PH Sensor
Iyo itsva-chizvarwa PHTRSJ ivhu pH sensor inogadzirisa kukanganisa kwechinyakare ivhu pH iyo inoda nyanzvi yekuratidzira zviridzwa, inonetesa calibration, yakaoma kusanganisa, kushandiswa kwesimba kwakanyanya, mutengo wakakwira, uye zvakaoma kutakura.
●Ivhu idzva pH sensor, inoona online chaiyo-nguva yekutarisa ivhu pH.
●Iyo inotora yakanyanya kusimba yakasimba dielectric uye yakakura-nzvimbo yepolytetrafluoroethylene fluid junction, iyo isiri nyore kuvharira uye kuchengetedza-isina.
●Kubatanidzwa kwepamusoro, hukuru hudiki, kushandiswa kwesimba shoma, nyore kutakura.
●Ziva mutengo wakaderera, mutengo wakaderera uye kushanda kwakanyanya.
●Kubatanidzwa kwepamusoro, hupenyu hurefu, nyore uye kuvimbika kwepamusoro.
●Kushanda kuri nyore.
●Tsigira kusimudzira kwechipiri.
●Iyo electrode inoshandisa yakakwirira-yemhando yakaderera-ruzha tambo, iyo inogona kuita iyo chiratidzo chekubuda kureba kusvika pamamita makumi maviri pasina kukanganisa.
Ichi chigadzirwa chinogona kushandiswa zvakanyanya muminda yekudiridza kwekurima, kurima gadheni maruva, mafuro euswa, kukurumidza kuongorora ivhu, kurimwa kwezvirimwa, kuyedza kwesainzi uye zvichingodaro.

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.
1.Kana iyo sensor ichibva mufekitari, probe inopiwa chivharo chekudzivirira chakajeka, uye yakavakirwa-mukati inodzivirira mvura inodzivirira probe.Paunenge uchishandisa, ndapota bvisa chivharo chekudzivirira, gadzirisa tangi yekusefa uye sensor, uye shandisa tambo yakasungirirwa yetambo yekuputira sefa mu tank resefa.Kudzivirira kusangana kwakananga pakati pevhu uye probe uye kukuvadza probe.Mukushandisa chaiko, ndapota ita shuwa kuti iyo sefa yekugezera uye sefa zvakabatanidzwa zvakasimba.Usabvisa chirongo chesefa nesefa.Isa probe muvhu zvakananga kudzivirira kuita kukuvara kweprobe uye kusagadzirisika.
2. Isai chikamu cheprobe chakatwasuka muvhu.Kudzika kweprobe kunofanirwa kunge kwakavharwa nesefa.Mumamiriro ezvinhu akajairika, pH iri mumhepo iri pakati pe6.2 ne7.8.
3.Mushure mekuviga sensor, dururira imwe mvura yakatenderedza ivhu kuyerwa, kumirira maminetsi mashoma, uye kumirira kuti mvura inyure muprobe, ipapo unogona kuverenga data pachiridzwa.Mumamiriro ezvinhu akajairwa, ivhu harina kwazvakarerekera uye pH iri pakati peAround 7, iyo chaiyo pH kukosha kwevhu munzvimbo dzakasiyana ichave yakasiyana, inofanirwa kutariswa zvinoenderana nemamiriro chaiwo.
4.Mushandisi anogona kushandisa zvakanamirwa 3 pH reagents uye gadzirisa zvinoenderana neiyo yekumisikidza nzira yekutarisa kana kuita kwechigadzirwa kwakajairika.
1. Mupombi kuitira kuti ive nechokwadi chekuti electrode yakayerwa yakayerwa pH kukosha kunofanirwa kudziviswa panguva yekuyerwa kwemabhuru emhepo anokonzerwa nedata risiri chairo;
2. Ndokumbira utarise kana kurongedza kwacho kwakamira uye tarisa kana iyo chigadzirwa modhi inoenderana nesarudzo;
3. Usabatana nemagetsi, wobva wabatidza mushure mekutarisa wiring.
4. Usaite zvehumbimbi kushandura zvikamu kana waya dzakatengeswa kana chigadzirwa chabva mufekitari.
5. Iyo sensor ndeye chaiyo mudziyo.Ndokumbira urege kuibvisa uri wega kana kubata pamusoro pe sensor nezvinhu zvakapinza kana zvinopisa zvinwiwa panguva yekushandiswa kudzivirira kukuvadza chigadzirwa.
6.Ndokumbira uchengete chitupa chekusimbisa uye chitupa chekuenderana, uye chidzose nechigadzirwa paunenge uchigadzira.
1.Nekubuda kweanalogi, chiratidziro chinoratidza kuti kukosha kwacho kuri 0 kana kuti kwabuda.Muunganidzi anogona kutadza kuwana ruzivo nemazvo nekuda kwezvinetso zvewaya.Ndokumbira utarise kuti wiring ndeyechokwadi uye yakasimba, uye magetsi emagetsi akajairika;
2.Kana zvisiri zvikonzero zviri pamusoro, ndapota taura nemugadziri.
1.Mhedziso yekupinza yechiridzwa (yekuyeresa electrode socket) inofanira kuchengetwa yakaoma uye yakachena kudzivirira guruva nemhute yemvura kupinda.
2. Dzivisa kunyudzwa kwenguva refu kwemaelectrodes muprotein solution uye acid fluoride solution, uye dzivisa kusangana nesilicone mafuta.
3.Mushure mekushandiswa kwenguva refu kwe electrode, kana mutserendende wakaderedzwa zvishoma, kumucheto kwepasi kwe electrode kunogona kunyudzwa mu 4% HF solution (hydrofluoric acid) kwemasekonzi matatu kusvika ku5, yozogezwa nemvura yakadirwa yobva yanyudzwa mukati. 0.1mol / L hydrochloric acid Zorora iyo electrode.
4.Kuti kuyerwa kuve kwakanyatsojeka, iyo electrode inofanirwa kuverengerwa kazhinji uye kushambidzwa nemvura yakasvibiswa.
5. Iyo transmitter inofanirwa kuiswa munzvimbo yakaoma kana bhokisi rekudzora kudzivirira kudonha kwemamita kana kuyerwa kukanganisa kunokonzerwa nemadonhwe emvura achipfachuka kana kunyorova.
