The core function of the temperature sensor in the hair dryer
Safety Assurance: From Overheating Power Off to Active Prevention This is the most fundamental and important significance of the sensor. Preventing Machine Self-Combustion: When the internal air duct is blocked or the fan fails, the heat generated by the heating element cannot be dissipated, caus...Read more -
The NTC SENSOR in the hair dryer and its differences and technologies
The core differences among the three types of temperature sensors 1. Basic Protection Type (Suitable for most traditional hair dryers) Main technical/sensor types: NTC thermistor, temperature control fuse Core functions and purposes: Prevent overheating of the body or the outlet, ensuring basic s...Read more -
The core and working principle of magnetic control switch technology
You may have noticed that the implementation methods of magnetic control switches are diverse, but they are mainly based on two core components: Pneumocouple: A small glass tube filled with inert gas and containing metal spring plates inside. When an external magnet approaches, the spring plates ...Read more -

Type of car seat heating sensor
Type: The majority of them use NTC thermistors. Their characteristic is that the resistance decreases as the temperature rises. This enables the ECU to precisely calculate the current temperature by measuring the resistance value of the circuit. Location: The sensors are usually sewn or adhered t...Read more -
Analysis of the automotive seat heating sensor
What is an automotive seat heating sensor? The automotive seat heating sensor is a crucial safety and control component in the seat heating system. It is usually a negative temperature coefficient thermistor, whose main function is to monitor the temperature of the seat surface in real time and f...Read more -
The functions of the compressor and the heating tube at each stage
The system switched the flow direction of the refrigerant through a component called “four-way valve”. At this point, the compressor still compressed the refrigerant into a hot and high-pressure gas, but it was first pumped into the heat exchanger of the indoor unit (which functioned ...Read more -
How do the compressor and the heating tube work together?
The compressor and the heating tube are two components with completely different functions, and they play a core role in the cooling and heating systems. Their “cooperative operation” is mainly manifested in the heat pump system of air conditioners. To ensure a thorough understanding,...Read more -
Common types and locations of heating tubes found in refrigerators
There is usually not just one heating tube in the refrigerator, but they are distributed in different positions according to their functions. 1. Frost-removal heating tube – The most important heating tube Position: Close to the bottom of the evaporator or interspersed among the evaporator ...Read more -
Why does a refrigerator need a heating element?
This might sound counterintuitive – why would a cooling device need to be heated? The key lies in defrosting and preventing moisture. 1. Defrosting (for air-cooled refrigerators): The air-cooled refrigerator uses a fan to blow the cold air from the evaporator into the compartments. When the...Read more
