Digital display characteristics and working principle of bimetallic thermometer

Digital display bimetallic thermometer when use can directly show the temperature, the use of more convenient for users, and its application range is wide, let our specific see on its use features and working principle are introduced. 1, the application characteristics of the digital display bimetallic thermometer when use is very safe and reliable, able to detect the temperature of the more accurate numerical, and it USES a very high quality material, resistant to corrosive medium, own have very long service life. 2, the principle using temperature sensitive element is the temperature sensor ( Such as platinum resistance, thermocouple, semiconductor, thermistor, etc. ) Would change, the change of temperature into electrical signals, such as the change of the voltage and current, the temperature change and the change of the electrical signal has a certain relationship, such as linear relationship, the curve of a certain relationship, and so on, the electrical signal can be used in adc circuit that AD conversion circuit converts analog signals to digital signals, the digital signal to send to processing unit, such as SCM and PC, processing unit through internal software calculation will be linked to the digital signal and temperature, temperature can be displayed values, such as 25. 0 degrees Celsius, and then through the display unit, such as the LED, LCD or computer screen display observation to the person. This completes the basic temperature measurement functions of the digital thermometer. With more and more digital display of the bimetallic thermometer application, also appeared on the market a lot of related products, users also need to consider when the choice of its parameters, and see if it is meet its application requirement.
