Piranometru spectral

Caracteristici generale

- Piranometru spectral plat conform ISO 9060:2018 măsoară iradierea pe o suprafață plană (W/m²)
- Mic, ușor și compact special conceput pentru monitorizarea PV la scară mică și controlul obișnuit al eficienței sistemelor PV
- Folosește un senzor termopil care oferă măsurători precise, fiabile și optime conform standardului de referință
- Disponibil în 2 versiuni pentru a îndeplini cerințele de instalare:
• LPPYRA-Lite pasiv
• LPPYRA-LiteAC activ cu 2 fire (bucla de curent) ieșire 4…20 mA.
- Ușor de configurat și instalat: soluția perfectă pentru instalarea directă înclinată.
- În cazul poziționării orizontale, este disponibilă și o bază de fixare opțională care integrează un dispozitiv de nivelare.
