Isisetshenziswa Sokulinganisa Ukushisa kwe-LEAT-4 Isithombe Esifakiwe

Imishini Yokulinganisa Ukushisa kwe-LEAT-4

Incazelo emfushane:

Kunezindlela ezimbili zokulinganisa ukuhanjiswa kokushisa - indlela yesimo esizinzile kanye nendlela eguquguqukayo, leli thuluzi liwuhlobo lwendlela yesimo esizinzile.
Ngendlela yesimo esizinzile, sifudumeza isampula kuqala, futhi umehluko wokushisa ngaphakathi kwesampula wenza ukudluliselwa kokushisa kusuka ekushiseni okuphezulu kuya ekushiseni okuphansi, futhi izinga lokushisa lephuzu ngalinye ngaphakathi kwesampula lizoshintsha ngesivinini sokushisa kanye nesivinini sokudlulisa ukushisa; lapho izimo zokuhlola kanye namapharamitha kulawulwa kahle ukwenza inqubo yokushisa kanye nokudlulisa ukushisa ifinyelele esimweni sokulingana, ukusabalalisa izinga lokushisa okuzinzile kungakhiwa ngaphakathi kwesampula. Ukuhanjiswa kokushisa kungabalwa kusukela ekusakazweni kwezinga lokushisa.

Amathegi Omkhiqizo

Izici zobuchwepheshe eziyinhloko:
1. Isebenzisa ukushisa okuhlukile okune-voltage ephansi, okuphephile futhi okulula ukukusebenzisa;
2. Ukusebenzisa i-thermocouple ejwayelekile kazwelonke ukukala izinga lokushisa kanye ne-Teflon flexible protection tube, i-thermocouple akulula ukuyiphula;
3. Amandla okushisa kagesi alinganiswa ngokumelana okuphezulu kwangaphakathi, ukunemba okuphezulu, i-amplifier ephansi yokukhukhuleka kanye ne-voltmeter yedijithali emithathu nengxenye;
4. Ukushisa kokulawula izinga lokushisa kwe-PID kusetshenziselwa ukuzinzisa izinga lokushisa kwepuleti lethusi elifudumezayo nokuthuthukisa ukunemba kokuhlolwa.

Amapharamitha obuchwepheshe ayinhloko:
1. I-voltmeter yedijithali: isibonisi sama-bit angu-3.5, ububanzi obungu-0 ~ 20mV, ukunemba kokulinganisa: 0.1% + amagama angu-2;
2. Iwashi lokumisa ledijithali: Iwashi lokumisa elinezinombolo ezi-5 elinesinqumo esincane esingu-0.01s;
3. Ububanzi bokulawula izinga lokushisa lomlawuli wokushisa: izinga lokushisa legumbi ~ 120 ℃;
4. I-voltage yokushisa: i-ac36v ephezulu, i-ac25v ephansi, amandla okushisa angaba ngu-100W;
5. Ipuleti lethusi lokushabalalisa ukushisa: irediyasi engu-65mm, ukujiya okungu-7mm, isisindo esingu-810g;
6. Izinto zokuhlola: i-duralumin, irabha ye-silicone, ibhodi yerabha, umoya, njll.
7. Isekethe yesinxephezelo sendawo yokuqandisa ye-thermocouple ingangezwa ukuze kuncishiswe inkinga yokusebenzisa ingxube yamanzi eqhwa;
8. Ezinye izinzwa zokushisa zingasetshenziswa ukukala izinga lokushisa, njenge-PT100, AD590, njll.
