Anemometro NRG S1

SARTELCO SISTEMI
SARTELCO SISTEMI

L’equilibrio unico tra alta precisione e basso costo rende l’anemometro S1 ideale per ridurre l'incertezza del dato nelle campagne anemometriche nonché nei test delle prestazioni di potenza. Un comprovato sistema di cuscinetti e un robusto design in metallo garantiscono il funzionamento del sensore per molti anni anche in condizioni climatiche avverse.

ROBUSTEZZA

NRG ha testato sul campo per oltre un anno in svariate siti con situazioni climatiche differenti, più di 60 anemometri NRG S1. Inoltre DNV GL ha eseguito una verifica indipendente dai test della stessa NRG.

I test di sovratensione che NRG ha condotto sui sensori hanno dimostrato che l’anemometro S1 ha una resistenza alle sovratensioni di corrente elettrica  superiore agli altri anemometri di Classe 1 testati (comunemente usati nel settore dell'energia eolica), riportando danni di minor entità.

L'anemometro NRG S1 è stato inoltre ampiamente testato per ricevere la conformità IEC e CE, oltre che il grado di protezione IP55, il più alto standard IP raggiungibile per gli anemometri a tazza.

CLASSIFICAZIONE

L'anemometro NRG S1 è l'unico anemometro classificato secondo le due edizioni della norma IEC 61400-12-1, e ciò consente un confronto sia con i nuovi anemometri che con quelli più datati.
