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.

Features:

● High sensitivity and fast response
● Resistance value and B value have high precision, good consistency and interchangeability
● Using double-layer encapsulation technology, it has good insulation sealing and resistance to mechanical collision and bending resistance
● The structure is simple and flexible, and can be customized according to different design requirements of customers.

Application

● Air conditioners, refrigerators, freezers, water heaters, water dispensers, heaters, dishwashers, disinfection cabinets, washing machines, dryers and other home appliances.
● Automobile air conditioner, water temperature sensor, intake air temperature sensor, engine
● Switching power supply, UPS uninterruptible power supply, frequency converter, electric boiler, etc.
● Intelligent toilet, electric blanket, etc.

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.

Reliability Test

Dongguan Linkun Electronic Technology Co., Ltd. (Feiyang Electronics Factory) was established in 2004 and has developed into a large-scale professional development and production of a full range of varistors (Varistors), thermistors, PTC, NTC series, wave It is a protective component manufacturer of surge protectors and lightning protection products, ranking in the forefront of the same industry. PTC series has unique advantages in degaussing and current limiting heating, and NTC is particularly cost-effective in high-power resistors.
