Capteurs industriels

Temps de cycle plus rapides, meilleur contrôle des processus, temps d'arrêt réduits : une gestion des installations et des machines permettant une utilisation optimale des ressources joue aujourd'hui un rôle essentiel dans la réussite économique d'une entreprise. Les capteurs apportent également une contribution indispensable dans la technique d'automatisation. La vaste gamme de capteurs Festo allie une performance optimale et une fiabilité maximale, garantissant ainsi des processus de fabrication fluides et efficaces.

Mode de fonctionnement des capteurs

Un capteur convertit une grandeur physique à mesurer en une grandeur électrique. De cette manière, les signaux électriques peuvent être facilement transmis et traités. Le capteur peut indiquer si...

  • ...un objet est présent ou non (binaire)
  • ...une valeur de mesure est atteinte (analogique ou numérique)

Types de capteurs

La gamme de capteurs Festo comprend entre autres des capteurs de proximité, des capteurs de pression et de vide, des capteurs de débit, des capteurs optiques et inductifs ainsi que des modèles pour des applications spéciales telles que les acides, les produits alimentaires, les réfrigérants lubrifiants et bien d'autres encore.

Capteurs de proximité

Les capteurs de proximité sont utilisés pour la signalisation binaire de la position du piston des entraînements pneumatiques. Ce sont des capteurs qui détectent le champ magnétique de l'aimant du piston via un capteur de champ magnétique ou un contact Reed. Ils sont montés dans la rainure du vérin sur la position de commutation souhaitée et émettent un signal de commutation normalisé de 24 V lorsqu'ils détectent le champ magnétique du piston.

Sensors for industrial automation: pressure sensors

Pressure and vacuum sensors expand the application range of systems, provide greater process reliability and offer reliable monitoring. They are also easy and quick to use thanks to the standardised control and display concept of the Festo pressure sensors. Pressure and vacuum sensors measure the pressure applied at the pressure input of the sensor. A pressure measuring cell integrated in the sensor compares the excess pressure or low pressure applied to the sensor with the prevailing ambient pressure (relative pressure measuring cell) and outputs it as an electrical signal.

Pick & place machines

Pick & place machines are ready-to-install functional modules for repositioning, feeding and removing small parts in extremely confined spaces. The vacuum sensor uses a configurable threshold to detect whether the workpiece is being gripped securely so it can be moved reliably. The movement is force-guided via a linkage and enables very short cycle times. The assembly machines are designed to be used with electric, servo-pneumatic or pneumatic drives.

Sensors for industrial automation: flow sensors

By monitoring the flow, a simplified diagnostic and condition monitoring process can be implemented: a change in the flow rate is often an indication that problems are likely to occur.

Application areas for Festo flow sensors:

  • Flow and air consumption measurement for energy-efficient sensing
  • Leak monitoring
  • Sensing for picking up very small parts (extra-small vacuum suction nozzles)
  • Checking for presence
  • Leak-tightness inspection

FAQs – frequently asked questions clearly explained

What are sensors?

A sensor is a component that converts a measured physical variable or a chemical effect into an analogue electrical output signal. The physical variable is an input signal that is not electrical, such as pressure, weight, temperature, radiation, magnetic flow, speed or another physical variable.

What types of sensors are there?

There are different types of sensor, such as:

  • Position transmitters
  • Pressure and vacuum sensors
  • Flow sensors
  • Cylinder sensors
  • Inductive proximity switches
  • Opto-electrical sensors

What are sensors from Festo used for?

Festo sensors are used in a wide range of industries and help to increase productivity and process reliability. They enable Festo to offer many industries, such as the automotive industry or food industry, everything from a single source.
