Σύγκριση μεταξύ του αισθητήρα θερμοκρασίας PT100 και της ενότητας DS18B20
1) Βασική αρχή της απόκτησης σήματος
① Η αντίσταση του PT100 αλλάζει αναλογικά με τη θερμοκρασία (Όσο υψηλότερη είναι η θερμοκρασία, Όσο μεγαλύτερη είναι η αντίσταση), Αλλά η αλλαγή αντίστασης είναι πολύ μικρή, για 0.385 Ω / βαθμός;
NTC temperature sensor is a thermistor sensor (εύρος θερμοκρασίας μέτρησης: -30°C to +200°C (-22°F to +392°F) waterproof probe). Its resistance value changes with temperature. NTC (Αρνητικός συντελεστής θερμοκρασίας) means that its resistance value is negatively correlated with temperature, that is, 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, θερμοστοιχείο, thermal resistor, DS18B20, και τα λοιπά. καλώδιο, 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
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.
