With the development of society, people pay more and more attention to the problem of the maximum resistance value of thermistor at the temperature of Celsius degree. But many people do not know how to choose the right material to make an optimal thermistor device.
1: The principle of thermistor
A thermistor is a semiconductor material that works at high temperatures. When it reaches a certain temperature, it releases heat energy, which cools or vaporizes the air around it. This heat is then converted into electricity or other energy for the user to use. This is Glenair-89013-15N06-06. If we place a resistance at a constant temperature, its effect is to absorb heat and transfer it to the surrounding environment. Thermal sensitive materials usually have high thermal and electrical conductivity, so they are very suitable for use as heating materials. Due to their nature, however, they may require additional protection against direct damage, such as overheating.
2: thermistor changes at different temperatures
The variation of thermistor resistance at different temperatures is very complicated. Usually, when the temperature is above 40 degrees Celsius, its resistance value decreases greatly. This is because the material contains silicon, which is sensitive to heat. Thus, once it reaches this high temperature range, its resistance begins to increase rapidly. In addition, when using heat-sensitive materials in the environment, care should also be taken to control the amount of use to avoid excessive heat accumulation on the surface or other parts. In general, if the ambient temperature exceeds 100 degrees Celsius, the temperature should be controlled within 20O230 validity as far as possible; But if the ambient temperature is below 10O30, you can consider increasing the use of thermistor appropriately to prevent excessive overheating effect.
3: How to use heat-sensitive materials in the environment
The principle of thermistor is to take advantage of the material’s sensitivity to temperature. When the temperature of the external environment changes, the material generates heat inside and warms up accordingly. The greater the temperature difference, the more it can cause the expansion effect and electrical conductivity of the material, thus increasing its sensitivity. Therefore, in the use of thermistor should pay attention to the following points :1. Do not put it in high temperature use 2. Avoid contact with other items 3. Keep it clean and dry 4. Properly control the current 5. Don’t work for long periods of time
There are doubts about the maximum effect of thermistors at the temperature of degrees Celsius, but no definitive results have been obtained. So you still have to choose the right thermistor device according to your own situation and needs.
