Comparison between PT100 temperature sensor probe and DS18B20 module
1) Basic principle of signal acquisition
① The resistance of PT100 changes proportionally with the temperature (the higher the temperature, the greater the resistance), but the resistance change is very small, sobre 0.385 O / degree;
NTC temperature sensor is a thermistor sensor (rang de mesura de temperatura: -30°C to +200°C (-22°F to +392°F) waterproof probe). Its resistance value changes with temperature. NTC (Negative Temperature Coefficient) means that its resistance value is negatively correlated with temperature, és a dir, as the temperature rises, the resistance value will decrease; a la inversa, as the temperature decreases, the resistance value will increase. This characteristic makes NTC temperature sensor very suitable for measuring temperature.
En aplicacions modernes de tecnologia de detecció, (NTC, PTC, PT100, termoparell, resistència tèrmica, DS18B20, etc. cable, kit de sonda) Els sensors de temperatura són eines clau de mesura. S'utilitzen àmpliament en l'automatització industrial, seguiment agrícola, fabricació d'automòbils i altres camps. Per garantir que el sensor de temperatura pugui funcionar de manera estable i fiable en un ambient humit o humit, waterproof and moisture-proof technology
The core technologies of sensor probes and temperature measurement cable kits involve temperature sensing, signal transmission and data processing. Temperature acquisition expert YAXUN uses high-precision Shibaura NTC thermistors for sensor temperature sensing harnesses, including sensing materials, signal processing technology, integrated design and future development trends.
