Ulungelelwaniso kunye noMlinganiselo
YENZA ulungelelwaniso kwiiKhetho
Lungisa ulungelelwaniso
a) Lungisa kwakhona ulungelelwaniso lwe-100%.
Umsebenzisi ubhala 0x0220 = 8
b) Lungisa kwakhona ulungelelwaniso lwe-0%.
Umsebenzisi ubhala 0x0220 = 16
c) Lungisa kwakhona ulungelelwaniso lobushushu.
Umsebenzisi ubhala 0x0220 = 32
I-1-point calibration
Ulungelelwaniso lwe-1-point luthetha ukulungelelanisa iprobe kwindawo ye-100 % saturation, enokufunyanwa ngenye yezi ndlela zilandelayo:
a) Kumanzi azaliswe ngumoya (indlela eqhelekileyo).
Amanzi azaliswe ngumoya (umzekeloampI-le ye-500 mL) inokufumaneka ngokuqhubekayo (1) ngokucocwa kwamanzi ngomoya kusetyenziswa i-bubbler yomoya okanye uhlobo oluthile lokuphefumla malunga nemizuzu emi-3 ukuya kwemi-5, okanye (2) ukushukumisa amanzi ngemagnethi ashukumisayo phantsi kwe-800 rpm iyure enye.
Emva kokuba amanzi agcwele umoya elungile, ntywilisela i-sensor cap kunye ne-sensor yeqondo lokushisa kwi-probe emanzini agcwele umoya, kwaye ulungelelanise i-probe emva kokuba ufundo luzinzile (ngokuqhelekileyo 1 ~ 3 imizuzu).
Umsebenzisi ubhala 0x0220 = 1 , emva koko ulinde imizuzwana engama-30.
Ukuba ufundo lokugqibela lwe-0x0102 alukho kwi-100 ± 0.5%, nceda ujonge ukuba ukuzinza kwendawo yovavanyo lwangoku okanye uzame kwakhona.
b) Kumoya ozele ngamanzi (indlela elula).
Kungenjalo, ulungelelwaniso lwe-1-pt lunokwenziwa lula kusetyenziswa umoya ozele ngamanzi, kodwa impazamo ye-0 ~ 2% inokubangelwa ngokuxhomekeke kwimisebenzi eyahlukeneyo. Iinkqubo ezicetyiswayo zinikwe ngolu hlobo lungezantsi:
i) ntywilisela i-sensor cap kunye ne-sensor yobushushu beprobe emanzini amatsha / epompo 1 ~ 2 imizuzu.
ii) khupha iprobe kwaye ngokukhawuleza udiphe womise amanzi kumphezulu wesensor cap ngethishu.
iii) faka isiphelo senzwa kwi-calibration / ibhotile yokugcina kunye nesiponji esimanzi ngaphakathi. Gwema ukudibanisa ngokuthe ngqo kwe-cap ye-sensor kunye nawaphi na amanzi kwi-calibration / ibhotile yokugcina ngexesha le nyathelo lokulinganisa. Gcina umgama phakathi kwe-sensor cap kunye nesiponji esimanzi ngu ~ 2 cm.
v) linda ufundo luzinze (2 ~ 4 imizuzu) uze ubhale 0x0220 = 2.
Ulungelelwaniso lwamanqaku ama-2 (i-100% kunye ne-0% amanqaku okuzalisa)
(i) Beka iprobe emanzini agcwele umoya, bhala 0x0220 = 1 emva kokuba ufundo lwe-DO luzinzile.
(ii) Emva kokuba ufundo lwe-DO luba yi-100%, hambisa i-probe ku-zero oksijini yamanzi (sebenzisa i-sodium sulfide eyongezwe ngokugqithisileyo
amanzi sample).
(iii) Bhala 0x0220 = 2, emva kokuba ufundo lwe-DO luzinzile (~ ubuncinane imizuzu emi-2).
- (iv) Umlinganiselo wokufunda womsebenzisi ongu-0x0102 wolungelelwaniso lwenqaku eli-1, 0x0104 kulungelelwaniso lwamanqaku ama-2.
I-2-point cal ayiyimfuneko kwizicelo ezininzi, ngaphandle kokuba abasebenzisi bafuna umlinganiselo ochanekileyo kakhulu kwi-concentration ye-DO ephantsi (<0.5 ppm). - Ukunyanzeliswa kwe "0% calibration" ngaphandle kwe "100% calibration" akuvumelekanga.
