## About Thermocouple Voltage Calculator (Formula)

The Thermocouple Voltage Calculator is a tool used to determine the voltage output of a thermocouple based on the temperature difference between the measurement junction and the reference junction. It helps in converting temperature readings into corresponding voltage values. The calculation of thermocouple voltage involves the use of a thermocouple voltage-to-temperature conversion table or equation specific to the thermocouple type being used.

The voltage generated by a thermocouple is a function of the temperature difference between the two junctions and the thermoelectric properties of the specific thermocouple material. The thermocouple voltage can be determined using the appropriate thermocouple voltage-to-temperature relationship.

For example, using the linear relationship for a type K thermocouple:

**Voltage = (Temperature – Reference Temperature) * Voltage per Degree**

Where:

- Voltage represents the thermocouple voltage output, typically measured in millivolts (mV).
- Temperature refers to the measured temperature at the measurement junction, typically in degrees Celsius (°C) or Kelvin (K).
- Reference Temperature denotes the temperature at the reference junction.
- Voltage per Degree represents the thermoelectric voltage change per degree Celsius (°C) or Kelvin (K) for the specific thermocouple type.

To calculate the thermocouple voltage, subtract the reference temperature from the measurement temperature, and multiply the result by the voltage per degree.

It’s important to note that the specific voltage-to-temperature relationship and voltage per degree vary depending on the type of thermocouple being used, such as type K, type J, type T, etc. Therefore, it is necessary to consult the appropriate thermocouple voltage-to-temperature conversion table or equation specific to the thermocouple type to obtain accurate results.

The Thermocouple Voltage Calculator assists in converting temperature readings into corresponding thermocouple voltage values. It is widely used in various industries for temperature measurement and control applications, such as in industrial processes, scientific research, and heating/cooling systems.
