Nzira yekutonga sei kana thermocouple yakanaka kana yakaipa?

Iko kushandiswa mukugadzirwa kuri kuwedzera uye kwakawedzera.Thermocouplesdzave chimwe chezvinhu zvinowanzo shandiswa tembiricha yekuona zvikamu mune indasitiri. Ivo vane hunhu hweyakanyanya kuyerwa kurongeka, yakafara kuyera renji, yakapusa chimiro, uye nyore kushandisa. Isu tinonzwisisa uye tinoongorora zvigadzirwa kuburikidza nenzira dzakawanda, uye tinopa huwandu hwakawanda hweruzivo rweindasitiri kune vazhinji vevatengesi.
Saka chinotevera tinosvika pakunzwisisa mutongo wekutithermocouple yakanaka here kana yakaipa?
Nheyo yekutanga yeyero yekushisa kwethermocouple ndeyekuti zvikamu zviviri zvakasiyana zvemaconductor emidziyo zvinoumba loop yakavharwa. Kana paine tembiricha yekushisa kumativi ese ari maviri, ikozvino inoyerera nemuchiuno. Panguva ino, pane electromotive force-thermoelectromotive simba pakati pemigumo miviri. Iyi ndiyo inonzi Seebeck effect. Maviri mahomogeneous conductors ezvikamu zvakasiyana arithemoelectrode, kuguma nekushisa kwepamusoro ndiyo kuguma kwekushanda, kuguma nekushisa kwakadzika ndiko kuguma kwekusununguka, uye kuguma kwekusununguka kunowanzove kune imwe nguva yekushisa.
Mushure mekushandisa kwenguva yakati,thermocouples inonyatsopera, uye inogona kutokuvara. Kazhinji, mhando yethermocouples inoenderana neiyothermocouple waya (waya) mairi, asi maitiro ekutonga mhando yeiyothermocouple waya ndiro dambudziko. Ngatikurukurei zvishoma.


Chokutanga pane zvose, iva nechokwadi chokuti hapana dambudziko nechitarisiko chetambo yethermocouple, ingave yakanaka kana yakaipa, uye inogona kugadziriswa chete nekuedzwa.
Isa tambo yethermocouple kuti iongororwe pane yakakosha sleeve sleeve yeiyothermocouple, woiisa muchoto chemagetsi chetubular pamwe chete neplatinum nerhodiumthermocouple, woisa mugumo unopisa muchoto chesimbi chinonyorova muchoto chemagetsi chetubula. Muhumburumbira. Isa magumo anotonhora ewaya dzemuripo mugaba rine zero madhigirii Celsius anochengetwa nemusanganiswa weaizi nemvura.
Chengeta iyo yemagetsi chubhu yevira padanho rinobvumidzwa tembiricha yeiyothermocouple, uye chengetedza iyi renji zvakadzikama. Panguva ino, shandisa anokwanisa Wheatstone potentiometer kuyera uye kurekodha iyo thermoelectric inogona mutsauko pakati peyakajairwathermocouple uye iyothermocouple ichaedzwa. Zvinoenderana neyakarekodhwa thermoelectric mukana wemusiyano, tarisa tafura ye index kuti uone tembiricha inoenderana. Kana iyothermocouplepasi pekuyedzwa kuri kunze kwekushivirira, inogona kutongwa seisina kukodzera.
