Linear voltage of thermocouple 20mv to 50mv temperature between 750 to 1250 degree Fahrenheit how much voltage will be generated at 1000 degree Fahrenheit?

Well, honey, the voltage generated by the thermocouple is directly proportional to the temperature difference. So, if the temperature range is 500 degrees Fahrenheit (1250 - 750), and the voltage range is 30mV (50 - 20), you can calculate the voltage generated at 1000 degrees Fahrenheit using a simple proportion. Just plug in the numbers and you'll get your answer, darling.
