Yadda za a bambanta samfurin thermocouple

Za a iya raba thermocouples da aka saba amfani da su zuwa kashi biyu: daidaitattun ma'aunin zafi da sanyio da kuma ma'aunin ma'aunin zafi da sanyio. Ma'aunin thermocouple da ake kira ma'aunin thermocouple yana nufin ma'aunin thermocouple wanda ikon thermoelectric da zafinsa ke ƙayyadaddun ƙa'idar ƙasa, wanda ke ba da damar kurakurai, kuma yana da daidaitaccen tebur mai ƙididdigewa. Yana da madaidaicin bayyanar nuni don zaɓi. Ma'aunin ma'aunin zafi da sanyio ba su da kyau kamar daidaitattun ma'aunin zafi da sanyio dangane da kewayon aikace-aikace ko tsari na girma. Gabaɗaya, babu daidaitaccen tebur mai ƙididdigewa, kuma ana amfani da su galibi don aunawa a wasu lokuta na musamman.

Madaidaitan ma'aunin ma'aunin zafi da sanyio, S, B, E, K, R, J, da T, ma'aunin zafi da sanyioyi ne na daidaitaccen ƙira a China.

Lambobin ƙididdigar thermocouples galibi S, R, B, N, K, E, J, T da sauransu. A halin da ake ciki, S, R, B na cikin ɗanyen murhun ƙarfe mai ƙima, kuma N, K, E, J, T na cikin thermocouple na ƙarfe mai arha.

Mai zuwa shine bayanin lambar fihirisar thermocouple

(S-type thermocouple) platinum rhodium 10-platinum thermocouple
Platinum rhodium 10-platinum thermocouple (S-type thermocouple) wani ma'aunin zafi da sanyio na ƙarfe ne mai daraja. An ƙayyade diamita na waya biyu kamar 0.5mm, kuma kuskuren da aka yarda shine -0.015mm. Haɗin sinadarai na ƙima na tabbataccen lantarki (SP) shine gawa na platinum-rhodium tare da 10% rhodium, 90% platinum, da platinum mai tsabta don ƙarancin lantarki (SN). Akafi sani da single platinum rhodium thermocouple. Matsakaicin zafin aiki na dogon lokaci na wannan thermocouple shine 1300℃, kuma matsakaicin matsakaicin matsakaicin lokacin aiki shine 1600℃.
