Intee ayuu le'eg yahay kulayliyaha ku jira digsiga qaboojinta?
Waxaa jira noocyo badan oo ah thermistors. Guud ahaan, nooca dhalada-shaaban, nooca epoxy, nooca silig-dhexroor yar-yar, iwm ayaa loo isticmaalaa cabbirka heerkulka. Sida qaybaha cabbiraadda heerkulka ee makiinadaha kicinta, nooca dhalada lagu xidhay iyo qalabyada kale ayaa guud ahaan loo isticmaalaa in lagu sameeyo kulayliyaha. Qaybaha iska caabinta, kulayliyeyaasha heerkulka xun, taas oo ah, kulayliyeyaasha NTC, iska caabinta heerkulka qolka waa qiyaastii 100k, sidoo kale waxaa jira 10K, 50K iyo tilmaamo kale, laakiin 100K ayaa loo isticmaalaa marar badan, qaladku waa inta badan ± 1% ama ± 2 About. %, caabbinta kulayliyaha NTC ayaa hoos u dhacaysa heerkulka sii kordhaya. Jaantuskan soo socdaa waxa uu tusinayaa agabka mishiinka wax-karinta-induction-ka ee tijaabada heerkulka. Isticmaalka dhabta ah, thermistor wuxuu si dhow ugu xiran yahay saxanka dhoobada, iyo dufan silikoon ah oo kuleyl leh ayaa lagu dabaqayaa barta xiriirka si loo hagaajiyo dareenka xakamaynta.
Cabbiraadda heerkulka makiinada wax-karinta guud ahaan waxay qabataa ogaanshaha dekedda A/D. Hadda chips badan ayaa leh shaqada ogaanshaha A/D. Thermistor NTC waxay si taxane ah ugu xidhan tahay iska caabin kale. Adigoo isticmaalaya mabda'a qaybinta danab iska caabinta, akhri qiimaha AD, qaybinta danabkuna waa la helay. Isbarbardhigga qiimaha ayaa qiimeeya heerkulka hadda jira. Heerkulbeegga makiinadaha induction ma cabbiro oo keliya heerkulka, laakiin sidoo kale wuxuu ilaaliyaa badbaadada. Marka heerkulku gaaro qiime cayiman, wareeggu si toos ah ayuu u gooyaa wax soo saarka, iyo soo saaraha guud wuxuu leeyahay cillad aan caadi ahayn oo ku jirta thermistor (Tusaale ahaan, marka wareegga gaaban ama wareegga furan uu dhaco, furaha qaladka u dhigma ayaa la soo bandhigayaa. si loo helo sababta si fudud inta lagu jiro dayactirka iyo kormeerka.
