Plne v súlade s predpismi ATEX.
Výbušné prostredie je potrebné chrániť pred zdrojmi ohňa. Nevyhnutnosťou je voľba zariadení a ochranných systémov, ktoré spĺňajú požiadavky nariadenia ATEX alebo podobných predpisov.
Kamera A310 ex je v súlade s riešením ATEX, s termovíznou kamerou umiestnenou v kryte, aby bolo možné monitorovať kritický a taktiež ďalší cenný majetok v prostredí s nebezpečenstvom výbuchu. Medzi typické aplikácie pre A310 ex patrí monitorovanie procesov, kontrola kvality a detekcia požiaru vo výbušných prostrediach. Vzhľadom k tomu, že A310 ex má ochranu IP67, môže byť inštalovaná v prašnom prostredí.
Ohňu vzdorný kryt zabraňuje prenosu výbuchu z vnútra krytu von.
Vlastnosti
Integrovaný radič
Integrovaný radič obsahuje niekoľko digitálnych I/O kanálov a senzorov pre teplotu, vlhkosť a tlak. Medzi inými funkciami, I/O kanály umožňujú užívateľovi zapnúť alebo vypnúť kameru a ohrev diaľkovým ovládaním. Prístup sa uskutočňuje prostredníctvom integrovaného webového rozhrania alebo Modbus TCP/IP. Integrovaný radič je vybavený dvoma optickými vláknami a dvoma ethernetovými časťami. To umožňuje flexibilné zapojenie siete do hviezdy alebo kruhu.
Ohrievač
Kamera A310 ex je dodávaná s ohrievačom, ktorý účinne zabraňuje zahmlievaniu a zamrazovaniu ochranného okienka.
Certifikát
Kamera A310 ex má ATEX certifikáciu (ZELM 12 ATEX 0485 X). Môže byť teda inštalovaná v klasifikačných zónach 1, 2, 21 a 22. Certifikácia zahŕňa celý systém, ktorý zahŕňa kryt ako aj všetky komponenty vo vnútri, ako napríklad termovízne kamery, ohrievač a integrovaný radič.
