-I-Thermistor
I-thermistor iyidivayisi ezwa izinga lokushisa lapho ukumelana kwayo kuwumsebenzi wezinga layo lokushisa.Kunezinhlobo ezimbili zama-thermistors: i-PTC (I-Positive Temperature Coefficient) ne-NTC (I-Negative Temperature Coefficient).Ukumelana ne-PTC thermistor kukhuphuka ngezinga lokushisa.Ngokuphambene, ukumelana kwama-thermistor e-NTC kuncipha ngokukhuphuka kwezinga lokushisa, futhi lolu hlobo lwe-thermistor lubonakala luyi-thermistor esetshenziswa kakhulu.
-Thermocouple
Ama-thermocouples avame ukusetshenziselwa ukukala amazinga okushisa aphezulu kanye nebanga lokushisa elikhudlwana.Ama-Thermocouples asebenza ngesimiso sokuthi noma yimuphi umqhubi ongaphansi kwe-gradient eshisayo ukhiqiza i-voltage encane, into eyaziwa ngokuthi umphumela we-Seebeck.Ubukhulu be-voltage ekhiqizwayo buncike ohlotsheni lwensimbi.Kunezinhlobo eziningi zama-thermocouples kuye ngokuthi insimbi esetshenziswayo.Phakathi kwazo, izinhlanganisela ze-alloy sezidumile.Izinhlobo ezihlukene zezinhlanganisela zensimbi ziyatholakala ezinhlelweni zokusebenza ezihlukene, futhi abasebenzisi ngokuvamile bazikhetha ngokusekelwe ebangeni lokushisa elifunekayo nokuzwela.
-Isitholi sezinga lokushisa elingamelani (RTD)
Izitholi zokushisa ezimelana nazo, ezaziwa nangokuthi ama-resistance thermometers.Ama-RTD afana nama-thermistors ngokuthi ukumelana kwawo kushintsha nezinga lokushisa.Kodwa-ke, esikhundleni sokusebenzisa izinto ezikhethekile ezizwelayo ekushintsheni kwezinga lokushisa njengama-thermistors, ama-RTD asebenzisa amakhoyili aboshwe entanjeni ewumgogodla eyenziwe nge-ceramic noma ingilazi.Intambo ye-RTD iwumsebenzi omsulwa, ngokuvamile iplatinum, i-nickel noma ithusi, futhi le nto inobudlelwano obunembile bokumelana nezinga lokushisa obusetshenziselwa ukunquma izinga lokushisa elilinganisiwe.
-I-analogue thermometer IC
Enye indlela yokusebenzisa ama-thermistors kanye ne-fixed value resistors kusekethe ye-voltage divider iwukulingisa inzwa yokushisa kagesi ephansi.Ngokuphambene nama-thermistors, ama-analog IC ahlinzeka ngogesi ocishe ulingane nomugqa wokukhiphayo.
-I-thermometer yedijithali IC
Imishini yokushisa yedijithali iyinkimbinkimbi kakhulu, kodwa ingaba nembe kakhulu.Futhi, bangenza idizayini ibe lula ngoba ukuguqulwa kwe-analog-to-digital kwenzeka ngaphakathi kwe-thermometer IC kunedivayisi ehlukile njengesilawuli esincane.Futhi, amanye ama-IC edijithali angalungiswa ukuze avune amandla emigqeni yawo yedatha, okuvumela ukuxhumana kusetshenziswa izintambo ezimbili kuphela (okungukuthi idatha/amandla nomhlaba).
