Thermocouple is a heat sensing device.
It is made up of 2 dissimilar metals twisted/joined at one end called a junction and that is made Hot and the other end or tell end is cold (may be at 0 degree C). then a voltage is developed accross the two dissimilar metal, this principle is called SEEBECK EFFECT.
The voltage developed is directly propersional to the difference in temperature.

is a thermocouple an active or passive transducer?-why?
Yes, it's an active transducer. A thermocouple is passive not active

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.
The thermocouple keeps a gas pilot light burning.

You should not paint a thermocouple.
not much, but it will depend on the type of thermocouple
Yes, it's an active transducer. A thermocouple is passive not active
The thermocouple is a sensore used to measure temperature. The thermocouple are made with two wires of different metals. joined together at one end to from a junction the thermocouple outputs in a a Milli volts .
The reference junction, also known as the cold junction, serves as the point where the thermocouple temperature is compared to the known temperature of the reference junction. This comparison helps to accurately determine the temperature at the measurement point. The reference junction compensation is required because the output voltage of the thermocouple is dependent on the temperature difference between the measurement point and the reference junction.
Cause: Poor thermocouple contactSolution: Check the thermocouple
To produce 230 volts using thermocouple action, you would need to connect multiple thermocouples in series to add up their voltages. Each individual thermocouple generates a small voltage, typically in the range of millivolts, so by connecting them in series you can sum up their voltages to achieve the desired 230 volts. Keep in mind that the number of thermocouples needed would depend on the voltage output of each thermocouple and the overall design of the setup.
