1.PT100 na'urori masu auna zafin jikiyawanci ana amfani da su tare da kayan aikin nuni, kayan rikodi, lissafin lantarki, da dai sauransu kai tsaye auna yawan zafin jiki na ruwa, tururi da gas matsakaici da kuma m surface a cikin kewayon -200 ° C ~ 500 ° C a daban-daban samar matakai.Don tantance ko yana da kyau ko mara kyau, kawai yi amfani da multimeter na dijital don auna shi.
2. Halin na'urar firikwensin zafin jiki na PT100 shine cewa tashoshin fitarwa guda biyu (wani lokacin multi-terminal) ana haɗa su tare da multimeter (ko da yake akwai ƙimar juriya).Idan bude da'irar zai zama mara kyau, babu shakka shine mataki na farko a cikin ainihin hukunci.An kayyade ƙimar juriya na juriya na thermal.Misali, yawan zafin jiki na PT100 yana kusa da 110 ohms, kuma yawan zafin jiki na CU50 yana kusa da 55 ohms.Fitar da thermocouple shine ƙimar ƙarfin lantarki.A wani zafin jiki, zai fitar da siginar ƙarfin lantarki na gabaɗaya ƴan zuwa dubun millivolts, wanda za'a iya auna shi da fayil ɗin ƙarfin lantarki na multimeter.
3. Ƙarfin wutar lantarki na thermocouple shine kawai 'yan mV, dangane da daidaito na multimeter.Ana iya amfani da multimeter na dijital don aunawa da yanke hukunci.Fitar da thermocouple yana cikin tsari na millivolts.Ba zai yiwu a gano fitowar sa tare da multimeter ba, amma ana iya auna shi don ci gaba da shi.A mafi yawan lokuta, idan dai an haɗa sashin galvanic (inda aka haɗa wayoyi biyu) to babu iskar oxygenation, babu lalacewa, kuma gabaɗaya babu matsala.Don haka a lokaci guda, ana iya fitar da shi daga kube don dubawa na gani.Don bincika da gaske, ya zama dole a yi amfani da ma'aunin thermocouple don kwatantawa da auna ƙimar millivolt da yake fitarwa.
4. Abin da ke sama shine hanyar gano koPT100 zafin jikisamfur ne na al'ada.Ina fatan in taimaki kowa.Idan kuna da wasu tambayoyi, zaku iya tuntuɓar ma'aikatan fasahar mu.
