Mai suna Hygrometer?

Takaitaccen

Hygrometer yana amfani da ita don bincike tsarin juyin kasa a cikin yankin, inda "juyin" na nufin kashi mai zafi a cikin gas. Hygrometers sun yi aiki a harkokin da abubuwa masu inganci suka shafi idan an yi lafiya, wanda ya ba su karfin bincike.

Juyin yana da nau'o'i bi:

• Juyin Mai Tsari: Yana nuna kashi mai zafi a kan fadada kasa.

• Juyin Mai Duka: Yana nuna tushen tasiri mai zafi da duka tsari a kan mutum da take da shi a lokacin da yake da temperature, wanda yake iya canza saboda temperature.

Nau'o'in Hygrometer

Hygrometers suna nemanar da nau'o'in kai a kan bayyana juyin, sama da:

Resistive Hygrometer

Resistive hygrometer yana da film mai gudummawa na karamin abubuwa kamar lithium chloride ko carbon, wanda ana jiye a kan elektrodun kasa. Tasirin film din yana canza idan an yi lafiya a kan juyin kasa.

Kashi mai zafi wanda lithium chloride ke samu yana nuna kan juyin mai duka. Juyin mai duka mafi yawa yana ba lithium chloride a samu kashi mai zafi mafi yawa, wanda yake basu tasirin film din.

Canzan tasirin yana daidaita ta amfani da karamin current mai tsari (AC) a bridge circuit. Karamin current mai tsari (DC) ana koyarwa, saboda zai iya yan kawo film din na lithium chloride. Zama ta karamin current yana nuna tasirin, wanda yake nuna juyin mai duka.

Capacitive Hygrometer

Capacitive hygrometer yana bincika juyin kasa ta hanyar canzan capacitance na capacitor, wanda yana ba da taurari mai kyau. Yana da material mai sauya (wanda yana da yawan samun ruwan) a kan elektrodun kasa. Samun ruwan da material din yana canza capacitance na capacitor, wanda yana tabbatar da electronic circuit.

Microwave Refractometer

Microwave refractometer yana bincika refractive index na kasa mai juyin a lokacin da juyin yana canza. Refractive index - yana nuna tushen tasiri mai tsari a kan medium na musamman - yana daidaita ta amfani da dielectric constant (ta hanyar capacitor) ko frequency shifts a kasa mai juyin.

Aluminium Oxide Hygrometer

Wannan hygrometer yana amfani da aluminium mai anodized da aluminium oxide. Juyin yana canza dielectric constant da tasirin aluminium. Yana amfani da aluminium a kan elektrode na farko da gold layer a kan elektrode na biyu.

Elektrode na biyu yana da porous don samun air-vapour mixtures. Juyin yana canza capacitance da tasirin material, wanda yake canza impedance. Wannan impedance yana daidaita ta amfani da bridge circuit, wanda yana ba wannan hygrometer a kan muhimmin component a electronic systems.

Crystal Hygrometer

Tambayar ta haka yana nuna crystal hygrometer ta hanyar quartz.

A cikin crystal hygrometer, yana amfani da hygroscopic crystal ko crystal mai an rubuta hygroscopic material. Idan crystal yana samu kashi mai ruwa, massashin yake yana canza. Canzan mass yana nuna kan kashi mai ruwa da crystal ke samu.
