Mitar carbon dioxide tare da fitowar PID da VAV Featured Hoto

Takaitaccen Bayani:

Zane don ainihin lokacin auna ambiance carbon dioxide da zazzabi da dangi zafi
NDIR infrared CO2 firikwensin ciki tare da daidaitawar kai na musamman.Yana sa ma'aunin CO2 ya fi daidai kuma mafi aminci.
Har zuwa shekaru 10 na rayuwa na CO2 firikwensin
Samar da fitarwa guda ɗaya ko biyu 0 ~ 10VDC / 4 ~ 20mA na layi don CO2 ko CO2 / temp.
Ana iya zaɓar fitarwar sarrafa PID don auna CO2
Fitowar gudun ba da sanda guda ɗaya na zaɓi ne.Yana iya sarrafa fanko ko janareta na CO2.Ana zaɓi yanayin sarrafawa cikin sauƙi.
LED mai launi 3 yana nuna matakan matakan CO2 guda uku
Allon OLED na zaɓi yana nuna ma'aunin CO2/Temp/RH
Ƙararrawar Buzzer don samfurin sarrafawar gudun ba da sanda
Hanyoyin sadarwa na RS485 tare da Modbus ko BACnet yarjejeniya
