0.01~12mm K rudzi rwethermocouple waya yechromel alumel KP KN

Tsananguro pfupi:

Thermocouple yeTankii NiCr-Ni(Type K) ndiyo inonyanya kushandiswa mu thermocouple yese yebasemetal, patembiricha iri pamusoro pe500 °C.
Type K thermocouple ine simba guru rekudzivirira oxidation kupfuura mamwe ma base metal thermocouples. Ine EMF yakakwira inopesana nePlatinum 67, ine kunyatsorurama kwekupisa, kunzwa uye kugadzikana, uye inodhura zvishoma. Inokurudzirwa pa oxidizing kana inert atmospheres, asi haigone kushandiswa zvakananga mumamiriro ezvinhu anotevera:
(1) Neimwe nzira, mhepo inooxidation uye inoderedza kupisa.
(2) Mhepo ine magasi esulfure.
(3) Nguva yakareba isina chinhu.
(4) Mhepo isina kuoxidative yakawanda yakaita sehydrogen necarbon monoxide.

Kushandiswa kwewaya yeThermocouple:
1. Kudziisa - Zvitofu zvegasi zveovheni
2. Kutonhodza - Mafiriji
3. Dziviriro yeinjini - Tembiricha uye tembiricha pamusoro
4. Kudzora tembiricha yepamusoro - Kukanda simbi
