PRISMA INSTRUMENTS & GAUGE BOURDON

Les pressostats intelligents PI800 de Prisma Instruments disposent de capteurs de haute précision qui affichent la pression en temps réel. Ils sont équipés d'un écran LCD de grandes tailles et disposent de diverses fonctionnalités, telles que la mise à zéro, le rétro-éclairage, le bouton ON/OF, d’unités de mesures sélectionnables, protection par mot de passe, d’un contact d’alarme réglable sur toute l’échelle. Ils sont simples à installer et à utiliser. Leurs coquilles ainsi que leurs connecteurs sont en inox 304. Ils peuvent être utilisés pour mesurer les gaz, les liquides, les huiles et d’autres fluides adaptés à l'acier inoxydable. Le régulateur de pression numérique PI800 est conçu pour contrôler la pression d'huile, la pression d'air, la pression d'eau (ou toute autre media) pour démarrer ou arrêter une pompe ou un compresseur une valeur de consigne donnée. Avec la fonction de protection par mot de passe, de détection de tension intelligent, de protection contre les sous-tensions et de réglage de la vitesse de réaction, le pressostat PI800 est l’outil idéal pour contrôler avec précision une pression et protéger plus intelligemment vos équipements. Doté d’un menu ergonomie il pourra aisément remplacer vos pressostats mécaniques; vos transmetteurs de pression + instruments secondaires etc. Cette série utilise l'acquisition et le traitement de données MCU à haute vitesse. Il vous permet d’automatiser la surveillance d’une chaîne de production, d’équipements sous pression ou la surveillance de d'environnement ou d'autres applications.
