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 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.
What is the function of thermocouple?
A thermocouple is a temperature sensor that produces a voltage proportional to the temperature difference between two junctions. This voltage can be measured to determine the temperature of the system being monitored. Thermocouples are commonly used in various industries for temperature measurement and control applications.
What instrument is most suitable for measuring a rapidly changing temperature.?
A thermocouple is a suitable instrument for measuring rapidly changing temperatures as it responds quickly to temperature changes due to its low thermal mass. Its small size also allows for quick response time.
When measuring temperature of 900 c the instrument used would be?
A thermocouple or a pyrometer would be used to measure a temperature of 900°C. These instruments are designed to withstand high temperatures and provide accurate temperature readings in such conditions.
How does a thermeter work?
A thermometer works by measuring temperature using a temperature-sensing element, such as mercury or a thermocouple. When the element is exposed to a change in temperature, it expands or contracts, producing a corresponding change in length that is displayed on a scale. The scale provides a numerical value to represent the temperature.

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 the function of a thermocouple in a temperature measurement system?
A thermocouple is a sensor that measures temperature by detecting changes in voltage caused by temperature differences between its two metal wires. It is commonly used in temperature measurement systems to provide accurate and reliable temperature readings.
Is thermocouple a temperature measuring device?
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 is the difference between thermocouple and RTD?
A thermocouple measures temperature difference between two points, producing a tiny voltage corresponding to the difference in temperature. To measure temperature with a thermocouple, you need to know the temperature of one junction and calculate the difference from the table or equation for the type of t/c used. An RTD changes resistance in response to temperature--to measure temperature with an RTD you measure its resistance (usually by putting a known voltage across it and measuring the current).
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.
