What are the input and output signals of thermocouples and thermal resistance thermometers?
According to the principle, they are millivolts and resistance respectively
Thermal resistors are in ohms, while thermocouples are in millivolts
Thermocouples and thermal resistors do not have input issues; thermocouples output mV signals； The thermoresistor outputs an Ω signal....
The input signal is the quantity being measured that acts on the sensor – for a temperature sensor, the input signal is the temperature. The output signal is the response of the sensor – for a thermistor, the output signal is the resistance value; for a thermocouple, the output signal is the voltage value. Please forgive the modifications made by the person above: lol
Thermocouples generate mV signals; they exploit the difference in electron movement caused by temperature between two different metals to produce a thermoelectric voltage difference. A thermistor is a resistance signal; the resistance of a conductor varies depending on the temperature, and temperature is measured based on this corresponding relationship.
The thermocouple output is a millivolt signal, while the thermal resistor output is a resistance value
