Bambanci tsakanin Thermocouple da Thermal Resistance (RTD)

Abokai da yawa suna tambaya ko thermocouple da RTD na'urar iri ɗaya ce, amsar da ta dace ba na'urar iri ɗaya ba ce. Kodayake ana amfani da duka thermocouples da RTDS azaman abubuwan gano zafin jiki, ƙa'idodinsu, dalilai, da kewayon zafin jiki sun bambanta.

Rarraba hanya 1: bisa ga tsarin don bambanta tsakanin thermocouples ko RTDs, thermocouples gabaɗaya sun ƙunshi na'urorin zafi, bututu masu rufewa, hannayen riga da akwatunan junction da sauran sassan, RTDs sune fitarwa na nauyin firikwensin kuma ana haɗa wutar lantarki a ciki. jerin.

Rarraba hanyar 2: bisa ga lakabin don sanin ko yana da thermocouple ko RTD, farantin suna zai zama takamaiman thermocouple ko RTD takamaiman samfura da ƙayyadaddun bayanai, kawai muna buƙatar lura da hankali da rarrabe tsakanin thermocouples ko RTDs za a iya bambanta.

Rarraba hanyar 3: ta hanyar toshe tashoshi don tantancewa, akwai tabbataccen ra'ayi mai kyau da mara kyau shine thermocouple, babu bambanci mai kyau da mara kyau shine RTD. Wannan hanyar rarrabewa tana da sauƙi mai sauƙi, zaku iya gwada oh.

Rarraba hanyar 4: ta hanyar layin ramuwa don yin hukunci, thermocouple yana buƙatar zaɓar layin ramuwa daban-daban bisa ga nau'ikan nau'ikan daban-daban, haɗa layin ramuwa don haɓaka kwanciyar hankali na thermocouple, kuma RTD baya buƙatar waya diyya, amma RTD kuma ya kasu kashi biyu. daban-daban model.

Thermocouple da RTD abubuwa ne daban-daban guda biyu, muna buƙatar rarrabewa a hankali, kar a yi kuskure, muna buƙatar bayyanawa game da abubuwan da suke buƙatar yin a ƙarshe, gwargwadon ainihin bukatunsu, zaɓi RTD ko thermocouple daidai da. ainihin yanayin su, ƙarin game da thermocouple na sabbin bayanai, za a sabunta mu akai-akai.
