-Thermistor
Thermistor ndi chipangizo chozindikira kutentha chomwe kukana kwake ndi ntchito ya kutentha kwake.Pali mitundu iwiri ya zotenthetsera: PTC (Positive Temperature Coefficient) ndi NTC (Negative Temperature Coefficient).Kukana kwa PTC thermistor kumawonjezeka ndi kutentha.Mosiyana ndi izi, kukana kwa ma thermistor a NTC kumachepa ndi kutentha kowonjezereka, ndipo mtundu uwu wa thermistor umawoneka ngati wogwiritsidwa ntchito kwambiri.
-Thermocouple
Ma thermocouples nthawi zambiri amagwiritsidwa ntchito kuyeza kutentha kwambiri komanso kutentha kwakukulu.Ma Thermocouples amagwira ntchito pa mfundo yakuti kondakitala aliyense amene ali ndi mphamvu yotentha amatulutsa magetsi ang'onoang'ono, chodabwitsa chotchedwa Seebeck effect.Kukula kwa magetsi opangidwa kumadalira mtundu wachitsulo.Pali mitundu yambiri ya ma thermocouples malingana ndi zitsulo zomwe zimagwiritsidwa ntchito.Pakati pawo, kuphatikiza kwa aloyi kwatchuka.Mitundu yosiyanasiyana yophatikizira zitsulo imapezeka pazogwiritsa ntchito zosiyanasiyana, ndipo ogwiritsa ntchito nthawi zambiri amasankha kutengera kutentha komwe akufuna komanso kumva.
-Chojambulira kutentha kwa Resistance (RTD)
Zowunikira kutentha kwa Resistance, zomwe zimadziwikanso kuti resistance thermometers.Ma RTD ndi ofanana ndi ma thermistors chifukwa kukana kwawo kumasintha ndi kutentha.Komabe, m'malo mogwiritsa ntchito zida zapadera zomwe zimakhudzidwa ndi kusintha kwa kutentha monga zotenthetsera, ma RTD amagwiritsa ntchito mazenera ozungulira pamawaya opangidwa ndi ceramic kapena galasi.Waya wa RTD ndi chinthu choyera, nthawi zambiri platinamu, faifi tambala kapena mkuwa, ndipo zinthuzi zimakhala ndi ubale weniweni wa kukana kutentha womwe umagwiritsidwa ntchito kudziwa kutentha kwake.
-Analogi thermometer IC
Njira ina yogwiritsira ntchito ma thermistors ndi ma fixed value resistors mu gawo la voliyumu yamagetsi ndikutsanzira sensor yotsika yamagetsi.Mosiyana ndi ma thermistors, ma analogi a IC amapereka mphamvu yotulutsa pafupifupi mzere.
-Digital thermometer IC
Zida za kutentha kwa digito zimakhala zovuta kwambiri, koma zikhoza kukhala zolondola kwambiri.Komanso, amatha kuphweka kapangidwe kake chifukwa kutembenuka kwa analogi kupita ku digito kumachitika mkati mwa thermometer IC m'malo mwa chipangizo chosiyana monga chowongolera chaching'ono.Komanso, ma IC ena a digito amatha kusinthidwa kuti akolole mphamvu kuchokera ku mizere yawo ya data, kulola kulumikizana pogwiritsa ntchito mawaya awiri okha (ie data/mphamvu ndi nthaka).
