As a component that can change the resistance value according to temperature changes, thermistors have a wide range of applications (such as temperature measurement, temperatuuri reguleerimine, temperatuuri kompenseerimine, temperature alarm, battery thermal protection). Let me share with you several application cases of thermistors:
The connection method of the NTC thermistor temperature sensor needs to be determined according to the actual application scenario and measurement requirements. During the wiring process, be sure to pay attention to the pin polarity, wire selection, temperatuurivahemik, filtering and decoupling, grounding treatment, and verification and calibration to ensure the accuracy and reliability of the measurement.
Mis on termistorid NTC ja PTC?
NTC ja PTC on mõlemad termistorid, mis on spetsiaalsed takistid, mis võivad temperatuuriga takistust muuta. Võib ka öelda, et need on omamoodi andurid.
K: Kas saate tundlikkuse eraldusvõimet üksikasjalikumalt selgitada? Miks on kõrgemad väärtused paremad?
A: Kõrge tundlikkus välistab igasuguse plii takistuse. See lihtsustab ka toetavat elektroonikat. A 10,000 Ohm termistor muudab takistust võrra 4.4% või 440 oomi 1°C temperatuurimuutuse korral. A 100 oomi plaatinaandur muudab takistust võrra 1/3 oomi 1°C temperatuurimuutuse korral.
NTC temperature sensor is a thermistor sensor (temperatuurivahemik: -30°C to +200°C (-22°F to +392°F) waterproof probe). Its resistance value changes with temperature. NTC (Negatiivne temperatuurikoefitsient) means that its resistance value is negatively correlated with temperature, see tähendab, as the temperature rises, the resistance value will decrease; vastupidi, as the temperature decreases, the resistance value will increase. This characteristic makes NTC temperature sensor very suitable for measuring temperature.
Kaasaegsetes sensortehnoloogia rakendustes, (NTC, PTC, PT100, termopaar, termotakisti, DS18B20, jne. kaabel, sondi komplekt) temperatuuriandurid on peamised mõõtmisvahendid. Neid kasutatakse laialdaselt tööstusautomaatikas, põllumajandusseire, autotootmine ja muud valdkonnad. Et tagada temperatuurianduri stabiilne ja töökindel töötamine niiskes või märjas keskkonnas, vee- ja niiskuskindel tehnoloogia
Andurisondide ja temperatuuri mõõtmise kaablikomplektide põhitehnoloogiad hõlmavad temperatuuri tuvastamist, signaali edastamine ja andmetöötlus. Temperatuurihõiveekspert YAXUN kasutab ülitäpseid Shibaura NTC termistore andurite temperatuurianduri rakmete jaoks, sealhulgas sensormaterjalid, signaalitöötlustehnoloogia, integreeritud disain ja tulevased arengusuunad.

PTC linear positive temperature coefficient thermistor is made of PTC material and physical process. It has excellent stability and complex linearity. The characteristic curve remains unchanged after millions of repetitions. The resistance value increases with the temperature, changes linearly, and has good linearity. Compared with the thermistor synthesized by PTC polymer ceramics, it has good linearity and does not require linear compensation measures to simplify the circuit design. It also has good resistance consistency, strong interchangeability, and standardized appearance and specifications. The temperature sensing speed is fast, 1-2 seconds in air medium, and has high sensitivity. It is small in size, sturdy in structure, and standardized in appearance, suitable for automated installation of printed circuit boards.
