Isixhobo Sokulinganisa Ubushushu be-LEAT-4 Umfanekiso Ovezweyo

Izixhobo zokulinganisa ubushushu ze-LEAT-4

Inkcazo emfutshane:

Kukho iindlela ezimbini zokulinganisa ukuhanjiswa kobushushu- indlela ye-steady-state kunye nendlela ye-dynamic, esi sixhobo siluhlobo lwendlela ye-steady-state.
Kwindlela ye-steady-state, sifudumeza isampuli kuqala, kwaye umahluko wobushushu ngaphakathi kwesampuli wenza ukudluliselwa kobushushu ukusuka kubushushu obuphezulu ukuya kubushushu obuphantsi, kwaye ubushushu bendawo nganye ngaphakathi kwesampuli buya kutshintsha ngesantya sobushushu kunye nesantya sokudluliselwa kobushushu; xa iimeko zovavanyo kunye neeparameter zilawulwa ngokufanelekileyo ukwenza inkqubo yokudluliselwa kobushushu kunye nobushushu ifikelele kwimeko yokulingana, ukusasazwa kobushushu okuzinzileyo kunokwakheka ngaphakathi kwesampuli. Ukuhanjiswa kobushushu kungabalwa ukusuka kukusasazwa kobushushu.

Iinkcukacha zeMveliso

Iithegi zeMveliso

Iimpawu zobugcisa eziphambili:
1. Isebenzisa ukufudumeza okuzimeleyo okune-voltage ephantsi, okukhuselekileyo nokulula ukuyisebenzisa;
2. Ukusebenzisa i-thermocouple esemgangathweni kazwelonke ukulinganisa ubushushu kunye netyhubhu yokukhusela eguquguqukayo yeTeflon, i-thermocouple ayilula ukuyiqhekeza;
3. Amandla ombane alinganiswa ngokuxhathisa okuphezulu kwangaphakathi, ukuchaneka okuphezulu, i-amplifier yokushukuma okuphantsi kunye ne-voltmeter yedijithali ezintathu nesiqingatha;
4. Ulawulo lobushushu lwe-PID lusetyenziselwa ukuzinzisa ubushushu bepleyiti yobhedu yokufudumeza nokuphucula ukuchaneka kovavanyo.

Iiparameter eziphambili zobugcisa:
1. I-voltmeter yedijithali: Isibonisi seebhithi ezi-3.5, uluhlu oluyi-0 ~ 20mV, ukuchaneka komlinganiselo: 0.1% + amagama ama-2;
2. I-stopwotch yedijithali: I-stopwotch enamanani ama-5 enesisombululo esincinci se-0.01s;
3. Uluhlu lolawulo lobushushu lolawulo lobushushu: ubushushu begumbi ~ 120 ℃;
4. I-voltage yokufudumeza: i-ac36v ephezulu, i-ac25v ephantsi, amandla okufudumeza malunga ne-100W;
5. Ipleyiti yobhedu yokusasaza ubushushu: irediyasi 65mm, ubukhulu 7mm, ubunzima 810g;
6. Izixhobo zovavanyo: i-duralumin, irabha ye-silicone, ibhodi yerabha, umoya, njl.
7. Isekethe yokuhlawula indawo yokukhenkceza ye-thermocouple ingongezwa ukuze kuthintelwe ingxaki yokusebenzisa umxube wamanzi omkhenkce;
8. Ezinye izinzwa zobushushu zingasetyenziselwa ukulinganisa ubushushu, ezifana ne-PT100, AD590, njl.
