2.1 Tsanangudzo yakagadziriswa
Rusvingo rwakaiswa mhando: dhirowa gomba rekuisa pamadziro, shandisa 8mm × 100mm bhaudhi yekuwedzera, gadzirisa bhaudhi rekuwedzera pamadziro, isa transmitter, wozoigadzirisa nenati, elastic pad uye flat pad, sezvakaratidzwa mumufananidzo 2.
Mushure mekunge iyo transmitter yagadziriswa, bvisa chivharo chepamusoro uye tungamira mutambo kubva mukupinda.Batanidza terminal zvinoenderana nechakanaka uye nechakaipa polarity (Ex type connection inoratidzwa mudhayagiramu) sezviri kuratidzwa mumufananidzo wekudhirowa, wozokiya mubatanidzwa usingapindi mvura, wosunga kavha yekumusoro mushure mekunge malink ese atariswa kuti akarurama.
Ongorora: iyo sensor inofanirwa kunge iri pasi panguva yekuiswa.

2.2 Wiring mirayiridzo
2.2.1 RS485 maitiro
(1) Cables ichave rvvp2 * 1.0 uye pamusoro, maviri 2-core waya kana rvvp4 * 1.0 uye pamusoro, uye imwe 4-core waya.
(2) Iyo wiring inongotsigira ruoko-mu-ruoko nzira.Mufananidzo 3 unoratidza iyo yakazara wiring dhizaini, uye Mufananidzo 4 inoratidza yakadzama yemukati wiring dhizaini.
Mufananidzo 3 yakazara wiring diagrams
(1) Kupfuura 500m, inoda kuwedzera inodzokorora.Uye zvakare, kana iyo transmitter yakabatana yakawandisa, iyo switching magetsi inofanirwa kuwedzerwa.
(2) Inogona kubatanidzwa nebhas control cabinet kana PLC, DCS, etc. Modbus communication protocol inodiwa kubatanidza PLC kana DCS.
(3) Kune iyo terminal transmitter, shandura dzvuku toggle switch pane transmitter kuenda kune kwakananga.

(1) Tambo ichave RVVP3 * 1.0 uye pamusoro, 3-core waya.
Mufananidzo 5 4-20mA kubatana
Iyo chiridzwa inogona kuratidza pane imwechete gasi kukosha index.Kana iyo index yegesi ichaonekwa iri mu alarm range, relay ichavharwa.Kana mwenje weruzha uye nemwenje wemwenje ukashandiswa, ruzha uye mwenje alarm inotumirwa kunze.
Chiridzwa chine matatu maratidziro emwenje uye imwe LCD switch.
Chiridzwa chine basa rekuchengetedza-nguva chaiyo, iyo inogona kurekodha iyo alarm mamiriro uye nguva munguva chaiyo.Ndokumbira utarise kune iyo inotevera mirairo yekushanda uye tsananguro yebasa.

3.2 Ratidza interface
Mushure mekunge chiridzwa ichi chaiswa simba, pinda iyo bhutsu yekuratidzira interface.Sezvinoratidzwa Mufananidzo 7:
Mufananidzo 7 bhutsu inoratidzira interface
Iyi interface ndeyekumirira kuti chiridzwa paramita dzigadzikane.Iyo scroll bar iri pakati peLCD inoratidza nguva yekumirira, ingangoita makumi mashanu.X% ndiko kufambira mberi kwekumhanya kwazvino.Mukona yekurudyi yekona yekuratidzira ndiyo nguva yechiridzwa chiripo (ino nguva inogona kuchinjwa sezvinodiwa mumenyu).
Kana nguva yekumirira iri 100%, chiridzwa chinopinda chekutarisa gasi kuratidza interface.Tora kabhoni monoxide semuenzaniso, sezvakaratidzwa Mufananidzo 8.
Mufananidzo 8 yekutarisa gasi kuratidza
Kana uchida kuona gasi parameters, tinya kurudyi kiyi.
1) Kuonekwa kwekuratidzira interface:
Ratidza: rudzi rwegasi, kukosha kwegasi, chikamu, nyika.Sezvinoratidzwa Mufananidzo 8.
Kana gasi radarika chinangwa, mhando yearamu yeyuniti icharatidzwa kumberi kwechikamu (rudzi rwearamu yecarbon monoxide, hydrogen sulfide uye gasi rinopisa riri nhanho 1 kana nhanho 2, nepo mhando yearamu yeokisijeni ndiyo muganhu wepamusoro kana wepasi), sezvinoratidzwa mumufananidzo 9.
Mufananidzo 9 interface ine gasi alarm
1) Parameter kuratidza interface:
Mune gasi yekuona interface, tinya-kurudyi kuti upinde mugasi parameter kuratidza interface.
Ratidza: rudzi rwegasi, alarm state, nguva, yekutanga nhanho alarm kukosha (yakaderera muganho alarm), yechipiri nhanho alarm kukosha (yepamusoro muganho alarm), renji, ikozvino gasi rekuisa kukosha, unit, gasi chinzvimbo.
Paunenge uchidzvanya kiyi (kiyi yekurudyi) pasi pe "kudzoka", iyo yekuratidzira inoshandura kune yekuona gasi kuratidza interface.
