Anslutningsmetoden för NTC-termistortemperaturgivaren måste bestämmas enligt det faktiska tillämpningsscenariot och mätkraven. Under ledningsprocessen, var noga med att vara uppmärksam på stiftets polaritet, val av tråd, temperaturintervall, filtrering och frikoppling, jordningsbehandling, och verifiering och kalibrering för att säkerställa mätningens noggrannhet och tillförlitlighet.
What are thermistors NTC and PTC?
NTC and PTC are both thermistors, which are special resistors that can change resistance with temperature. They can also be said to be a kind of sensor.
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% eller 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.
NTC temperature sensor is a thermistor sensor (mäta temperaturområdet: -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, som är, as the temperature rises, the resistance value will decrease; omvänt, as the temperature decreases, the resistance value will increase. This characteristic makes NTC temperature sensor very suitable for measuring temperature.
I moderna avkänningstekniska applikationer, (NTC, PTC, PT100, termoelement, termisk motstånd, DS18B20, etc. kabel, sondutsättning) Temperatursensorer är viktiga mätverktyg. De används allmänt i industriell automatisering, jordbruksövervakning, biltillverkning och andra fält. För att säkerställa att temperatursensorn kan fungera stabilt och pålitligt i en fuktig eller våt miljö, 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.

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.
