Thermocouples anoshandiswa zvakanyanya se tembiricha sensor zvinhu mumaindasitiri nesainzi zvikumbiro nekuda kwekusimba kwavo, yakakura tembiricha huwandu, uye nekukurumidza kupindura nguva.Nekudaro, dambudziko rakajairika ne thermocouples kudiwa kwekutonhora junction muripo. Iyo Thermocoupleinogadzira voltage inoenzanirana nemusiyano wetembiricha pakati pekuyeresa kwayo (kupisa kunopisa) uye kumagumo kwayo (inotonhora kupera).Iyo referensi junction inowanzowanikwa pane yekuisa terminal yechiyereso chiridzwa, uye tembiricha yayo inogona kuchinjika nekuda kwemamiriro ekunze.Kuchinja uku mukutonhora kwekusangana kwejoni kunogona kukonzera kukanganisa kuyerwa kwetembiricha.
Cold junction compensation ndiyo nzira yekuyera chaizvo tembiricha inotonhora yejoni uye kubhadharira mhedzisiro yayo pane thermocouple voltage inobuda.Izvi zvakakosha kuti uwane kuyerwa kwetembiricha kwakaringana, kunyanya mumaapplication anoda kunyatso kudzora tembiricha.Kuita muripo wekutonhora wekusangana kwakakosha kuti uve nechokwadi chechokwadi uye kuvimbika kweyero yetembiricha yethermocouple.Pasina muripo wakafanira, zvikanganiso zvakakura zvinogona kuitika mukuverenga tembiricha, kunyanya munzvimbo dzine tembiricha isina kugadzikana.
Pane nzira dzakati wandei dzekuwana muripo wekutonhora junction, imwe nzira yakajairika ndeye kushandisa thermocouple sign conditioner.Zvishandiso izvi zvakagadzirirwa kuyera kutonhora kwejoni uye kupa muripo unodiwa weiyo thermocouple voltage kubuda.Signal conditioners inogona kuitwa seyakamira-yega mayuniti kana kubatanidzwa muzviridzwa zvekuyeresa.Signal conditioning padhuze neinotonhora junction inogona kushandiswa kuderedza zvikanganiso muzviyero zvetembiricha pamwe nekushandisa yakatsaurirwa siginecha conditioner.Nekushandisa nzira dzakakodzera dzekusefa uye dzekusimudzira padyo nenzvimbo inotonhora, iyo thermocouple voltage inobuda inogona kugadziridzwa kudzikisa mhedzisiro yekutonhora junction tembiricha.
Shanghai Wangyuan Instruments of Measurement Co., Ltd. iChinese yepamusoro-tech bhizinesi level kambani inoshanda mumaindasitiri maitiro ekudzora tekinoroji uye zvigadzirwa kweanopfuura makore makumi maviri.Tinogona kugovera zvakarurama uye zvakavimbikatembiricha transmittersine zvinonzwa zvinhu zveinotonhora junction inotsiva thermocouple pamwe cheteakangwara kuchengetedza chipingamupinyiine otomatiki inotonhora junction muripo basa.Inzwa wakasununguka kutibata kuti uwane rumwe ruzivo.
