Tus mob ua haujlwm suav nrog sov sov coefficient (PTC) thiab qhov kub thiab txias coefficient (NTC) cov cua nab (thiab kub kub sov kub (CTRS).
1.PtC Tus Khaub Ncaws
Cov ntsuas kub zoo (PTC) yog cov thermistor qhov tshwm sim lossis cov khoom siv uas muaj cov coefficient zoo thiab nce siab ntxiv ntawm ib qho kub. Nws tuaj yeem siv ua qhov ntsuas kub tsis tu ncua. Cov khoom siv yog ib lub cev sintered nrog batio3, srtio3 lossis pbtio3 raws li cov mn, thiab kuj tseem ntxiv cov kev tiv thaiv kab mob ox, thiab kuj tseem ntxiv cov coefficient kub thiab lwm yam ntxiv uas ua si lwm lub luag haujlwm. Cov khoom siv yog tsim los ntawm cov txheej txheem ceramic thiab sintered ntawm qhov kub kom ua platinum titanate thiab nws cov tshuaj sadi-conductive. Yog li cov khoom siv sov sov nrog cov yam ntxwv zoo tau txais. Qhov ntsuas kub coefficient thiab curie taw tes kub sib txawv nrog cov muaj pes tsawg leeg thiab sintering tej yam kev mob (tshwj xeeb yog qhov txias txias).
PTC thermistor tau tshwm sim hauv xyoo pua 20, PTC thermistor tuaj yeem siv rau kev ntsuas kub thiab kev tswj hwm ntawm ib feem ntawm lub tsheb, xws li tswj hwm tus Lub taub dej Instant rhaub dej kub, cua txias thiab txias cia khoom kub, kev siv nws tus kheej cua sov rau roj tsom thiab anemometer thiab lwm yam.
PCT thermistor muaj cov nuj nqi ntawm khaws qhov kub nyob rau hauv ib qho ntau, thiab kuj ua lub luag haujlwm ntawm kev hloov. Siv cov qhov kub tsis kam ua tus yam ntxwv raws li cov cua sov, nws tuaj yeem ua lub luag haujlwm ntawm overheating tiv thaiv rau cov khoom siv hluav taws xob.
2.tc thermistor
Cov ntsuas kub tsis zoo (NTC) yog hais txog cov cua nab kuab thiab cov khoom siv uas muaj qhov tsis zoo raws li qhov kub thiab txias txo qis. The material is a semiconducting ceramic made of two or more metal oxides such as manganese, copper, silicon, cobalt, iron, nickel, and zinc, which are fully mixed, formed, and sintered to produce a thermistor with a negative temperature coefficient (NTC ).
Txoj kev txhim kho theem ntawm NTC thermistor: los ntawm nws qhov kev tshawb pom nyob rau xyoo 19th rau nws txoj kev loj hlob hauv 20th caug xyoo, nws tseem yog tus zoo meej.
Qhov precision ntawm tus pas ntsuas kub sov ntawm tus pas ntsuas kub tuaj yeem ncav cuag 0. 1 ℃, thiab lub sijhawm kub thiab kub tau tsawg dua 10s. Nws tsis yog tsuas yog haum rau tus ntsuas kub grand, tab sis kuj tuaj yeem siv hauv cov khoom noj khoom haus, tshuaj ua noj ua haus thiab kev noj qab haus huv, qhov ntsuas kub siab, kub siab.
3.Ctr Holdistor
Qhov kub tseem ceeb ntsuas cua CTR (tseem ceeb heev tiv thaiv cov xeeb ceem, ntawm qhov kub tsis zoo nrog qhov nce thiab muaj qhov kub thiab txias ua kom sov. Cov khoom muaj pes tsawg leeg yog vanadium, barium, posphorus thiab lwm cov ntsiab lus ntawm cov sib xyaw ua ke, tseem hu ua CTR rau iav coverials. CTR tuaj yeem siv ntau li ntsuas kub thiab lwm yam kev siv.
Tus thermistor tseem tuaj yeem siv los ua hluav taws xob Circuit hauv kev ua twj circuit coculle qhov kev them nyiaj rov qab thiab ntsuas qhov ntsuas ntawm thermocouple txias kawg. Tsis siv neeg nce tswj tau tseeb los ntawm kev siv tus kheej cua kub ntawm NTC thermistor Circuitor, ncua kev sib tw Circuit Court thiab kev tiv thaiv Circuit Court ntawm RC Oscillator tuaj yeem tsim. Siv hluav taws xob PTC yog siv hluav taws xob hluav taws xob ua rau muaj kev tiv thaiv, ntsuas kub, lub sijhawm qeeb, kev them nyiaj kub thiab ntsuas kub, thiab lwm yam.
