EJX110B Transmetteur de Pression Différentielle Sans Fil

Le transmetteur de pression différentielle sans fil haute performance EJX110B comprend un capteur résonateur en silicium monocristallin il convient à la mesure du débit de liquide, de gaz ou de vapeur ainsi que du niveau, de la densité et de la pression du liquide. Ces appareils transmettent non seulement les variables de processus, mais également les paramètres de réglage à l'aide d'un signal sans fil. Les transmetteurs fonctionnent avec des piles internes et le coût d’installation peut être réduit car le câblage n’est pas nécessaire. La communication est conforme aux spécifications du protocole ISA100.11a.

Details

  • Conception de piles longue durée
    La conception à très faible consommation de courant utilisant deux piles lithium-chlorure de thionyle à haute capacité assure un fonctionnement sans fil pendant des années.
  • Rejoindre un réseau sans fil sécurisé
    Communication infrarouge entre les appareils pour la configuration et le paramétrage du réseau sans fil.
  • Temps de mise à jour rapide
    Sélectionnable de 0,5 seconde à 60 minutes pour que la valeur de processus mesurée soit émise sans câblage.

Vue générale:

Geothermal power plants create electricity from geothermal energy. These power plants are similar to other steam turbine station; however their heat source is that of the earth's core. The created steam is used to turn the turbine for the production of electricity. Technologies include Dry steam, Flash steam and Binary cycle power stations with Binary cycle being the most common geothermal plant in current production. In the process of geothermal power generation the facility needs to monitor various processes, as in this case steam line pressure sits in remote from control room's location.

Notes Applicatives
Industries:
Vue générale:

The client wanted to monitor the injection gas pressure of gas lift remotely in central control room. Antitheft measures are needed to install new equipments and cables.

Vue générale:

Both bulk and finished inventories are stored in distributed tank farm remote from the site operations. These are difficult to instrument due to the infrastructure cost involved. These are then monitored daily by patrol rounds. While effective, this method does require a large skilled labor force to monitor all of tanks. This can impose an additional risk when the stored medium is of a hazardous nature.

Vue générale:

The use of wireless technology in industrial automation systems offers a number of potential benefits, from the obvious cost reduction brought about by the elimination of wiring to the availability of better plant information, improved productivity and better asset management. However, its practical implementation faces a number of challenges: not least the present lack of a universally agreed standard. This article looks at some of these challenges and presents the approach being taken by Yokogawa.

Vue générale:

In recent years, more field wireless devices have been used in hazardous areas. Meanwhile, in plants that are usually recognized as hazardous areas, there are numerous metallic tanks and pipes that easily shield or reflect radio waves, as discussed later, thus resulting in a poor environment for wireless communication.

Vue générale:

The innovation of wireless technology increases the use of wireless communication in the industry. The introduction of wireless communication to plants, however, requires strict features such as robustness, real-time responsiveness, and low power consumption. This has restricted the use of wireless communication to limited applications such as data logging and device status monitoring that does not require strict real-time responsiveness and data arrival reliability in communication.
