PR293 Series Nanovolt Microhm Thermometer
Kugadziriswa kwakanyatsojeka kwe7 1/2
Yakabatanidzwa thermocouple CJ compensator
Nzira dzakawanda dzekuyera
Mathermometer ePR291 series microhm uye mathermometer ePR293 series nanovolt microhm zvishandiso zvekuyera zvakanyatsonaka zvakagadzirirwa metrology yetembiricha. Zvakakodzera mabasa akawanda, akadai sekuyera data retembiricha re sensor yetembiricha kana data remagetsi, bvunzo yekuenzana kwetembiricha yemaovheni ekugadzirisa kana emabhati, uye kutora chiratidzo chetembiricha nekurekodha nzira dzakasiyana-siyana.
Nekukwanisa kwayo kuyera zviri nani pane 7 1/2, zvichienzaniswa nedhijitari ine ma multimeters akanyatsogadzirwa, ayo ave achishandiswa zvakanyanya mukuongorora tembiricha kwenguva yakareba, kune magadzirirwo akawanda akagadziridzwa maererano nehukuru, mashandiro, kururama, uye nyore kushandisa kuti maitiro ekuenzanisa tembiricha ave akarurama, ari nyore uye nekukurumidza.
Zvinhu zvirimo
Kuyerwa kwekunzwisiswa kwe10nV / 10μΩ
Dhizaini yekubudirira kwe amplifier yeruzha yakaderera zvakanyanya uye module yesimba remagetsi rinoyerera zvishoma nezvishoma inoderedza zvakanyanya ruzha rwekuverenga kwechiratidzo, nokudaro ichiwedzera kunzwa kwekuverenga kusvika ku10nV/10uΩ, uye ichiwedzera zvinobudirira manhamba ekuratidza anoshanda panguva yekuyerwa kwetembiricha.
Kugadzikana kwegore negore kwakanaka kwazvo
Mathermometer ePR291/PR293 series, achishandisa mutemo wekuyera chiyero uye ane ma reference-level standard resistors akavakirwa mukati, ane tembiricha yakaderera zvakanyanya uye kugadzikana kwakanaka kwegore negore. Pasina kushandisa basa re constant temperature reference, kugadzikana kwegore negore kwese kunogona kuve kuri nani zvakanyanya kupfuura 7 1/2 digital multimeter inowanzoshandiswa.
Yakabatanidzwa multi-channel low-ruzha scanner
Pamusoro pechiteshi chepamberi, kune ma "full-function test terminals" maviri kana mashanu akazvimiririra akabatanidzwa pa "rear panel" zvichienderana nemamodheru akasiyana muPR291/PR293 series thermometers. Chiteshi chega chega chinogona kugadza chega rudzi rwechiratidzo chekuedza, uye chine kuenderana kwakanyanya pakati pema "channels", saka kuwanikwa kwedata re "multi-channel" kunogona kuitwa pasina switch dzekunze. Pamusoro pezvo, dhizaini yeruzha rwakaderera inoita kuti masaini akabatana nema "channels" asaunze ruzha rwekuverenga rwakawedzerwa.
Muripo weCJ wakanyatsogadzirwa
Kugadzikana uye kururama kwekupisa kweCJ kunoita basa rakakosha pakuyera mathermocouples akanyatsojeka. Mamita edhijitari anonyanya kushandiswa anofanirwa kusanganiswa nemidziyo yakakosha yeCJ yekuyera mathermocouple. Module yeCJ yekubhadharisa yakatsaurirwa High-precision yakabatanidzwa muPR293 series thermometers, saka kukanganisa kweCJ kwechiteshi chakashandiswa kunopfuura 0.15℃ pasina zvimwe zvinhu zvinogona kuitika.
Mabasa ekuenzanisa tembiricha yakawanda
Mathermometer ePR291/PR293 akatevedzana chishandiso chakakosha chekuedza chakagadzirirwa indasitiri yemetrology yekupisa. Kune nzira nhatu dzekushanda dzekuwana, kuteedzera kwechiteshi chimwe chete, uye kuyera musiyano wekupisa, pakati padzo nzira yekuyera musiyano wekupisa inogona kuongorora kufanana kwekupisa kwemarudzi ese emidziyo yekupisa inogara iripo.
Zvichienzaniswa nedhijitari multimeter yechinyakare, huwandu hwe30mV hwakanyanya kuyera maS-type thermocouples uye huwandu hwe400Ω hwekuyera PT100 platinum resistance measurement hunowedzerwa. Uye nemapurogiramu ekushandura akavakirwa mukati emasensa akasiyana-siyana ekupisa, masensa akasiyana-siyana (akadai semastandard thermocouples, standard platinum resistance thermometers, industrial platinum resistance thermometers uye working thermocouples) anogona kutsigirwa, uye data retifiketi kana data rekugadzirisa rinogona kutariswa kuti riongorore tembiricha yemhedzisiro yebvunzo.
Basa rekuongorora data
Pamusoro pedata rekuyedza rakasiyana-siyana, macurve nekuchengetwa kwedata zvinogona kuratidzwa, data renguva chaiyo rakakosha/risingapfuure/avhareji, data rakasiyana-siyana rekugadzikana kwetembiricha rinogona kuverengerwa, uye data repamusoro nerisingapfuure rinogona kumakwa kuti zvive nyore kuongorora data panzvimbo yekuyedza.
Dhizaini inotakurika
Mamita edhijitari anonyanya kushandiswa mumarabhoritari anowanzo kuve akakura uye haatakurwi. Kusiyana neizvi, mathermometer ePR291/PR293 akatevedzana ane huremu hushoma, izvo zviri nyore kuyedza tembiricha yepamusoro munzvimbo dzakasiyana siyana dziri panzvimbo iyi. Pamusoro pezvo, dhizaini yebhatiri re lithium rakakura rakavakirwa mukati inoitawo kuti mashandiro ave nyore.
