You don't, a thermocouple's output is in the millivolt range.
In effect it does. Electricity applied to the heater produces heat. Heat applied to the thermocouple produces electricity.
thermocouple part no o62790
200-300$ a pop <><><> A thermocouple is just two wires of different metals, joined at one end. If you know the wire materials for the type thermocouple you want, you can weld the tips together so the cost is in the wire. Fancier store-bought thermocouples can have color-coded wire, insulated junctions and other features that add to the price.
modern heaters have a thermocouple that would shut off gas supply if the pilot goes out.

it is use measure the tempreture wheel spce.
The thermocouple does not actually measure temperature, but the temperature difference between two points. If the temperature at one point is known (reference junction) then the temperature of the other point (sensing junction) can be calculated.
The output of the thermocouple is linear.
Yes, thermocouple is used in fridges !
To create a thermocouple one needs thermocouple wire, a means of spot welding the wire, and wire strippers. A thermocouple is used to measure temperature.
Very simple answer: to make a hole in a cork or plastic stopper; the scope is to insert a tube, thermocouple, thermometer, etc.
The thermocouple keeps a gas pilot light burning.
is a thermocouple an active or passive transducer?-why?
You should not paint a thermocouple.
There are a few potential advantages of a K Type Thermocouple. These advantages include being able to measure extremely high temperatures up to 2,600 degrees C. It can also function in cold rugged conditions below -100 degrees.
