As a component that can change the resistance value according to temperature changes, thermistors have a wide range of applications (such as temperature measurement, temperature control, temperature compensation, 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, temperature range, filtering and decoupling, grounding treatment, and verification and calibration to ensure the accuracy and reliability of the measurement.
Co jsou Termistory NTC a PTC?
NTC a PTC jsou termistory, což jsou speciální rezistory, které mohou změnit odpor s teplotou. Lze je také říci, že jsou jakýmsi senzorem.
Q: Can you explain sensitivity resolution in more detail? Why are higher values better?
A: High sensitivity eliminates any lead resistance. It also simplifies the supporting electronics. A 10,000 ohm thermistor changes resistance by 4.4% nebo 440 ohms for a 1°C change in temperature. A 100 ohm platinum sensor changes resistance by 1/3 ohm for a 1°C change in temperature.
Comparison between PT100 temperature sensor probe and DS18B20 module
1) Základní princip získávání signálu
① Odpor PT100 se mění úměrně s teplotou (čím vyšší je teplota, Čím větší je odpor), Změna odporu je však velmi malá, o 0.385 Ó / stupeň;
NTC temperature sensor is a thermistor sensor (měření teplotního rozsahu: -30°C to +200°C (-22°F to +392°F) waterproof probe). Its resistance value changes with temperature. NTC (Koeficient záporné teploty) means that its resistance value is negatively correlated with temperature, to je, as the temperature rises, the resistance value will decrease; conversely, as the temperature decreases, the resistance value will increase. This characteristic makes NTC temperature sensor very suitable for measuring temperature.
In modern sensing technology applications, (NTC, PTC, PT100, termočlánek, thermal resistor, DS18B20, atd. cable, probe kit) temperature sensors are key measuring tools. They are widely used in industrial automation, agricultural monitoring, automobile manufacturing and other fields. In order to ensure that the temperature sensor can work stably and reliably in a humid or wet environment, waterproof and moisture-proof technology
