Yakasiyana-siyana Chromel Alumel Bare Wire yeK Type Temperature Sensor

Tsanangudzo Pfupi

Thermocouple inzwa inoshandiswa kuyera tembiricha. Thermocouples inoumbwa nemakumbo maviri ewaya akagadzirwa nesimbi dzakasiyana. Makumbo ewaya anosungirirwa pamwe chete kune imwe mugumo, achigadzira mubatanidzwa. Uku ndiko kunopimwa tembiricha. Kana junction ikasangana nekushanduka kwekushisa, voltage inogadzirwa. Iyo voltage inogona kududzirwa uchishandisa thermocouple reference matafura kuverenga tembiricha.
NiCr-NiAl (Type K) thermocouple waya inowana kushandiswa kwakakura kwazvo mune yese basemetal thermocouple, patembiricha iri pamusoro pe500 °C.

Yakasiyana-siyana Chromel Alumel Bare Wire yeK Type Temperature Sensor

TYPE K (CHROMEL vs ALUMEL) inoshandiswa mukuita oxidizing, inert kana yakaoma kuderedza mamiriro ekunze. Kuratidzwa kune vacuum kunogumira kunguva pfupi. Inofanirwa kuchengetedzwa kubva kune sulfurous uye marginally oxidizing atmospheres. Kuvimbika uye kwakarurama pakupisa kwepamusoro.
