Mesure d'épaisseur du profil dans les installations de calandrage

Mesure d'épaisseur du profil en ligne sans contact dans les installations de calandrage (épaisseur 0,3 mm jusqu'à 18 mm)

Lors de la production de bandes et de panneaux dans les installations de calandrage, la mesure d’épaisseur est un composant important à la régulation et à la surveillance de la production. Les systèmes de la série RTP mesurent l’épaisseur du profil dans les classes de précision, les zones d’épaisseur et les largeurs de différents matériaux.

Avantages :

  • Haute qualité constante des produits et optimisation de l’utilisation des matières premières
  • Régulation rapide lors de l’approche ou du changement de produit grâce à une vitesse de traversée adaptable et à une mesure hautement dynamique
  • Pas de coûts inhérents à l'acquisition d'un système de protection contre les radiations etc. car pas d’isotopes ou de rayons X
  • Stabilité thermique élevée grâce à la calibration in situ
  • Interfaces adaptables aux besoins des clients

Paramètres du matériau :

  • Largeur du matériau : 50 mm jusqu’à 3.800 m
  • Avancée du matériau jusqu'à 25 m/min
  • Température de la surface du matériau max. admissible : 100 °C

 

Les produits de la famille RTP sont des systèmes à cadre en C et en O qui sont dotés d’une technologie de capteur (Thrubeam, triangulation, triangulation à ligne laser) optimale aux applications.

The system RTP 8301.EO operates according to a combination principle consisting of a thru-beam sensor, an eddy current sensor and a measuring roller. The eddy current sensor and the thru-beam sensor are applied on an innovative measuring clamp. Since the sensor measures the distance from the clamp to the roller, the lower side of the material is detected. As the sensor performance is specially aligned with the measuring task a huge measuring gap is possible while offering highest precision. The thru-beam sensor detects the upper side of the material. The thickness of the target is the difference between the two signals. The measuring clamp is equipped with a pneumatically cleaning mechanism and therefore ideal for the application in harsh environment. The profilometer corresponds to the TIP 8301 regarding its functionality. However, it has a different operators´ frontend and evaluation functions.

Special features:

  • Linearity ±5µm
  • Measuring gap 15mm
  • Dimensional thickness measurement, independent from material components

The RTP 8301.CT is based on laser triangulation sensors and therefore ensures the measurement being independently from material constants. The system is designed as O-frame, both sensors detect the thickness according to the differential method. In order to ensure highest precision, the laser beams of the sensors are accurately adjusted during the production process using optoelectronic tools which have been specially developed. The system is ideal for monitoring high-dynamically processes due to its high measuring rate. The O-frame mechanics of the system dispose of a compensation frame which does not vary with temperature and which is used in order to avoid temperature fluctuations of the measuring frame using further sensors. The profilometer corresponds to the TIP 8301.CT regarding its functionality. However, it has a different operators´ frontend and evaluation functions.

Special features:

  • Linearity ±5µm
  • Measuring gap 18mm
  • Dimensional thickness measurement, independent from material components

The RTP 8302.T is based on the laser triangulation sensors and therefore ensures the measurement being independently from material constants. In order to ensure highest precision, the laser beams of the sensors are accurately adjusted during the production process using optoelectronic tools which have been specially developed. The system is ideal for monitoring high-dynamically processes due to its high measuring rate.
