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.

What does a thermocouple do and how does it function in measuring temperature?
A thermocouple is a device that measures temperature by detecting changes in voltage when there is a difference in temperature between two different metals. When one end of the thermocouple is heated or cooled, it creates a voltage that is proportional to the temperature difference. This voltage is then converted into a temperature reading by a thermometer or temperature controller.
What do you use a THermocouple for?
measuring temperature difference
How a thermocouple device works?
A thermocouple consists of two different metals joined at one end, known as the hot junction, and connected to a temperature measuring device at the other end, called the cold junction. When there is a temperature difference between the two junctions, a voltage is generated due to the Seebeck effect. This voltage is then measured by the temperature device and converted into a temperature reading.
Which instrument is used for measuring very high temperature?
A thermocouple can be used.
What is thermocouple cable?
The thermocouple is an sesnsing device , when the temperature increases it increases the voltage , that voltage is used for tripping purpose
What is a device for measuring temperature?

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 is the mill volt reading of a good thermocouple?
A good thermocouple typically reads around 1 to 30 millivolts when exposed to its rated temperature range. The exact millivolt reading can vary depending on the type of thermocouple and the temperature it is measuring.
What is used for measuring temperature?
Temperature is typically measured using a thermometer, which can be digital or analog. There are various types of thermometers, such as mercury, infrared, and thermocouple, each with different methods for measuring temperature.
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.
