We would be pleased to welcome you on booth 4 / Salzburg – May 11-13

Discover or re-discover the benefits that our high-speed sensors can bring to the design and validation of your high technology products.

We look forward to discussing your current and future developments in the field of rotating machinery and to providing you with our expertise in fibre optic tachometers.

It will be the occasion to show our new products

You will see in particular the new amplifier which benefits from the know-how of the design office of TEXYS GROUP, company of which OPTEL-TEXYS is a subsidiary since 2020.
The electronics combine the performance of the analogue circuit with the intelligence of a microprocessor. Thus, the detection adjustment parameters are managed automatically and do not require a potentiometer.
This has led to the reduction of size and weight and gives the advantage to be more easily embedded.

To prepare your meeting with us, we invite you to contact Mr Ivan TATTIER

From the 06 to the 09 of September 2021, Texys Group is looking forward to your personal visit at the "Measurement World" in Lyon (France).

This year, additional to the products of our sisters companies “Optel-Texys” and "LGS by Texys", we will also exhibit the original Texense sensors.

Looking for a solution to analyse your rotating machine? Our fibre optic sensor systems are the reference in the domain.

Why choose to use OPTEL-TEXYS optical tachometers?
-    For their wide bandwidth and low response time which allow you to "see" very fast, very high frequency phenomena.
-    Because transmission and reception are separate and are not timed by an internal clock: you will not lose any information due to a reception stop time when transmission is active.
For their low phase shift and stability of TTL signals transmitted to the acquisition system even under conditions of strong angular vibrations.
-    For their ability to combine very high resolution and easy integration in confined environments
-    By the very nature of the fibre optic probes which provides immunity to electromagnetic waves and allows them to be used in ATEX zones
-    Detection in liquids or oil mist.

For which applications is it necessary to use the most powerful sensors on the market?
-    Acyclism detection and performance improvement
-    Torsional Vibration measurement for diagnosis and research of curative and preventive solutions
-    Tip Timing Analysis on Turbomachinery Blades
-    Non-contact Dynamic Torque Measurement
-    Balancing on Turbocharger and very high-speed rotating systems
-    Bearing analysis by ball detection in through-beam mode.
And more...

Do not hesitate to contact us, our technical and commercial team is available to answer your questions.

The fibre optic sensors manufactured by OPTEL-TEXYS fit perfectly within the framework of the activities of ASTE (Association for the development of Environmental Sciences and Techniques) as they meet the needs of engineers and technicians involved in environmental testing:
- Vibration for detection of torsion and bending
- Climatic thanks to the temperature resistance of the probes
- EMC through the natural immunity of optical fibres to electromagnetic fields.
With new "Very High Temperature" optical probes associated with the sensors of the 152 series, OPTEL-TEXYS opens up the field of possibilities in a temperature range above 200°C.
For example, speed measurement on turbochargers for balancing or acoustic and vibration analysis may concern the "Hot" side of the system. Similarly, blade deformation (or Tip-Timing) measurements on turbines will be feasible in an environment that can reach temperatures of around 600°C.
Another advantage in the use of fibre-optic sensors is that they can detect rotating parts in confined areas or spaces that are difficult for a conventional sensor to access, which is often the case for the applications mentioned.
An example of turbocharger detection is available on the OPTEL-TEXYS Youtube channel. If you have any questions about our solutions, please send an email to contact@optel-texys.com.

In the continuity of the presentation made during the "Rdv de 9h30" organized by the Réseau Mesure, OPTEL-TEXYS offers you an introductory video on non-contact torque measurement.

If you are interested in this subject or, in general, if the analysis of rotating machines based on speed measurement is part of your scope of activity, do not hesitate to visit our website or to contact us at contact@optel-texys.com.

A technician, or test engineer, often wants to avoid introducing an additional mechanical component when performing torque measurement on a rotating machine.

Either because he will have to integrate a torquemeter on the shaft line, or because he will embark on the shaft itself a measuring element coupled with telemetry and thus risk inducing an unbalance.

The current market offers solutions but these find their limits when the machine starts to reach high speeds or when there is not enough space to install an additional element on the shaft.

OPTEL-TEXYS answers these problems thanks to its non-invasive fibre optic sensors. Our solution, combined with partner software, allows us to push the current limits very far.

We invite you to discover it during the 9:30 am meeting, presentation session organized by the Réseau Mesure on February 26th.

The upcoming intensification of the electrification of motor vehicles will have a strong impact on the development of motors and their components. The variety of technologies will require better characterization of torque and power. OPTEL TEXYS is already addressing this issue with its high-speed optical sensors.
The example of a French company, which selected 152M sensors for the characterization of a 52 KW motor, shows that it is quite possible to measure torque and speed contactless and without additional inertia up to very high speeds (> 50,000 rpm), which are inaccessible for conventional torque meters.
The picture shows our optical sensors detecting engravings at the ends of a shaft positioned between the motor and the brake. Processing the signal from the variation in angular position measured with accuracies of the order of 10-3 degrees allows us to calculate the dynamic torque with results accurate to 0.02%.
Thus, OPTEL TEXYS pushes the limits of torque measurement at very high speeds with performance equivalent or better than existing products while adding the convenience of non-contact.

A new technology has recently been added to the landscape of bolted joint characterisation, by the Nevers, France-based company, TEXYS Group.
The company has developed the patented TM-FAST instrumented bolt technology which combines the traditional use of strain gauges with an innovative installation in the bolt head.
The proven advantages are the measurement of clamp load in bolted joints while preserving the mechanical strength of the bolts.
In addition, the measurement is accessible via wireless interrogation with NFC technology for quick checks of the tightening tension and also when the screws are wired to data acquisition systems for dynamic analysis.
Thus, TM-FAST screws are intended for uses as varied as predictive maintenance of sensitive assemblies, the design of complex systems where force measurement complements mechanical calculations, and product validation by analysing behaviour in the bolted joint.

OPTEL TEXYS fibre optic sensors for the analysis of turbomachinery. The method called Tip Timing is used for the non-contact measurement and characterization of rotor blade vibrations in land or aircraft turbomachines. These blade vibrations are a major cause of failure. It is essential to have a powerful means of measuring these vibrations that is non-intrusive, reliable and simple to use.
This is why it is common to use non-contact sensors, especially optical sensors, to detect the passage of a blade very accurately and quickly. OPTEL TEXYS develops fibre optic sensors whose performance has made them the reference in the field of rotating machine analysis. Our customers using the Tip Timing method have chosen the 152M sensor with double TTL and Analog output.
Its large bandwidth makes it capable of receiving more than a million information per second and its detection speed allows to read blade passage times of a few tens of nanoseconds. The direct benefit is the reduction of uncertainties compared to other non-contact means of approaching strain gauge methods while remaining non-intrusive. Another advantage lies in the analogue output which provides a raw signal whose content rich in vibration information can be complemented by an in-depth analysis of the phenomena.

OPTEL THEVON and TEXYS INTERNATIONAL, two companies specialised in the design and manufacture of high technical added value sensors, considered that their shared values and complementary activities fully justified a merger and would enable them to offer their customers a wide range of products, "quite exceptional", according to Pierre-Jean THEVON, director of OPTEL THEVON and Philippe LEUWERS, manager of TEXYS INTERNATIONAL.
