Chinyezi cha nthaka:
Mtundu wamagetsi (0 ~ 5V kutulutsa):
R = V / 5 × 100%
(R ndiye chinyezi cha nthaka ndipo V ndi mtengo wamagetsi otulutsa (V))
Mtundu wapano (4 ～ 20mA zotuluka):
R = (I-4) / 16 × 100%
(R ndiye kuchuluka kwa chinyezi cha nthaka, ine ndiye mtengo wapano (mA))

Kutentha kwa nthaka:
Mtundu wamagetsi (0 ~ 5V kutulutsa):
T = V / 5 × 70-20
(T ndiye mtengo woyezera kutentha (℃), V ndi mtengo wamagetsi otulutsa (V), fomula iyi imafanana ndi muyeso woyezera -20 ~ 50 ℃)
Mtundu wapano (4 ～ 20mA)
T = (I-4) / 16 × 70 -20
(T ndiye muyeso woyezera kutentha (℃), Ine ndiye kutulutsa panopa (mA), fomulayi imagwirizana ndi muyeso woyezera -20 ～ 50 ℃)

1.Ngati muli ndi malo opangira nyengo opangidwa ndi kampaniyo, gwirizanitsani kachipangizo kameneka ndi mawonekedwe ogwirizana pa siteshoni ya nyengo pogwiritsa ntchito chingwe cha sensa;

2. Ngati transmitter igulidwa padera, mzere wofananira wa transmitter ndi:

Magetsi a Transmitter ndi mawaya aposachedwa:

Wiring kwa ma voltage output mode

Wiring kwa panopa linanena bungwe mode

Kapangidwe Miyeso

Kuti muwerengere nambala ya CRC:
1.Kaundula wa 16-bit wokonzedweratu ndi FFFF mu hexadecimal (ndiko kuti, onse ndi 1).Imbani kaundulayu kuti kaundula wa CRC.
2.XOR deta yoyamba ya 8-bit yokhala ndi cholembera cha 16-bit CRC ndikuyika zotsatira mu kaundula wa CRC.
3.Sinthani zomwe zili m'kaundula kumanja ndi pang'ono pang'ono (kumunsi pang'ono), lembani kachidutswa kakang'ono kwambiri ndi 0, ndipo onani chotsikitsitsa.
4.Ngati chocheperako ndi 0: bwerezani gawo 3 (sinthaninso), ngati chocheperako ndi 1: kaundula wa CRC ndi XORed ndi polynomial A001 (1010 0000 0000 0001).
5.Bwerezani masitepe 3 ndi 4 mpaka 8 kumanja, kuti deta yonse ya 8-bit yasinthidwa.
6.Bwerezani masitepe 2 mpaka 5 kuti mukonzenso 8-bit data.
7.Regista ya CRC yomwe idapezedwa ndi CRC code.
8.Zotsatira za CRC zikayikidwa muzithunzi zachidziwitso, ma bits apamwamba ndi otsika amasinthidwa, ndipo otsika amakhala oyamba.

Lumikizani sensa molingana ndi malangizo mu njira yolumikizira ma waya, kenaka ikani zikhomo za sensa m'nthaka kuti muyese chinyezi, ndikuyatsa mphamvu ndi chosinthira kuti mupeze kutentha kwa nthaka ndi chinyezi pamalo oyezera.

1.Chonde yang'anani ngati zoyikazo sizili bwino ndikuwona ngati mtundu wa malondawo ukugwirizana ndi zomwe zasankhidwa.
2.Osalumikizana ndi magetsi, ndiyeno yatsani mukayang'ana mawaya.
3.Osasintha mosasamala zinthu kapena mawaya omwe adagulitsidwa pamene katunduyo achoka kufakitale.
4.Sensa ndi chipangizo cholondola.Chonde musamasule nokha kapena kukhudza pamwamba pa sensa ndi zinthu zakuthwa kapena zakumwa zowononga kuti mupewe kuwononga chinthucho.
5.Chonde sungani satifiketi yotsimikizira ndi satifiketi yogwirizana, ndipo mubwezereni ndi katunduyo pokonza.

1.Zotsatira zikapezeka, chiwonetserochi chikuwonetsa kuti mtengo wake ndi 0 kapena wachoka.Onani ngati pali chotchinga kuchokera kuzinthu zakunja.Wosonkhanitsa sangathe kupeza zambiri molondola chifukwa cha vuto la waya.Chonde onani ngati mawayawo ali olondola komanso olimba;
2. Ngati sizili zifukwa zomwe zili pamwambazi, chonde lemberani wopanga.
