Saat memilih termistor, memang perlu untuk secara komprehensif mempertimbangkan banyak parameter dan pengemasan utama (enkapsulasi resin epoksi, Enkapsulasi manik kaca, Enkapsulasi film tipis, Enkapsulasi SMD, enkapsulasi sensor probe stainless steel, lapisan cetakan injeksi). Izinkan saya memberi tahu Anda secara detail:

‌ 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, dll., and common resistance errors are ±15%, ±20%, ±30%, dll.. The resistance range of PTC thermistors is usually from 1KΩ to hundreds of KΩ.

‌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. Namun, 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.

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, kompensasi suhu, 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, kisaran suhu, filtering and decoupling, grounding treatment, and verification and calibration to ensure the accuracy and reliability of the measurement.
