Voltage mhando (0～5V):
T=V / 5 × 70 -20
(T ndiyo yakayerwa tembiricha kukosha (℃), V ndiyo inobuda magetsi (V), iyi fomula inoenderana nechiyero chechiyero -20 ~ 50 ℃)
T=V / 5 × 150 -50
(T ndiyo yakayerwa tembiricha kukosha (℃), V ndiyo inobuda magetsi (V), iyi fomula inoenderana nechiyero chekuyera -50 ~ 100 ℃)
Yazvino mhando (4～20mA)
T = (I-4)/ 16 × 70 -20
(T ndiyo yekuyera kukosha kwekushisa (℃), ini ndiri kubuda ikozvino (mA), rudzi urwu runoenderana nechiyero chekuyera -20 ~ 50 ℃)
T=(I-4)/ 16 × 150 -50
(T ndiyo yakayerwa kukosha kwetembiricha (℃), ini ndiri kubuda ikozvino (mA), iyi fomula inoenderana nechiyero chechiyero -50 ~ 100 ℃)
Ongorora: Iwo maformula ekuverenga anoenderana neakasiyana masaini mabudiro uye akasiyana kuyerwa zviyero zvinoda kuverengerwazve!
1.Kana yakashongedzerwa nechiteshi chemamiriro ekunze chakagadzirwa nekambani yedu, batanidza zvakananga sensor kune inoenderana interface pane yemamiriro ekunze chiteshi uchishandisa sensor tambo.
2. Kana iyo transmitter yakatengwa yakaparadzana, iyo inoenderana netambo kutevedzana kweiyo transmitter ndeye:

Kuverenga iyo CRC kodhi:
1. Iyo preset 16-bit rejista ndeye FFFF mune hexadecimal (kureva, ese ari 1).Fonera rejista iyi kurejista yeCRC.
2.XOR yekutanga 8-bit data ine yakaderera bhiti re16-bit CRC register uye isa mhedzisiro muCRC rejista.
3.Chinja zviri mukati merejista kurudyi nebhiti rimwechete (kunanga kune yakaderera), zadza iyo yepamusoro bhiti ne0, uye tarisa yakaderera.
4.Kana iyo isinganyanyi kukosha iri 0: dzokorora nhanho 3 (chinja zvakare), kana iyo isinganyanyi kukosha iri 1: iyo CRC regisheni iri XORed ine polynomial A001 (1010 0000 0000 0001).
5. Dzokorora nhanho 3 uye 4 kusvika kasere kurudyi, kuitira kuti iyo yese 8-bit data yagadziriswa.
6. Dzokorora nhanho 2 kusvika ku5 kune inotevera 8-bit data kugadzirisa.
7.Rejista yeCRC yakazowanikwa ndiyo CRC kodhi.
8. Kana iyo CRC mhedzisiro yaiswa mune yeruzivo furemu, iyo yakakwirira uye yakaderera mabhiti anotsinhaniswa, uye yakaderera bhiti ndiyo yekutanga.
Batanidza sensor maererano nemirayiridzo mune nzira ye wiring, uye wozoisa iyo sensor probe muvhu kuyera tembiricha, uye upe simba kune muunganidzi uye sensor kuti uwane tembiricha yemvura panzvimbo yekuyera.
1. Ndokumbira utarise kana kurongedza kwacho kwakamira uye tarisa kana iyo chigadzirwa modhi inoenderana nesarudzo.
2. Usabatana nemagetsi, wobva wabatidza mushure mekutarisa wiring.
3. Usaite zvehumbimbi kushandura zvikamu kana waya dzakatengeswa kana chigadzirwa chabva mufekitari.
4.Iyo sensor ndeye chaiyo mudziyo.Ndokumbira urege kuibvisa uri wega kana kubata pamusoro pe sensor nezvinhu zvakapinza kana zvinopisa zvinwiwa kuitira kudzivirira kukuvadza chigadzirwa.
5. Ndokumbira uchengete chitupa chekusimbisa uye chitupa chekuenderana, uye chidzose nechigadzirwa paunenge uchigadzira.
1.Kana izvo zvabuda zvaonekwa, chiratidziro chinoratidza kuti kukosha kwacho kuri 0 kana kuti kwave kunze.Tarisa kuti pane kuvharika kubva kune zvimwe zvinhu.Muunganidzi anogona kutadza kuwana ruzivo nemazvo nekuda kwezvinetso zvewaya.Ndokumbira utarise kana wiring yakarurama uye yakasimba.
2.Kana zvisiri zvikonzero zviri pamusoro, ndapota taura nemugadziri.
