1)4 ~ 20mChizindikiro chokhazikika, chothandizira HART protocol
Mapangidwe opepuka, ma waya atatu (4 ~ 20)mChizindikiro chokhazikika, chogwiritsa ntchito sensa yoyamba yotumizidwa kunja, yothandizira protocol ya HART
2)Ma module apamwamba kwambiri ophatikizidwa
Sensor module imaphatikiza sensa ndi gawo lokonzekera, kuti amalize ntchito yonse ya data ndi kusintha kwa chizindikiro kwa chowunikira paokha. Kutentha kwake kwapadera kumakulitsa luso la chowunikira chotsika. The detector module ndi yamagetsi, kulankhulana ndi ntchito zotuluka;
3)Kutetezedwa kopitilira muyeso kwa ndende yayikulu
Pakachulukirachulukira kwa gasi wambiri, gawo la sensa limatha kutsitsa mphamvu zokha. Kuzindikira kumagwira ntchito 30s iliyonse mpaka ndende ili bwino ndipo magetsi ayambiranso. Ntchitoyi ingalepheretse kuchepetsa moyo wautumiki wa sensa chifukwa chomizidwa mu mpweya wochuluka;
4)Mawonekedwe a digito okhazikika
Mawonekedwe a digito amagwiritsidwa ntchito pakati pa ma module. Anti-misplug-yokutidwa ndi golide mapini ndi abwino m'malo mwa pulagi yotentha pamalopo;
5)Kuphatikiza kosinthika komanso mitundu ingapo yotulutsa
Ma module angapo ojambulira ndi mitundu ingapo ya ma module a sensa amatha kuphatikizidwa mosavuta kuti apange zowunikira zomwe zimakhala ndi ntchito zapadera zomwe zimagwiritsidwa ntchito pazolinga zosiyanasiyana kuti zikwaniritse zofuna za makasitomala;
6)Sinthani sensa mosavuta ngati kuyika babu
Ma module a sensa amitundu yosiyanasiyana ya gasi ndi magawo amatha kusinthidwa momasuka. Palibe calibration chofunika pambuyo m'malo. Ndiye kuti, chojambuliracho chimatha kuwerenga zomwe zidasinthidwa kale kufakitale ndikugwira ntchito nthawi yomweyo. Mwanjira imeneyi, mankhwalawa amakhala ndi moyo wautali wautumiki. Pakadali pano, kuwongolera kuzindikira kumatha kuchitika mosavuta pamasamba osiyanasiyana, kupewa njira zovuta zothamangitsira komanso kusanja kwapamalo ndikuchepetsa mtengo wokonzanso pambuyo pake.;
7)Mawonekedwe amtundu wa LED pamasamba, ndi mitundu yosiyanasiyana ya ma calibration
Onetsani chiwonetsero cha nthawi yeniyeni ya LED, yokhala ndi mtunda wowoneka bwino komanso wokulirapo, womwe umagwirizana ndi zofunikira za chilengedwe cha mafakitale; detector ikhoza kukhazikitsidwa / kuyesedwa m'njira zosiyanasiyana, monga makiyi kapena ndi IR remote controller kapena maginito bar, ndipo ndi yosavuta kugwira ntchito;
8)Mapangidwe osaphulika
Ekutsekedwa kwa chinthu ichi kumapangidwa ndi aluminiyamu kapena zitsulo zosapanga dzimbiri ndipo kalasi yake yotsimikizira kuphulika imafikaExd II CT6 Gb.
