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

Air Probe.
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.
is a thermocouple an active or passive transducer?-why?
The thermocouple keeps a gas pilot light burning.
You should not paint a thermocouple.
A thermocouple in a gas furnace is a safety device that detects if the pilot light is on. If the pilot light goes out, the thermocouple shuts off the gas supply to prevent a dangerous gas leak. This helps ensure the furnace operates safely and efficiently by preventing the buildup of gas without ignition.
To test a thermocouple on a water heater, you can use a multimeter to measure the voltage output. Disconnect the thermocouple from the control unit and place the multimeter probes on the thermocouple terminals. A functioning thermocouple should produce a voltage reading within the expected range. If the reading is outside this range, the thermocouple may need to be replaced.
Yes, it's an active transducer. A thermocouple is passive not active
not much, but it will depend on the type of thermocouple
To determine if a thermocouple is bad, you can use a multimeter to measure the voltage output when the thermocouple is heated. If the voltage reading is not within the expected range, it may indicate that the thermocouple is faulty. Additionally, visually inspecting the thermocouple for any signs of damage or wear can also help determine if it is bad.
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 .
