This sensor can be used in various environment, such as intelligent home applications, automotive applications, building automation, etc. It can be used to measure the precision, accuracy and repeatability of temperature for industrial applications. BR42KB504M can also be used in medical applications, such as medical thermometer and smart medical devices.With the application of BR42KB504M, many industrial processes are optimized. It helps to control the air in plant and factory, and optimize the temperature control in the production processes. Also, BR42KB504M is a common sensor for environmental monitoring applications, such as air quality, temperature, humidity and soil moisture.Working Principle
BR42KB504M is a temperature sensor based on NTC Thermistors that works on the principle of thermocouple. Thermistors are materials resistant to current alter with temperature. The NTC Termistor includes two parts: a semiconductor chip and a metal resistance material. As the temperature increases, the resistance of the thermistor decreases. The current passing through the thermistor is proportional to the temperature changes and the output current is proportional to the temperature changes.The working principle of BR42KB504M is simple: when the temperature increases, the resistance of the thermistor increases and the output current decreases; when the temperature decreases, the resistance of the thermistor decreases and the output current increases. The output of the BR42KB504M is suitable for a wide range of temperature measurement applications, with measuring range from -20°C to + 70°C and accuracy up to 0.1°C.Conclusion
BR42KB504M is a type of Temperature Sensors - NTC Thermistors. It could be used in a wide range of environment, such as intelligent home applications, automotive applications, building automation and medical applications. And it works on the principle of thermocouple. Its output current is proportional to the changes of temperature and the measuring range is from -20°C to + 70°C. With its unique features and accuracy, BR42KB504M is an ideal choice for a wide range of temperature measurement applications.
