何时使用 NTC 热敏电阻探头以及为什么需要它 维连温度传感器When to use the NTC thermistor probe and why do it need it

NTC thermistor resistance has endless application
NTC thermistor probe can measure the level and temperature from automotive electronics to medical technology to green energy industry. Their applications are endless, and their goals ensure the operability of their applications.

Thermoltic resistance probe can also be the same NTC thermistor resistance chip, which is encapsulated with epoxy resin or glass. Alternatively, it can be packaged in a metal or plastic case with two high -temperature insulated wires.

These NTC thermal resistances are all places where we live and work. From the moment we wake up to cook coffee until we get home and relax in front of the TV, we ends. They are essential for our vehicles we go to work, the computer needed for work, and the equipment we use to prepare food at the end of the day.

Understanding temperature sensing probes and its applications
Understanding the working principle, capacity, and potential of NTC thermist resistance probe is essential. Part of this understanding includes the electrical characteristics of the probe that follows certain operating principles, including resistance, response, and pressure and thermal conductivity.

In view of their universality and application scope, although there are many thermist resistance size and shapes, it is impossible to create universal NTC thermistor resistance probe components. The temperature sensor used in the car is different from the temperature sensor used in the wind turbine.

Thermoltic resistance probe in car innovation

If there is no thermistor temperature sensing probe, many cars, electrical appliances, industrial equipment and anything that need to be controlled will not run normally, or they cannot run at all. The engineer uses these NTC thermistor sensors as any design considerations to produce products that generate heat or cold energy and require temperature measurement, compensation and control.

In 1966, about two thermal resistance per unit of the car was used. In the 1990s, this number increased to 60 thermistor, and today, 80 to 100 NTC thermistor among a car. The exponential growth of the temperature sensing equipment is parallel with the complexity and refinement of technology. With the increase and improvement of automotive technology, the demand for temperature sensors is also increasing. Car seat heater, air conditioner, window cream device and oil thermometer need to be detected, adjusted and temperature control. Now, as electric vehicles become more and more common, the use of NTC thermal resistance is more than ever before. In the past 7-10 years, lithium ion batteries in cars have become more economical. Thermal resistance is important to maintain the ideal battery temperature in the process ç Charging and discharge cycle.

Improvement technology allows more functions and processes to be accurate and reliable temperature sensing. For example, the thermostat used to measure the temperature of the cooling solution and control the cabin climate; today, the thermistor has replaced the thermostat because the thermistor is faster, more accurate, and more reliable. The NTC sensor can also detect the oil level and viscosity, reminding the driver when needed to be replaced.

Medical technology
医疗技术 维连温度传感器
Today, especially during the COVID-19 period, thermal resistance probes play a vital role in medical technology. The ventilator is a machine to help patients breathe. For a healthy person, the interior of the nose and mouth will heat and humidify the air we breathe, so that it can reach the body temperature, about 37 ° C. When patients have respiratory failure, they are like coronary virus, breathing opportunities to breathe for them. For such tasks, the temperature sensor must be accurate, sensitive and responding rapidly. At a discrete temperature sensor analyzes the air temperature and send a signal to the respirator to ensure that the airflow is appropriate.

Thermal resistance also works in the assessment of the heart infusion. Thermistor resistance forms a tip of the SWAN-Ganz catheter. After the cold solution is injected into the blood, the doctor uses thermal resistance to detect changes in blood temperature. Doctors can calculate the blood volume of the heart pumping in a certain time range. Similarly, temperature sensing equipment must be very accurate to detect slight changes in temperature.

Green Energy

Green energy is a field of great progress in the use of thermistor probe probe. In 2007, a team in Japan used NTC thermistor to create a better brake system for small wind turbine. The traditional disconnection circuit damage the turbine rotor and the generator winding through short -circuit current. The use of NTC thermistor is safer and more cost -effective in the disconnect circuit. The NTC probe can also measure the temperature of the leaves in the cold environment. When the blade of the wind turbine is frozen, the turbine is inefficient and cannot run. The NTC probe passes the temperature information to the heater of the wind turbine, so that the turbine can compensate for low temperature and prevent the leaves from freezing.

NTC Thermoltage resistance temperature sensor can also measure water temperature to analyze the rising global temperature. Through accurate, reliable and stable data testing, environmental scientists can determine the speed of warming the ocean and lakes. NTC thermistor is another excellent choice for this application, because they can maintain accuracy for a long time, thereby reducing the possibility of data collection interruption and leaning.

Daily Application
From the freezer to the portable heater, almost all electrical appliances have NTC thermistor. In terms of prevention capabilities, thermistor reduces the possibility of overheating and fire in the instrument (such as a microwave oven or portable heater). Other electrical appliances include computers, air conditioners and fire alarms.

How to choose armistor probe and integrate it into different applications
Similar to unlimited applications that require NTC thermistoric resistance probe components, there are many ways to install, paste and apply them. The shells and installations of some probe components can be complicated from simple to very complicated.
When talking about probes, metal or plastic component cases cover the bead -like heat -sensitive resistance for different applications and functions. These probes have various shapes, sizes and installation options. Some NTC thermal resistance probes are long and narrow, with stainless steel shells for vehicles to measure oil or water temperature. Other temperature sensing probes integrate threads used for engines or medical equipment to detect and monitor temperature. The probe with a ring -shaped wire design is usually used with the radiator or lithium -ion battery.

Each thermistor temperature sensor starts with a miniature chip connected to two thermal lines. Glass or metal shell covers probes. At the same time, heat -conducting epoxy resin fills the remaining space in the shell. The probe is further customized according to the precise requirements of its application. When used with applications such as lithium -ion batteries, the NTC probe with ring -shaped wires can be easily installed on the battery terminal. The probe component effectively monitor the battery temperature, so it will not rise to the working temperature or safety temperature.
