I-PR293 Series Nanovolt Microhm Thermometer (2)

Ii-thermometers ze-PR291 series microhm kunye nee-PR293 series nanovolt microhm thermometers zizixhobo zokulinganisa ezichanekileyo kakhulu ezenzelwe ngokukodwa i-metrology yobushushu. Zifanelekile kwimisebenzi emininzi, njengokulinganisa idatha yobushushu ye-sensor yobushushu okanye idatha yombane, uvavanyo lokufana kobushushu bee-oven zokulinganisa okanye iibhafu, kunye nokufunyanwa kwesignali yobushushu kunye nokurekhoda iitshaneli ezininzi.

Njengoko isisombululo sokulinganisa singcono kune-7 1/2, xa kuthelekiswa nee-multimeters zedijithali ezichanekileyo kakhulu, eziye zasetyenziswa kakhulu kwi-metrology yobushushu ixesha elide, kukho uyilo oluninzi olulungiselelweyo ngokwemida, umsebenzi, ukuchaneka, kunye nokulula kokusetyenziswa ukwenza inkqubo yokulinganisa ubushushu ichaneke ngakumbi, ilula kwaye ikhawuleze.

Iimbonakalo

Ubungakanani bovakalelo lwe-10nV / 10μΩ

Uyilo oluphambili lwe-amplifier yengxolo ephantsi kakhulu kunye nemodyuli yombane ophantsi we-ripple iyanciphisa kakhulu ingxolo yokufunda yeluphu yesignali, ngaloo ndlela inyusa uvakalelo lokufunda ukuya kwi-10nV/10uΩ, kwaye inyusa ngempumelelo amanani okubonisa asebenzayo ngexesha lokulinganisa ubushushu.

Uzinzo oluhle kakhulu lonyaka

Iithermometha zePR291/PR293 zothotho, ezisebenzisa umgaqo wokulinganisa umlinganiselo kunye neeresistor ezisemgangathweni zereferensi ezakhelwe ngaphakathi, zine-coefficient yobushushu ephantsi kakhulu kunye nozinzo oluhle kakhulu lonyaka. Ngaphandle kokusebenzisa umsebenzi wereferensi yobushushu obungaguqukiyo, uzinzo lonyaka lothotho lonke lusenokuba ngcono kakhulu kune-7 1/2 digital multimeter esetyenziswa rhoqo.

Iskena esidityanisiweyo esineetshaneli ezininzi ezinengxolo ephantsi

Ukongeza kwitshaneli engaphambili, kukho iiseti ezizimeleyo ezi-2 okanye ezi-5 zeetheminali zovavanyo ezisebenza ngokupheleleyo ezidityaniswe kwiphaneli engasemva ngokweemodeli ezahlukeneyo kwiithemometha zePR291/PR293 series. Itshaneli nganye inokuseta ngokuzimeleyo uhlobo lwesignali yovavanyo, kwaye inokuhambelana okuphezulu kakhulu phakathi kweetshaneli, ngoko ke ukufunyanwa kwedatha yetshaneli ezininzi kunokwenziwa ngaphandle kokutshintsha kwangaphandle. Ukongeza, uyilo lwengxolo ephantsi luqinisekisa ukuba imiqondiso eqhagamshelwe kwiitshaneli ayizisi ingxolo eyongezelelweyo yokufunda.

Imbuyekezo ye-CJ echanekileyo kakhulu

Ukuzinza nokuchaneka kobushushu be-CJ kudlala indima ebalulekileyo ekulinganisweni kwee-thermocouples ezichanekileyo kakhulu. Iimitha zedijithali ezichanekileyo kakhulu ezisetyenziswa rhoqo kufuneka zidityaniswe nezixhobo ezikhethekileyo ze-CJ zokulinganisa i-thermocouple. Imodyuli ye-CJ echanekileyo kakhulu edityaniswe kwii-thermometers ze-PR293 series, ngoko ke impazamo ye-CJ yetshaneli esetyenzisiweyo engcono kune-0.15℃ ngaphandle kwezinye izinto ezisetyenziswayo inokufezekiswa.

Imisebenzi yokulinganisa ubushushu obutyebileyo

Iithermometha zothotho lwePR291/PR293 zizixhobo zovavanyo ezikhethekileyo ezenzelwe imboni yemetrology yobushushu. Kukho iindlela ezintathu zokusebenza zokufumana, ukulandelela itshaneli enye, kunye nokulinganisa umahluko wobushushu, apho imo yokulinganisa umahluko wobushushu inokuhlalutya ukufana kobushushu kuzo zonke iintlobo zezixhobo zobushushu ezingaguqukiyo.

Xa kuthelekiswa ne-multimeter yedijithali yendabuko, kongezwa uluhlu lwe-30mV ngokukodwa lokulinganisa ii-thermocouples zohlobo lwe-S kunye noluhlu lwe-400Ω lokulinganisa ukumelana kweplatinum ye-PT100. Kwaye ngeenkqubo zokuguqula ezakhelwe ngaphakathi zeenzwa ezahlukeneyo zobushushu, iintlobo ngeentlobo zeenzwa (ezifana nee-thermocouples eziqhelekileyo, ii-thermometers eziqhelekileyo zokumelana neplatinum, ii-thermometers zokumelana neplatinum yezimboni kunye nee-thermocouples ezisebenzayo) kwaye idatha yesatifikethi okanye idatha yokulungisa inokubhekiswa ukulandelela ubushushu beziphumo zovavanyo.

Umsebenzi wohlalutyo lwedatha

Ukongeza kwiidatha ezahlukeneyo zovavanyo, ii-curves kunye nokugcinwa kwedatha kunokuboniswa, idatha yexesha langempela ephezulu/ubuncinci/ixabiso eliphakathi, idatha eyahlukeneyo yozinzo lobushushu inokubalwa, kwaye idatha ephezulu kunye neyona incinci inokuphawulwa ukuze kube lula uhlalutyo lwedatha oluqondakalayo kwindawo yovavanyo.

Uyilo oluphathekayo

Iimitha zedijithali ezichanekileyo kakhulu ezisetyenziswa kakhulu kwiilabhoratri zihlala zinkulu kwaye azithwali mpahla. Ngokwahlukileyo koko, ii-thermometers ze-PR291/PR293 zincinci ngomthamo nangobunzima, nto leyo elungele uvavanyo lobushushu obuphezulu kwiindawo ezahlukeneyo kwindawo. Ukongeza, uyilo lwebhetri ye-lithium enkulu eyakhelwe ngaphakathi lwenza inkqubo yokusebenza ibe lula.
