No, by itself a thermocouple can only measure temperature difference between two points (junctions) in a circuit. To use a thermocouple as a temperature sensor, you must know the temperature of one junction by some other means. Often an additional temperature sensor is used. However, in some applications temperature difference is enough. For example, in gas appliances a thermocouple detects presence of a flame because the flame is much hotter than room temperature-- you don't need to actually measure the flame temperature.

Yes, it is. If you look up "thermocouple" in Wikipedia, you will find a very detailed
explanation of how and why they work.

How does temperature measured in thermocouple?
According to Wikipedia, a thermocouple is a temperature-measuring device consisting of two dissimilar conductors that contact each other at one or more spots. It produces a voltage when the temperature of one of the spots differs from the reference temperature at other parts of the circuit. The voltage is converted to a temperature. There are many different designs depending on the pair of conductors used.
What kitchen utensil is used for measuring temperature?

State 5 type of temperature measuring devices other than thermocouple with its application?
RTD - Resistence temperature detector Thermistor Pyrometer Thermometer
How does a car outside temp sensor work?
The sensor can either be an RTD, resistive thermal device or a thermocouple. In the case of RTD, the resistance of the device changes with the temperature. This resistive value is sent to a calibrated meter or gauge. A RTD device is far more accurate than a thermocouple. Plus or minus .1 of 1%. In the case of a thermocouple a small voltage is created by the device which varies with the temperature. This is sent to the reading device or gauge. Plus or minus 2 0r 3 degrees.
