Mefuta e Mehlano e Tloaelehileng ka ho Fetisisa ea Li-Sensors tsa Mocheso

-Thermistor

Thermistor ke sesebelisoa sa ho lemoha mocheso oo ho hanyetsa ha oona e leng mosebetsi oa mocheso oa oona. Ho na le mefuta e 'meli ea li-thermistor: PTC (Positive Temperature Coefficient) le NTC (Negative Temperature Coefficient). Ho hanyetsa mocheso oa PTC ho eketseha ka mocheso. Ka lehlakoreng le leng, ho hanyetsa ha li-thermistor tsa NTC ho fokotseha ka mocheso o ntseng o eketseha, 'me mofuta ona oa thermistor o bonahala e le oona o sebelisoang ka ho fetisisa.

-Thermocouple

Hangata li-thermocouples li sebelisoa ho lekanya mocheso o phahameng le mefuta e mengata ea mocheso. Li-Thermocouples li sebetsa ka molao-motheo oa hore mokhanni ofe kapa ofe ea tlas'a mocheso oa mocheso o hlahisa motlakase o monyenyane, e leng ntho e tsejoang e le Seebeck effect. Boholo ba motlakase o hlahisoang bo itšetlehile ka mofuta oa tšepe. Ho na le mefuta e mengata ea li-thermocouples ho itšetlehile ka thepa ea tšepe e sebelisoang. Har'a bona, metsoako ea alloy e se e tumme. Mefuta e fapaneng ea metsoako ea tšepe e teng bakeng sa lits'ebetso tse fapaneng, 'me basebelisi hangata ba e khetha ho latela mocheso o lakatsehang le kutloisiso.

-Mohloli oa mocheso o hanyetsanang le mocheso (RTD)

Lisebelisoa tsa ho hanyetsa mocheso, tse tsejoang hape e le li-thermometer tsa ho hanyetsa. Li-RTD li tšoana le li-thermistors ka hore khanyetso ea tsona e fetoha le mocheso. Leha ho le joalo, ho e-na le ho sebelisa thepa e khethehileng e utloang ho fetoha ha thempereichara joaloka thermitor, li-RTD li sebelisa likhoele tse pota-potileng terata ea motheo e entsoeng ka ceramic kapa khalase. RTD terata ke thepa e hloekileng, hangata platinum, nickel kapa koporo, 'me thepa ena e na le kamano e nepahetseng ea ho hanyetsa-mocheso e sebelisetsoang ho fumana mocheso o lekantsoeng.　

-Themometer ea analoji IC

Mokhoa o mong oa ho sebelisa li-thermistors le li-resistors tsa boleng bo tsitsitseng ka har'a potoloho ea voltage divider ke ho etsisa sensor ea mocheso o tlase oa voltage. Ho fapana le li-thermistor, li-IC tsa analog li fana ka matla a motlakase a batlang a lekana.

-Themometer ea dijithale IC

Lisebelisoa tsa mocheso oa digital li rarahane haholoanyane, empa li ka nepahala haholo. Hape, li ka nolofatsa moralo ka kakaretso hobane phetoho ea analog-to-digital e etsahala ka hare ho thermometer IC ho e-na le sesebelisoa se arohaneng se kang microcontroller. Hape, li-IC tse ling tsa dijithale li ka hlophisoa ho kotula matla ho tsoa methapong ea bona ea data, ho lumella likhokahano ho sebelisa lithapo tse peli feela (ke hore data/matla le fatše).
