NTC, PTC, PT100, 온도 프로브 센서용 DS18B20

NTC, PTC, PT100, DS18B20 Temperature probes and temperature sensors play an important role in the field of temperature measurement. The following is a detailed introduction to temperature probe sensors:

온도 센서에는 여러 유형이 있습니다, 포함:
열전대
These sensors are made of two dissimilar metals that connect at two points to form a junction. They are reliable, accurate, and can operate over a wide range of temperatures.

저항 온도 검출기 (RTD)
These sensors are based on the change in resistance of a metal as the temperature changes.
서미스터
These sensors use the temperature characteristics of semiconductor resistors, which change resistance as the temperature changes. Thermistors are sensitive and have high accuracy relative to their cost.

음의 온도 계수 (NTC) 서미스터
These sensors are sensitive and can respond to very small temperature changes. They have a temperature range of -50 ° C ~ 250 ℃.

Resistive temperature detectors
These sensors have positive temperature coefficients (PTC) and offer precise temperature measurements. 하지만, they have poor sensitivity.
