NTC is called a negative temperature coefficient thermistor. It is prepared from the ceramic material formed by the oxides of the MN-Co-NI. The characteristics of small and fast response to various temperature changes can be used to be used as high -sensitivity, high -precision temperature sensors, and are often used as real -time temperature monitoring and temperature compensation in electronic circuits.
The hot time constant is the basic feature of a thermistor, and the response time will depend on the thermistor of the selected. Different thermistor resistance has different thermal time constants, each will generate different hot time constants and different response time.
The larger the thermistor, the slower the response time. Therefore, the smaller the response time.
Therefore, when selecting NTC thermistor for the application, the following points should be considered;
1. The type of thermistor to be used,
2. The required response time needs to meet your application requirements.
3. You can see how this information affects results related to your application. Finally, if you choose the correct thermistor, your results will be positive. However, if you choose the wrong thermistor, it may cause the response time to be too fast or too slow.
4. No matter what ways, the response may cause system failure. As a result, you may encounter the operating costs caused by the system stop and any modification you may make. For more information about the heat time constant and equation, Wikipedia provides a good source of additional information.
NTC temperature sensor hot and cold impact test
The hot and cold impact test is also called the temperature impact test. It is used to test the material structure or composite material. In an instant, the degree of tolerance can be tolerated under the continuous environment with high temperature and extremely low temperature. Chemical changes or physical damage caused by shrinkage, confirm the quality of the product. It is an indispensable test in the test test of the equipment design and the routine test of the batch stage. In some cases, it can also be used for environmental stress screening tests. It can be said that the frequency of the application of the hot and cold impact test box in terms of verification and improvement of the environmental adaptability of equipment is second only to vibration and high and low temperature tests.
The temperature sensor is an important core component in the temperature controller kit. How to ensure the quality of the temperature sensor and how to reduce the related after -sales costs caused by the damage of the sensor. These problems are all used as professional controller and sensor manufacturers. On the occasion, the important factor in choosing a supporting product is appropriate. From the perspective of solving the actual problem of customers, consider the role of temperature sensors for the quality of the quality of the quality. Therefore, it is very important to conduct a hot and cold impact test on the temperature sensor.
