Indlela yokulinganisa yegesi Thermocouple

Isikhathi sokuphendula esishisayo segesitherkocouplekuyinkimbinkimbi ngokwengeziwe. Izimo ezahlukahlukene zokuhlola zinemiphumela ehlukile yokulinganisa ngoba ithintwa ukushisa kokushisa kwe-thermocouple kanye nendawo ezungezile, futhi isikhathi sokuphendula sokushisa sifushane. Ukuze wenze isikhathi sokuphendula esishisayo somkhiqizo we-thermocouple, amazinga kazwelonke: Isikhathi sokuphendula esishisayo kufanele senziwe kudivayisi ekhethekile yokugeleza kwamanzi. Izinga lokugeleza kwamanzi ledivaysi kufanele ligcinwe ngo-0,4 ± 0.05 m / s, izinga lokushisa lokuqala liku-40-50 ° C. Ngesikhathi sokuhlola, ukuguquka kwamanzi kungafanele kube ngaphezulu kwe- ± 1% ye-excation yokushisa. Ukujula kokujula kwecala i-thermocouple kungu-150 mm noma ukujula okuklanywe (khetha inani elincane futhi kukhombisa embikweni wokuhlola).
Njengoba le divayisi iyinkimbinkimbi ngokwengeziwe, amayunithi ambalwa kuphela anedivayisi enjalo, ngakho-ke ama-National Standard ahlinzeka ukuthi umenzi uvunyelwe ukuxoxisana nabasebenzisi, futhi ezinye izindlela zokuhlola zingasetshenziswa, kepha imininingwane kufanele ikhonjiswe.
Kusukela Thermocouples ku-T-TYPEtherkocouplezingamazinga okushisa asekamelweni, isikhathi sokuphendula esishisayo akulula ukukala, ngakho-ke amazinga kazwelonke angathatha isikhundla sawo se-hermorectriclerclyctriclercyctric esebeni esebenzisa umhlangano we-thermocode we-thermocode ye-s-thermocople ye-s-thermococople efanayo ecacisiwe, bese uvivinya.

Lapho isivivinyo, umphumela we-thermocouple kufanele uqoshwe ngesikhathi u-T0.5 ahambelana nezinyathelo zokushisa nge-50%, uma kunesidingo, angaqopha isikhathi sokuphendula esingu-10% wesikhathi sokuphendula esishisayo T0.9. Isikhathi sokuphendula esishisayo esirekhodiwe kufanele sibe inani elijwayelekile okungenani lemiphumela emithathu yokuhlola. Umphumela ngamunye wokulinganisa kufanele ube ngaphakathi ± 10% wokuphambuka ngokwesilinganiso. Ngaphezu kwalokho, isikhathi esidingekayo ukwakha ushintsho lwesinyathelo sokushisa akufanele sidlule ingxenye eyodwa yeshumi ye-T0.5 ye-thermococle ehloliwe. Ukuqopha isikhathi sokuphendula ithuluzi noma ithuluzi akufanele kudlule ingxenye eyodwa yeshumi ye-T0.5 yecalatherkocouple.
