If the pilot flame is too high a thermocouples life could be shortened. Check the specs of the unit supplied by the gas valve for the working pilot pressure. Or put the gas valve in pilot and depress the pilot push button. Keep the button down with a small screwdriver, remove the thermocouple from the gas valve and check the millivolts on the thermocouple. Place one lead on the copper tubing and the other lead on the end of the thermocouple, the silver looking part that touches the inside of the gas valve. With the pilot flame on you should read anywhere from 22-29 millivolts. Anything below that is a sign that your thermocouple is failing. It might work for awhile, but it will probably go out in the middle of a long cold winter night. ;)

If a Salamander Grill keeps going out and the thermocouple is okay and the valve is new then a faulty thermostat could be the cause. Replacing the thermostat or re-calibrating it generally solves the issue.
No, that is part of the function of the pilot light. To light the burner and to keep the gas valve open. The thermocouple sits in the flame of the pilot and produces a small electrical current that keep the gas valve open. When the tank cools down, the thermostat opens the valve to the burner so that it can light. When the pilot goes out, it is usually the thermocouple that is bad.
The thermocouple is going bad. The thermocouple is the small tube that sits in the flame from the pilot light and goes back to the gas valve. They are easy to replace and cost $6 to $8. For health and safety the failing part should be replaced without delay by a competent gas engineer.
The thermocouple is two dissimilar pieces of metal inside a tiny metal bulb. When heated they then generate a tiny electrical charge that gives a signal to the gas regulator to keep the pilot on.
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.
You need a new 'thermocouple' . -Less than an hour's work for a competent handyman or gas fitter. The part costs less than $10.
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.
Not usually. Probably a bad or dirty thermocouple.
The thermocouple keeps a gas pilot light burning.