Indawo yokulinganisa ubushushu
i) Umsebenzisi ubhale 0x000A = iqondo lobushushu le-ambient x100 (Ex: Ukuba iqondo lobushushu le-ambient = 32.15, ngoko umsebenzisi abhale 0x000A=3215).
ii) Ubushushu bokufunda komsebenzisi ku-0x000A. Ukuba ilingana nento oyifakileyo, ulungelelwaniso lwenziwe. Ukuba akunjalo, nceda uzame inyathelo loku-1 kwakhona.
Inkqubo yeModbus RTU
Ulwakhiwo lomyalelo:
- Imiyalelo akufuneki ithunyelwe ngokukhawuleza kuno-50mS ukususela ekugqityweni kwempendulo yokugqibela.
- Ukuba impendulo elindelekileyo kwikhoboka ayibonwa nge> 25mS, phosa impazamo yonxibelelwano.
- Iprobe ilandela umgangatho weModbus kwimisebenzi 0x03, 0x06, 0x10, 0x17
Ubume boThunyelo lothotho:
- Iintlobo zedatha zinkulu-endian ngaphandle kokuba kuphawulwe ngenye indlela.
- Ugqithiso ngalunye lwe-RS485 luya kuba: isiqalo esinye, i-8 bits yedatha, akukho bit parity, kunye ne-stop bits ezimbini;
- Ireyithi yeBaud engagqibekanga: 9600 (ezinye zeeprobes zinokuba neBaudrate ye-19200);
- Idilesi yekhoboka elihlala kukho: 1
- Amasuntswana edatha ayi-8 agqithiselwe emva kwesuntswana lokuqala yeyona nto ibalulekileyo kuqala.
- Ulandelelwano Bit
| Qala kancinci | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | Yeka kancinci |
Ixesha
- Uhlaziyo lweFirmware kufuneka luqhutywe ngaphakathi kwemizuzwana emi-5 yombane okanye usete ngokutsha ngokuthambileyo Ingcebiso ye-LED iya kuba luhlaza okwesibhakabhaka ngeli xesha.
- Umyalelo wokuqala awunakuqhutywa ngaphambi kwemizuzwana eyi-8 ukusuka kumbane okanye ukuseta ngokutsha okuthambileyo
- Ukuba akukho mpendulo ilindelekileyo evela kumyalelo okhutshiweyo ixesha lokuvala lenzeka emva kwe-200ms

UMZOBI WOMLINGANISO WE-MBRTU-PODO (Iyunithi: mm)
Isondlo
Ukugcinwa kweprobe kubandakanya ukucoca i-sensor cap, kunye nokulungiswa okufanelekileyo, ukulungiswa, kunye nokugcinwa kwenkqubo yokuvavanya.
Xa i-probe ingasetyenziswa, kucetyiswa kakhulu ukugcina i-probe kunye ne-sensor cap efakwe kunye ne-calibration / ibhotile yokugcina eyayifakwe kwi-package yasekuqaleni, ifakwe kwi-probe. Ibhekile yamanzi acocekileyo okanye isixhobo sokuvala esifumileyo/ esifumileyo sinokwanela ukuba umlinganiselo/ibhotile yokugcina ayifumaneki. Isiponji esingaphakathi kwebhotile yokulinganisa/yokugcina kufuneka sigcinwe simanzi ukuze ufumane iziphumo ezingcono.
Gwema i-sensor cap echukumisa i-solvent ye-organic, ukukrwela, kunye nokubetha kakubi ukuqinisa kunye nokwandisa ubomi bokusebenza kwe-sensor cap. Ukunyamekela okukhethekileyo kufuneka kuthathwe ukucoca i-coating of cap, ukudipha i-probe kunye ne-cap emanzini amatsha, kwaye emva koko ucofe ukomisa umphezulu ngethishu. Musa ukusula indawo yokwaleka.
Buyisela i-cap ye-sensor cap, ukuba i-cap ye-coating iphelile okanye ihluthwe. SUKUchukumisa ifestile ecacileyo kwincam yeprobe emva kokukhulula ikepusi endala. Ukuba kukho nayiphi na into engcolileyo okanye intsalela ekhoyo kwifestile okanye ngaphakathi kwe-cap, yisuse ngokucophelela nge-powder free wipe. Emva koko phinda ujije i-cap ye-sensor entsha kwi-probe.
