OPTEL-TEXYS 152 series : a reliable, high-performance optical tachometer

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...

OPTEL-TEXYS - ASTE

OPTEL-TEXYS - ASTE

OPTEL-TEXYS - ASTE

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.

INTRODUCTORY VIDEO ON TORQUE MEASUREMENT

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.

PRESENTATION SESSION BY THE RESEAU MESURE ON FEBRUARY 26th

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.

Couple Sensor

Couple Sensor

L’intensification prochaine de l’électrification des véhicules automobiles va fortement impacter le développement des moteurs et de leurs composants. La variété des technologies nécessitera une meilleure caractérisation du couple et de la puissance. OPTEL TEXYS y répond déjà grâce à ses capteurs optiques hautes vitesses.
L’exemple d’une société française, qui a sélectionné les capteurs 152M pour la caractérisation d’un moteur de 52 KW, montre qu’il est tout à fait possible de mesurer le couple et la vitesse sans contact et sans inertie additionnelle jusqu’à des vitesses très élevées (> 50000 rpm), inaccessibles pour les couplemètres classiques.
L’image montre nos capteurs optiques détectant des gravures aux extrémités d’un arbre positionné entre le moteur et le frein. Le traitement du signal issu de la variation de la position angulaire mesurée avec des précisions de l’ordre de 10-3 degré permet de calculer le couple dynamique avec des résultats précis à 0,02%.
Ainsi, OPTEL TEXYS permet de repousser les limites de la mesure du couple à très hautes vitesses avec des performances équivalentes voire meilleures que les produits existants tout en ajoutant la praticité du sans contact.

TM-FAST

TM-FAST

Depuis peu, une nouvelle technologie vient s’insérer dans le paysage déjà bien occupé de la caractérisation des assemblages vissés, c’est celle proposée par TEXYS GROUP, société française située à Nevers. Celle-ci a mis au point la technologie brevetée de boulons instrumentés TM-FAST qui associe l’utilisation classique de jauges de contraintes avec une installation innovante dans la tête de vis.
Les avantages avérés sont la mesure des efforts de traction et de flexion tout en préservant la tenue mécanique des boulons. De plus, la mesure est accessible via une interrogation sans fil avec la technologie NFC pour des contrôles rapides de la tension de serrage et également lorsque les vis sont connectées en filaire sur des systèmes d’acquisition à des fins d’analyse dynamique.

Ainsi, les vis TM-FAST sont destinées à des utilisations aussi variées que la maintenance prédictive d’assemblages sensibles, la conception de systèmes complexes où la mesure des efforts complète les calculs mécaniques, la validation de produit par l’analyse du comportement dans la jonction boulonnée. Pour celles et ceux qui souhaiteraient en savoir plus sur cette technologie, n'hésitez pas à nous contacter via le formulaire de Contact.

TIP TIMING

TIP TIMING

TIP TIMING

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 et TEXYS INTERNATIONAL, deux sociétés spécialisées dans la conception et la fabrication de capteurs à forte valeur ajoutée technique, ont considéré que le partage de valeurs ainsi que les complémentarités d’activités justifiaient pleinement une opération de rapprochement et permettraient de proposer à leur clientèle une large gamme de produits, « tout à fait exceptionnelle », selon Jean-Pierre THEVON, dirigeant d’OPTEL THEVON et Philippe LEUWERS, gérant de l’entreprise TEXYS INTERNATIONAL.
