Ama-thermistors asetshenziswa kabanzi ekutholeni izinga lokushisa kanye nezicelo zokulawula kuzo zonke izimboni ezahlukene. Phakathi kwezinhlobo ezahlukene zeama-thermistors, i-PTC (Positive Temperature Coefficient) kanye ne-PT100 yizinhlobo ezimbili ezivame ukusetshenziswa. Zombili izinhlobo zama-thermistors zisetshenziselwa ukulinganisa izinga lokushisa, kodwa zinezici nezinhlelo zokusebenza ezahlukene. Ukuqonda umehluko phakathi kwama-thermistors e-PTC kanye ne-PT100 kubalulekile ekukhetheni inzwa efanele izidingo zakho ezithile zokuzwa izinga lokushisa.
I-thermistor ye-PTC:
Ama-thermistors e-PTC angama-resistor azwela izinga lokushisa ane-coefficient enhle yokushisa, okusho ukuthi ukumelana kwawo kuyanda njengoba izinga lokushisa likhuphuka. Lawa ma-thermistors enziwe ngezinto ze-ceramic ezifana ne-barium titanate, futhi ukumelana kwawo kushintsha kakhulu ngokushintsha kwezinga lokushisa. Ama-thermistors e-PTC avame ukusetshenziswa ezinhlelweni ezidinga ukuvikelwa kwezinga lokushisa ngokweqile, ukuzilawula, kanye nokukhawulelwa kwamanje.
Esinye sezici eziyinhloko zama-thermistors e-PTC yizakhiwo zawo ezizilawulayo. Njengoba izinga lokushisa likhuphuka, ukumelana kwe-thermistor ye-PTC kuyanda, okubangela ukuthi ugesi wehle. Lokhu kuziphatha okuzilawulayo kwenza ama-thermistors e-PTC afanelekele izinhlelo zokusebenza ezifana nokuvikela imoto, izinto zokushisa, kanye nokuvikelwa kogesi oweqile kumasekethe kagesi.
Inzwa yokushisa egoqayo:
Izinzwa zokushisa ezigoqekayo zisetshenziswa emishinini kagesi ukuqapha izinga lokushisa lama-winding kuma-motor, ama-transformer kanye neminye imishini kagesi. Lezi zinzwa zibalulekile ekuvimbeleni ukushisa ngokweqile nokuqinisekisa ukusebenza okuphephile kwemishini. Izinzwa zokushisa ezigoqekayo zivame ukusebenzisa ama-thermistors e-PTC njengezinto zokuzwa izinga lokushisa ngoba zinezici ezizilungisayo futhi zizwela kakhulu ekushintsheni kwezinga lokushisa.
I-thermistor ye-PT100:
I-PT100 iyisitholi sokushisa sokumelana (RTD) esisebenzisa iplatinum njengento yokuzwa. Ngokungafani nama-thermistors e-PTC, ukumelana kwama-thermistors e-PT100 kuyanda ngokulandelana nokushisa, kulandela ubudlelwano obujwayelekile bokumelana nokushisa obuchazwe yi-International Electrotechnical Commission (IEC). Ama-thermistors e-PT100 aziwa ngokunemba kwawo okuphezulu, ukuzinza kanye nobubanzi bokulinganisa izinga lokushisa, okwenza afaneleke kakhulu ekusetshenzisweni kokulinganisa izinga lokushisa ngokunemba.
I-thermistor ye-PT100 inokumelana okungu-100 ohms ku-0°C futhi ikhuphuka cishe ngo-0.385 ohms ngesilinganiso ngasinye sokwanda kwezinga lokushisa. Lobu budlelwano obuqondile phakathi kokumelana nezinga lokushisa buvumela ukulinganiswa kwezinga lokushisa okunembile nokuthembekile ebangeni elibanzi lokushisa.
Umehluko phakathi kwe-PTC ne-PT100:
Umehluko omkhulu phakathi kwama-thermistors e-PTC kanye ne-PT100 yizimpawu zawo zokumelana nokushisa. Ama-thermistors e-PTC abonisa ubudlelwano bokumelana nokushisa obungaqondile obune-coefficient yokushisa enhle, kuyilapho ama-thermistors e-PT100 enobudlelwano bokumelana nokushisa obuqondile obune-coefficient yokushisa eseduze ne-zero.
Omunye umehluko ophawulekayo yizinto ezisetshenziswa ekwakhiweni kwayo. Ama-thermistors e-PTC avame ukwenziwa ngezinto zobumba, kuyilapho ama-thermistors e-PT100 esebenzisa i-platinum njengento yokuzwa. Ukusetshenziswa kwe-platinum kuma-thermistors e-PT100 kunegalelo ekuqondeni nasekuzinzeni kwawo okuphezulu, ikakhulukazi ezindaweni zezimboni nezamalebhu ezidinga kakhulu.
isicelo:
Ama-thermistors e-PTC angasetshenziswa ekuvikeleni ukushisa ngokweqile, izinto zokushisa ezizilawulayo, amasekethe akhawulelayo wamanje kanye nokuvikelwa kwezimoto. Ukuziphatha kwawo okuzilawulayo kuwenza afanelekele ukusetshenziswa lapho ukulawulwa kokushisa nokuvikelwa kubalulekile khona.
Ngakolunye uhlangothi, ama-thermistors e-PT100 asetshenziswa kabanzi ezindaweni zezimboni nezamalebhu ukuze kulinganiswe izinga lokushisa ngendlela enembile. Avame ukusetshenziswa ezinhlelweni zokuqapha izinga lokushisa, amakamelo ezemvelo, izinhlelo ze-HVAC, kanye nezinhlelo zocwaningo lwesayensi lapho ukuzwa izinga lokushisa okunembile nokuzinzile kubalulekile khona.
Ngamafuphi, yize ama-thermistors e-PTC kanye ne-PT100 esetshenziselwa ukuzwa izinga lokushisa, anezimpawu kanye nezinhlelo zokusebenza ezahlukene. Ama-thermistors e-PTC aziwa ngokuziphatha kwawo okuzilawula futhi avame ukusetshenziswa ezinhlelweni zokusebenza ezidinga ukuvikelwa kokushisa ngokweqile kanye nokukhawulelwa kwamanje. Ama-thermistors e-PT100, ngakolunye uhlangothi, anikeza ukunemba okuphezulu kanye nokuzinza, okwenza afanelekele ukulinganiswa kwezinga lokushisa okunembile ezindaweni zezimboni kanye nelebhu. Ukuqonda umehluko phakathi kwala ma-thermistors kubalulekile ekukhetheni inzwa efanelekile yezidingo zakho ezithile zokuzwa izinga lokushisa.
