T7I SMART Submersible level transmitter-1

TRASMETTITORE ELETTRONICO Dl LIVELLO A SOMMERSIONE SMART ELECTRONIC SUBMERSIBLE LEVEL TRANSMITTER SMART Sistema Gestione Qualita, Ambiente e Sicurezza - Quality Management System, Environment andSafety La serie T7I comprende trasmettitori elettronici di pressione SMART con uscita 4-^20 mA e con protocollo di comunicazione digitale HART®. I sensori vengono calibrati singolarmente ed unitamente al proprio separatore. La configurazione e le regolazioni possono essere eseguite localmente, per mezzo di pulsanti e display, od a distanza mediante comunicatori compatibili con il protocollo di comunicazione HART®. T7I series includes SMART electronic transmitters with 4+20 mA output and HART9 digital communication protocol. Sensors are calibrated individually together with their own seal. Configurations and adjustments can be made locally, by means of push buttons and display, or remotely using HART9 communication protocol. CARATTERISTICHE TECNICHE - Uscita 4-^20 mA tecnica 2 fili (max 21,5 mA) lineare o quadratica (V) + Protocollo di comunicazione HART® - Velocita di risposta: <256ms (Std. Hart®) - Frequenza di aggiornamento della variabile misurata: Solo con uscita Hart®: -500 ms (su richiesta specifica) Solo con uscita Hart®: -500 ms (su richiesta specifica) - Carico massimo: Rlmax = (Vcc - 12V) / 21,5 mA con uscita - Stabilita a lungo termine < 0,15% FS per anno (*) Note (*): L'accuratezza e le derive sono riferite a strumenti con sensore e membrana integrali; possono variare in funzione del tipo di sensore utilizzato e dal diametro, spessore e materiale della membrana.
