Capteur de distance à résolution élevée - High resolution distance sensor

Bonjour,
Je souhaiterai mesurer une faible distance variable (<10cm) mais à la résolution du 1/10 éme de mm
Quel capteur puis-je utiliser ?
Bonne journée
Cordialement

Hello,
I would like to measure a small variable distance (<10cm) but at the resolution of 1/10 th of mm
Which sensor can I use?
Have a good day

Bonjour et merci pour cette réponse rapide... mais le coût des capteurs est vraiment très élevé...
Hello and thank you for this quick response ... but the cost of the sensors is really very high ... :frowning:

Looking at your numbers and your expected resolution the cost will be high. You want a range of 100 mm with a 0.1 mm resolution and I assume at least a 0.1 mm uncertainty (accuracy). In the past for a few precise distance measurements I used several Micro-Episolon products.

They are far from inexpensive and I suggest you speak with an applications engineer.

ok
As it is for a single and personal use, I would like a reasonable cost …
The displacement to be measured being less than the maximum offered (1 inch), I think this model can be satisfactory … provided that it is properly interfaced with the ARDUINO card

Comme c’est pour un usage unique et personnel, je souhaiterai un coût raisonnable…
Le déplacement à mesurer étant inférieur au maxi proposé (1 pouce), je pense que ce modèle peut donner satisfaction… à condition de l’interfacer correctement avec la carte ARDUINO

And I think the answer regarding the interface is there ... :slight_smile:
Et je pense que la réponse concernant l'interface est là...
