XDB702 PT100 Sensor Kutentha: Kumvetsetsa Njira Zosiyanasiyana za Wiring

Masensa a kutentha kwa PT100 amagwiritsidwa ntchito kwambiri m'mafakitale odzipangira okha ndi machitidwe olamulira kuti athe kuyeza kutentha molondola komanso modalirika.XDB702 PT100 sensor kutentha ndi chipangizo chapamwamba kwambiri chomwe chimapangidwira kusintha zizindikiro za PT100 zotsutsana ndi platinamu kukhala zizindikiro za 4-20mA.M'nkhaniyi, tiwona njira zosiyanasiyana zama waya zomwe zimagwiritsidwa ntchito pa masensa a kutentha kwa PT100.

Masensa a kutentha kwa PT100 amaikidwa mwachindunji mu PT100 platinamu resistance resistance mabokosi, omwe amakhala ndi mitundu yosiyanasiyana ya kukana kwa platinamu yomwe imapanga sensor ya kutentha yophatikizika ya thermoresistance.Masensa awa amasintha ma sign a PT100 platinamu kukhala ma siginecha a 4-20mA.Komabe, masensa a kutentha kwa PT100 akagwiritsidwa ntchito potumiza zizindikiro zakutali za PT100 platinamu kukana, amatha kusokonezedwa kwambiri ndi malo kapena amafuna kulumikizana ndi dongosolo la DCS.

Sensa ya kutentha ya XDB702 PT100 idapangidwa ndi gulu lapadera la magawo awiri osanjikiza, ndi gawo lapansi lomwe limaperekedwa pakusintha kwazizindikiro ndi chapamwamba chomwe chimagwiritsidwa ntchito kudziwa mtundu wa sensa ndi kuchuluka kwake.

Zofunika Kwambiri za XDB702 PT100 Temperature Sensor

Liniya linanena bungwe la 2-waya 4-20mA muyezo panopa chizindikiro, ndi dongosolo modular.

Sensa ya kutentha ya XDB702 PT100 imagwiritsa ntchito zigawo zomwe zatumizidwa kunja, kuonetsetsa kuti ntchito yodalirika ndi yotsika kutentha.

Chipangizocho chimakhala ndi polarity reversal protection circuit, yomwe imateteza dera pamene zotulukazo zimasinthidwa (pamenepo ndi zero).

Chogulitsacho chilinso ndi chitetezo cha RFI/EMI, chomwe chimathandizira kukhazikika kwa muyeso.

Zosiyanasiyana za XDB702 PT100 sensor kutentha sizingasinthidwe mwakufuna, ndipo wopanga yekha ndi amene angatsimikizire zomwe amapanga.

Kugwirizana kwa electromagnetic kwa PT100 sensor kutentha kumagwirizana ndi European Electrical Committee (EC) BSEN50081-1 ndi BSEN50082-1 ​​miyezo.

Wiring Njira za PT100 Kutentha Sensor

Sensa ya kutentha ya PT100 nthawi zambiri imalumikizidwa ndi screw terminal pamwamba pa casing yake.Kuti mukwaniritse zofunikira za certification ya CE, kutalika kwa waya wolowera siginecha sikuyenera kupitirira 3 metres, ndipo mawaya otuluka ayenera kukhala otetezedwa, ndi waya wa chishango cholumikizidwa pansi kumapeto amodzi okha.

Bowo lapakati la sensa limagwiritsidwa ntchito pa waya wa PT100 platinamu kukana, ndipo waya wa PT100 platinamu wokanira amapindika mwachindunji kumapeto kwa sensayo pogwiritsa ntchito screw.Malo opangira screw amatha kugwiritsidwa ntchito ngati mawaya amkati kapena akunja.

Njira imodzi yolumikizira sensor kutentha kwa PT100 ndi motere:

PT100 platinamu resistance sensor ili ndi mawaya atatu: A, B, ndi C (kapena wakuda, wofiira, ndi wachikasu).A ndi B kapena C ali ndi mphamvu yotsutsa yozungulira 110 ohms kutentha kwa firiji, pamene mtengo wotsutsa pakati pa B ndi C uli pafupi ndi 0 ohms, ndi B ndi C zolumikizidwa mkati.Mapeto okhazikika a chida chomwe chimagwirizanitsidwa ndi sensa chimakhala ndi ma terminals atatu: A amagwirizanitsidwa ndi mapeto okhazikika a chida, pamene B ndi C akugwirizanitsidwa ndi malekezero ena awiri osasunthika a chida.B ndi C zikhoza kusinthidwa, koma ziyenera kugwirizana.Ngati waya wotalikirapo agwiritsidwa ntchito pakati pawo, mafotokozedwe ndi kutalika kwa mawaya atatuwo ayenera kukhala ofanana.

PT100 ikhoza kulumikizidwa pogwiritsa ntchito njira za 2-waya, 3-waya, kapena 4-waya, kutengera zida zomwe zimagwiritsidwa ntchito.Zida zowonetsera wamba zimapereka mgwirizano wa 3-waya, ndi mapeto amodzi a PT100 sensa yolumikizidwa ndi waya umodzi ndi mapeto ena ogwirizana ndi mawaya awiri omwe amagwirizanitsidwa ndi chida.Kukana kwa waya wamkati kwa chidacho kumayendetsedwa bwino ndi mlatho.PLCs nthawi zambiri amagwiritsa ntchito 4-waya malumikizidwe, ndi mawaya awiri olumikizidwa ku malekezero aliwonse a PT100 sensa ndi mawaya awiri olumikizidwa kwa zotuluka nthawi zonse gwero la PLC.PLC imayesa voteji pa mawaya ena awiriwa kuti azitha kupirira mawaya.Kulumikiza mawaya anayi ndikolondola kwambiri, pomwe kulumikiza mawaya atatu ndikovomerezeka, ndipo kulumikiza mawaya awiri ndikosavuta kwambiri.Njira yeniyeni yogwiritsiridwa ntchito imadalira kulondola kofunikira ndi mtengo wake.
