I-LEAT-4 I-Thermal Conductivity Measurement Apparatus

Incazelo emfushane:

Kunezindlela ezimbili zokulinganisa ukuguquguquka kwe-thermal- indlela yesimo sokuqina kanye nendlela eguquguqukayo, leli thuluzi liwuhlobo lwendlela yesimo esiqinile.
Endleleni yesimo sokuqina, sishisisa isampula kuqala, futhi umehluko wezinga lokushisa ngaphakathi kwesampula wenza ukudluliswa kokushisa kusuka kuzinga lokushisa eliphezulu kuya kuzinga lokushisa eliphansi, futhi izinga lokushisa lephoyinti ngalinye ngaphakathi kwesampula lizoshintsha ngesivinini sokushisa kanye nesivinini sokudlulisa ukushisa. ;lapho izimo zokuhlola kanye nemingcele zilawulwa kahle ukwenza inqubo yokushisa nokushisa ifinyelele esimweni sokulinganisa, ukusatshalaliswa kwezinga lokushisa okuzinzile kungenziwa ngaphakathi kwesampula I-conductivity eshisayo ingabalwa kusukela ekusabalaliseni izinga lokushisa.

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Izici zobuchwepheshe eziyinhloko:
1. Isebenzisa ukufudumeza okukodwa kwe-low-voltage, okuphephile futhi kulula ukuyisebenzisa;
2. Ukusebenzisa i-thermocouple ejwayelekile kazwelonke ukukala izinga lokushisa kanye ne-Teflon flexible protection tube, i-thermocouple akulula ukuphuka;
3. Amandla we-thermoelectric akalwa ukumelana okuphezulu kwangaphakathi, ukunemba okuphezulu, isikhulisi se-drift esiphansi kanye ne-voltmeter yedijithali emithathu nengxenye;
4. Ukushisa kokulawula izinga lokushisa kwe-PID kusetshenziselwa ukuzinzisa izinga lokushisa lepuleti lethusi lokushisisa nokuthuthukisa ukunemba kokuhlolwa.

Imingcele yezobuchwepheshe eyinhloko:
1. I-voltmeter yedijithali: Isibonisi esingu-3.5 bit, ububanzi obungu-0 ~ 20mV, ukunemba kwesilinganiso: 0.1% + amagama angu-2;
2. Isitophuwashi sedijithali: Isitophuwashi esinamadijithi angu-5 esinokulungiswa okuncane okungu-0.01s;
3. Uhla lokulawula izinga lokushisa kwesilawuli sokushisa: izinga lokushisa legumbi ~ 120 ℃;
4. I-voltage yokushisa: i-ac36v ephezulu, i-ac25v yokugcina ephansi, amandla okushisa mayelana ne-100W;
5. Ipuleti yethusi yokushisa ukushisa: i-radius 65mm, ukujiya okungu-7mm, isisindo esingu-810g;
6. Izinto zokuhlola: i-duralumin, irabha ye-silicone, ibhodi lerabha, umoya, njll.
7. Isifunda sesinxephezelo sephuzu lokuqandisa le-thermocouple singangezwa ukuze kugcinwe inkinga yokusebenzisa ingxube yamanzi eqhwa;
8. Ezinye izinzwa zokushisa zingasetshenziswa ukukala izinga lokushisa, njenge-PT100, AD590, njll.
