms based on calibration sample sets. Compared to alternative technologies, the eddy current QC can achieve impressive throughput rates, a key advantage both for manual tests and automation lines.
In the following printscreen, the response of a set of 300 parts is plotted in the impedance plane representation, the acceptable samples being located in the ellipse, while the red dots correspond to the samples that are rejected.

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 civil infrastructures..

The ASNT SMT conference promotes the exchange of information between national and international researchers, practitioners, and infrastructure owners on the application of Nondestructive Evaluation (NDE) and Nondestructive Testing (NDT) technologies for the condition assessment of highway infrastructure.

Sensima Inspection is happy to celebrate with the underwater NDT community a year of successful utilisation of its UW Eddy Current (UWEC) tester. The most recent project was conducted early this month by the diver company Shape of the World to inspect underwater welds at an offshore location in the Atlantic Ocean. Recent developments to the inspection setup include a full duplex audio connection and simultaneous display of the impedance plane on an UW monitor. This enables both the diver and the inspector located on the surface to view the same information. In particular, the diver can directly monitor the probe response as displayed by the Sensima "UPECView" software.

More details on the UWEC tester in our product page.

All in all, a brilliant demonstration that this Sensima equipment can perform a practical application of the BS 1711:2000 standard for UW NDT!

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 ?
We at Sensima focus on designing the most compact eddy current testers and on developping softwares taking advantage of modern devices. Up to you to decide which portable computer is best suited to your NDT application, large or small display, rugged or not, tablet, laptop or smartphone, Android or Windows.

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.

Our partner 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.

The UW Eddy Current tester is a specialized version of the innovative Ultraportable USB tester developed by Sensima Inspection. The unprecedented compactness and performance of this product match the demanding needs of professional underwater NDT companies.

"The Eddy Current module is very compact, I could safely keep it on my gear all day long, compared to other equipment that have to be attached to a fixed point, this made my life easier for this inspection which covered quite a distance" said the diver after the inspection.
