NTC thermistors for dryer heaters.Microwave Sensor Module Manufacturing

　　Clothes dryers are also commonly used clothes dryers. The working principle of clothes dryers is to dry clothes through hot air. Microcomputer automatic control is mostly used, and different drying temperatures and drying times can be configured according to drying requirements.

　　The dryer is equipped with a thermistor that monitors the air temperature in all drums to ensure clothes are dry and prevent the machine from overheating.

　　The NTC thermistor suitable for the dryer heater is the small leather wire NTC thermistor below.

　　1. High measurement accuracy

　　2. Tight tolerances for resistance and Beta values.

　　3. Fast response and small size.

　　4. It can run stably for a long time.

　　5. The rated resistance of 25C can be 1kΩ~1000kΩ.

　　6. Common resistance values at 25°C are: 1kΩ, 2kΩ, 2.252Ω, 3kΩ, 4.7kΩ, 5kΩ, 6.8kΩ, 10kΩ, 15kΩ, 20kΩ, 30kΩ, 40kΩ, 47kΩ, 50kΩ, 100kΩ, 150kΩ, 1000kΩ, etc.

　　7. Dissipation factor: ≥3.0mW/C in still air.

　　8. Thermal time constant: ≤12 seconds in still air.

　　9. Operating temperature range: -45°C - + 105°C.

　　Types of NTC temperature sensors suitable for power battery management systems

　　The power battery management system is referred to as the BMS system, which is mainly used for real-time monitoring of battery parameters, fault diagnosis, SOC estimation, mileage estimation, short circuit protection, leakage monitoring, display alarm, charge and discharge mode selection, etc.

　　We know that a cell is an electrochemical process. Multiple cells form a battery, and each cell has its own characteristics. No matter how precise the manufacturing is, there will be errors and inconsistencies in each cell with the time and environment of use. Therefore, the battery management system is to evaluate the current state of the battery through limited parameters.

　　In the power battery management system, there will be a built-in temperature sensing element NTC temperature sensor. In order to achieve the best accuracy and repeatability of battery temperature measurement, Minchuang Electronics has introduced a variety of NTC temperature sensors to adapt to different uses and temperatures to improve work efficiency.

　　Precautions when using NTC thermistor in power battery management system:

　　The reduction in resistance value caused by self-heating may cause the machine to malfunction. Do not apply excessive voltage to the thermistor. The type of load that generates inrush current, the amount of inrush current and time, etc., do not set parameters exceeding the specified parameters. .

　　Handling of thermistor elements after opening: After opening the smallest package, please reseal the product or store it in an airtight container with desiccant.
