A thermocouple connection should be tight enough to ensure good thermal contact and to prevent any air gaps, which can affect measurement accuracy. However, it should not be overly tight, as excessive force can damage the thermocouple or its insulation. Typically, a snug fit is sufficient, allowing for reliable readings while preserving the integrity of the connection. Always follow the manufacturer's guidelines for specific torque recommendations.
You must use thermocouple wire (of the same type as the thermocouple) to extend the circuit. If you switch to a different wire the point of connection between the two becomes a thermocouple junction itself, and the resulting voltage from that junction will skew your reading. You can use any wire to extend a thermocouple connection if you know the temperature of the junction where the thermocouple wire ends--this becomes the reference junction.
The output of the thermocouple is linear.
Sometimes it can take up to TWO MINUTES for the thermocouple to take effect ( proof of flame) If the flame does not stay on the thermocouple should be replaced by a qualified licensed plumber
The thermocouple which measured the car's coolant temperature failed and so the car overheated.
The thermocouple is an sesnsing device , when the temperature increases it increases the voltage , that voltage is used for tripping purpose

You should not paint a thermocouple.

The thermocouple may continue to fail to stay lit due to a faulty connection, a buildup of dirt or debris, or a worn-out component.
A negative temperature reading in a J-type thermocouple can be caused by a reversed connection of the thermocouple wires, which leads to the temperature measurement being incorrect. Check the polarity of the wires and make sure they are correctly connected to avoid this issue.
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.
Control valves do go bad, but not that often. The tip of the thermocouple is in the flame? Holding the pilot button down long enough for it to heat? Sometimes the first time you light it, it takes a little longer for the thermocouple to work. Good clean connection on the valve end of the thermocouple? That's all I can come up with at the moment.

Yes, thermocouple is used in fridges !
it should be pretty tight, but no so tight that it stretches it
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.
Both tight and tightly may be used as adverbs: Be sure to pull the knot tight. /Pull tightly on the ends of the rope. Tight may also be used as an adjective, often metaphorically: We were on a tight schedule. / It was a tight fit. / He was in a tight spot. A tight connection is required on all cables.
