NTC Thermistors 2.5Ω, 5Ω, 10Ω, 100Oh & 3950, 3435

Resistance Range and Application of Thermistors

‌ The resistance range of thermistors is wide, and the resistance of NTC thermistors can range from tens of ohms to ten thousand ohms, and even special devices can be customized according to needs. Commonly used resistance values ​​are 2.5Ω, 5Oh, 10Oh, itd., and common resistance errors are ±15%, ±20%, ±30%, itd. The resistance range of PTC thermistors is usually from 1KΩ to hundreds of KΩ.

Accuracy and Response Time of Thermistor Sensors

‌Reasonable arrangement of temperature sensors‌: The location and arrangement of temperature sensors will also affect the response time. If the contact area between the sensor and the object being measured is large, the heat exchange will be faster and the response time will naturally be shorter. Međutim, please note that too large a contact area may also lead to increased measurement errors, so we have to make a trade-off based on the actual situation.

Wiring of NTC Thermistor Temperature Sensor

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, temperaturni opseg, filtering and decoupling, grounding treatment, and verification and calibration to ensure the accuracy and reliability of the measurement.

Razlike između Pt100 i Pt1000 senzora

Glavna razlika između Pt100 i Pt1000 senzora je njihov nominalni otpor na 0°C, sa Pt100 koji ima otpor od 100 oma i Pt1000 koji ima otpor od 1000 ohms, što znači da Pt1000 ima znatno veći otpor, što ga čini pogodnijim za aplikacije u kojima je potrebno precizno mjerenje temperature uz minimalan utjecaj otpora olovne žice, posebno u 2-žičnim konfiguracijama kola;

Koja je razlika između 2-, 3-, i 4-žični RTD senzori?

Ovaj članak istražuje 2-, 3-, i 4-žične konfiguracije za otporne temperaturne detektore (RTDs), fokusirajući se na faktore životne sredine, zahtjevi za tačnost, trošak, i konfiguracija žice utječu na odabir. 4-žična konfiguracija je složena, ali nudi najveću preciznost, dok 2-žična konfiguracija ima prednosti u aplikacijama niže preciznosti. Odabir konfiguracije zahtijeva kombinaciju zahtjeva primjene i praktičnih uvjeta.
