Waterproof NTC Temperature Sensor 10K B3977 Accuracy 1% Sealed Thermistor Probe

Waterproof NTC temperature sensor 10K B3977 accuracy 1% sealed thermistor probe

The accuracy of the temperature sensor should reach ±2%~±5%RH. If it cannot reach this level, it is difficult to use it as a measuring instrument. It is difficult for the temperature sensor to achieve the accuracy of ±2%~±3%RH. The given properties are measured at room temperature (20°C ± 10°C) and in clean gas. In actual use, due to the influence of dust, oil and harmful gases, aging will occur and the accuracy will decrease after a long time of use. The accuracy level of the temperature sensor should be judged in combination with its long-term stability. Generally speaking, long-term stability and use The lifespan is the first issue affecting the quality of the temperature sensor. There are very few products whose annual drift is controlled at 1%RH level, generally around ±2%, or even higher.

►Design considerations and procedure of temperature sensor:

1. Choose the shape acoording to customer's design or assemble requirements, and confirm the thermistor.
2. Confirm the thermistor element and other materials according to customers' requirement
3. Choose the suitable resistance,B value and tolerance
4. Choose suitable moisture-proof and insulation technology to meet customer's requirement
5. Choose suitable encapsulation structure to meet performance requirements of mechanical shock resistance
6. Meet customer's special requirements.

Product Description

Working principle of temperature sensor

Using the NTC thermistor under a certain measurement power, the resistance value drops rapidly as the temperature rises. Utilizing this feature, the NTC thermistor can be used to determine the corresponding temperature by measuring its resistance value, so as to achieve the purpose of detecting and controlling the temperature.
