Tele fua alavai
PR291 series microhm thermometers ma PR293 series nanovolt microhm thermometers o meafaigāluega sa'o maualuga e fuaina fa'apitoa mo su'esu'ega o le vevela.E fetaui lelei mo le tele o gaioiga, e pei o le fuaina o faʻamatalaga o le vevela o le vevela vevela poʻo faʻamatalaga eletise, le suʻega o le vevela o le faʻavasegaina o ogaumu poʻo le taele, ma le mauaina o faailo o le vevela ma le pueina o le tele o auala.
Faʻatasi ai ma le fua faʻatatau e sili atu nai lo le 7 1/2, faʻatusatusa i le lautele maualuga-saʻo numera numera tele, lea na faʻaaogaina lautele i le vevela metrology mo se taimi umi, o loʻo i ai le tele o mamanu sili ona lelei i tulaga o le lautele, galuega, saʻo, ma le faigofie o le faʻaogaina e faʻaogaina ai le faʻavasegaina o le vevela e sili atu le saʻo, faigofie ma vave.
Vaega
Fua maaleale o le 10nV / 10μΩ
O le mamanu faʻasolosolo o le ultra-low leo faʻapipiʻi ma le faʻaogaina o le eletise maualalo e faʻaitiitia ai le leo faitau o le faʻailoga faailo, ma faʻateleina ai le faitau faitau i le 10nV / 10uΩ, ma faʻaleleia lelei numera faʻaalia i le taimi o le fuaina o le vevela.
Tulaga lelei faaletausaga
PR291/PR293 faasologa thermometers, faʻaaogaina le fua faatatau fua faʻatatau ma faʻatasi ai ma faʻamaufaʻailoga-tulaga tulaga faʻataʻitaʻiga tetee, e matua maualalo le vevela coefficient ma lelei le mautu faaletausaga.A aunoa ma le faʻaaogaina o le faʻaogaina o le vevela tumau, o le mautu faʻaletausaga o le faasologa atoa e mafai lava ona sili atu le lelei nai lo le faʻaaogaina masani 7 1/2 numera numera.
Tu'ufa'atasia tele-auala maualalo le pisa scanner
I le faaopoopo atu i le laina pito i luma, o loʻo i ai 2 poʻo 5 seti tutoʻatasi o faʻataʻitaʻiga suʻega atoatoa o loʻo tuʻufaʻatasia i luga o le pito i tua e tusa ai ma faʻataʻitaʻiga eseese i le PR291 / PR293 series thermometers.E mafai ona tuto'atasi auala ta'itasi le ituaiga fa'ailoga o le su'ega, ma e maualuga tele le fa'atasi i le va o alalaupapa, o lea e mafai ai ona fa'atinoina le mauaina o fa'amaumauga e tele-auala e aunoa ma ni suiga i fafo.E le gata i lea, o le mamanu maualalo o le pisapisao e mautinoa ai o faailo e fesoʻotaʻi atu i ala o le a le aumaia ai se pisa faitau faaopoopo.
Taui maualuga CJ
O le mautu ma le saʻo o le vevela CJ e taua tele i le fuaina o thermocouples maualuga.E mana'omia le tu'ufa'atasia o mita fa'akomepiuta e masani ona fa'aoga ma mea fa'apitoa tau taui CJ mo le fuaina o le thermocouple.O lo'o tu'ufa'atasia le fa'atonuga maualuga maualuga o le CJ i le PR293 series thermometers, o le mea lea e mafai ai ona iloa le sese CJ o le auala fa'aoga e sili atu nai lo le 0.15 ℃ e aunoa ma isi fa'aoga.
O galuega tau su'esu'ega o le vevela
PR291/PR293 faasologa thermometers o se meafaigaluega suʻega faʻapitoa faʻatulagaina mo le alamanuia metrology vevela.E tolu auala galue o le mauaina, suʻesuʻeina o le tasi-auala, ma le fuaina o le eseesega o le vevela, lea e mafai ai e le fuaina o le eseesega o le vevela ona faʻavasega le tutusa o le vevela o ituaiga uma o masini vevela faifai pea.
Pe a faatusatusa i le multimeter numera masani, o se laina 30mV faapitoa mo le fuaina o S-ituaiga thermocouple ma se laina 400Ω mo PT100 platinum teteʻe fua ua faaopoopo.Ma faʻatasi ai ma polokalame faʻaliliuina mo suʻesuʻega vevela eseese, e mafai ona lagolagoina le tele o masini (e pei o thermocouples masani, thermometers teteʻe o le platinum, thermometers teteʻe a le fale gaosimea ma thermocouple galue) e mafai ona lagolagoina, ma faʻamaumauga faʻamaonia poʻo faʻamaumauga faʻasaʻo e mafai ona faʻasino e suʻe. le vevela o fa'ai'uga o su'ega.
Galuega su'esu'e fa'amaumauga
I le faʻaopoopoga i faʻamatalaga eseese o suʻega, e mafai ona faʻaalia pupuni ma le teuina o faʻamatalaga, faʻamatalaga taimi-maualuga maualuga / laʻititi / averesi tau, e mafai ona faʻatusatusaina le tele o faʻamaumauga mautu o le vevela, ma le maualuga ma le maualalo o faʻamaumauga e mafai ona makaina e faʻafaigofie ai suʻesuʻega faʻamatalaga intuitive. i luga ole nofoaga ole su'ega.
Fuafuaga feaveai
O mita numera sa'o maualuga e masani ona fa'aogaina i fale su'esu'e e masani ona lapopoa ma e le feavea'i.I se faʻatusatusaga, PR291 / PR293 series thermometers e laʻititi i le voluma ma le mamafa, lea e faigofie mo suʻega o le vevela maualuga i le tele o siosiomaga i luga ole laiga.E le gata i lea, o le mamanu o le fausia i totonu o le tele o le maa lithium e faafaigofieina ai foi le faagasologa o galuega.
