2.Functional features

Temperature measurement:The module is able to sense temperature changes and convert them into digital signal output through thermocouple or millivolt signal input.Thermocouple is a temperature sensor that uses the thermoelectric effect between two different metals to measure temperature.When the temperature changes,the thermocouple generates a voltage signal proportional to the temperature change.

Signal processing:The module may have signal processing functions such as amplification,filtering,and digitization to improve measurement accuracy and stability.

Output interface:The module usually has an output interface that can output digital signals to other devices or systems for display,control or recording.

3.Working principle

Thermocouples are made by connecting one end of two different metal materials together and the other end to a terminal above,and then using a voltmeter to measure the voltage across the terminals.When the materials of the two wires are different and the cold end temperatures of the two wires are also different,it means that the number of free electrons is different,and the voltmeter can measure the voltage value at this time.The 3HNA023093-001 thermocouple/mV input module directly measures the temperature and converts the temperature signal into a thermoelectric force signal,which is then converted into the temperature of the measured medium through an electrical instrument(secondary instrument).

4.Application scenarios
