Iindidi eziNhlanu eziQhelekileyo zoVavanyo lobushushu

-Thermistor

I-thermistor sisixhobo esivavanya ubushushu esinokumelana nobushushu baso. Kukho iindidi ezimbini zezifudumezi: i-PTC (i-Positive Temperature Coefficient) kunye ne-NTC (i-Negative Temperature Coefficient). Ukumelana ne-PTC thermistor kwandisa ngobushushu. Ngokwahlukileyo koko, ukuxhathisa kwe-NTC thermistors kuncipha ngokunyuka kwamaqondo obushushu, kwaye olu hlobo lwe-thermistor lubonakala luyi-thermistor esetyenziswa kakhulu.

-Thermocouple

IiThermocouples zihlala zisetyenziselwa ukulinganisa amaqondo obushushu aphezulu kunye noluhlu olukhulu lobushushu. I-Thermocouples isebenza kumgaqo wokuba nayiphi na i-conductor ephantsi kwe-thermal gradient ivelisa i-voltage encinci, into eyaziwa ngokuba yi-Seebeck effect. Ubungakanani bombane owenziweyo buxhomekeke kuhlobo lwetsimbi. Kukho iintlobo ezininzi ze-thermocouples ngokuxhomekeke kwizinto zetsimbi ezisetyenzisiweyo. Phakathi kwabo, ukudibanisa i-alloy kuye kwaziwa. Iindidi ezahlukeneyo zendibaniselwano zetsimbi ziyafumaneka kwizicelo ezahlukeneyo, kwaye abasebenzisi badla ngokuzikhetha ngokusekelwe kuluhlu olufunekayo lobushushu kunye novakalelo.

-Isikhangeli sobushushu esichasayo (RTD)

Izixhobo zokujonga ubushushu obunganyangekiyo, ezaziwa ngokuba ziithemometha zokuxhathisa. Ii-RTD ziyafana ne-thermistors kuba ukuchasana kwazo kuyatshintsha ngobushushu. Nangona kunjalo, endaweni yokusebenzisa izinto ezikhethekileyo ezibuthathaka kutshintsho lweqondo lobushushu njengezixhobo zokufudumala, ii-RTD zisebenzisa iikhoyili ezijikelezwe kucingo olungundoqo olwenziwe ngeceramic okanye iglasi. Ucingo lwe-RTD luyinto ecocekileyo, ngokuqhelekileyo iplatinum, i-nickel okanye ubhedu, kwaye le nto inobudlelwane obuchanekileyo bokumelana nobushushu obusetyenziselwa ukumisela ubushushu obulinganisiweyo.　

-Ithemomitha ye-analog IC

Enye indlela yokusebenzisa i-thermistors kunye ne-resistors ixabiso elisisigxina kwi-voltage divider circuit kukulinganisa i-sensor ye-voltage ephantsi yobushushu. Ngokuchaseneyo ne-thermistors, ii-ICs ze-analog zibonelela ngombane ophantse ube ngumgca wokuphuma.

-Ithemometha yedijithali IC

Izixhobo zobushushu bedijithali zinzima ngakumbi, kodwa zinokuchaneka kakhulu. Kwakhona, banokwenza lula ukuyila ngokubanzi kuba ukuguqulwa kwe-analog-to-digital kwenzeka ngaphakathi kwe-thermometer ye-IC kunesixhobo esahlukileyo esinjenge-microcontroller. Kwakhona, ezinye ii-ICs zedijithali zinokumiselwa ukuze zivune amandla kwimigca yazo yedatha, zivumela uqhagamshelo kusetyenziswa iingcingo ezimbini kuphela (oko kukuthi idatha/amandla nomhlaba).
