How to control temperature of surface of rotating drum when you can't use thermocouple because it is stationary?

Use a non-contact method such as infrared to measure the drum temperature, or mount a wireless, battery powered temperature transmitter to the drum.

For most conductors as their temperature increases their resistance?
The resistance of pure metallic conductors increases with temperature, because the resistivity of these conductors increase with temperature.
How commutator converts AC to DC?
There is no conversion of AC to DC a commutator is the key to creating straight DC voltage. "The commutator rotates with the loop of wire just as the slip rings do with the rotor of an AC generator. Each half of the commutator ring is called a commutator segment and is insulated from the other half. Each end of the rotating loop of wire is connected to a commutator segment. Two carbon brushes connected to the outside circuit rest against the rotating commutator. One brush conducts the current out of the generator, and the other brush feeds it in. The commutator is designed so that, no matter how the current in the loop alternates, the commutator segment containing the outward-going current is always against the "out" brush at the proper time. The armature in a large DC generator has many coils of wire and commutator segments. Because of the commutator, engineers have found it necessary to have the armature serve as the rotor(the rotating part of an apparatus) and the field structure as the stator (a stationary portion enclosing rotating parts). Which is the inverse of an AC Generator."
Why does dew point change day to day?
Because the temperature changes and the dew point is dependent on the temperature.
What other evidence could explain how day and night occured when the tilt of earth's axis happened?
The Earth was probably rotating before that because not to rotate is a special case that is unlikely to occur.
Why Lucknow has a greater range of temperature than thiruvananthapuram?
because it is near the cost
Why can a satellite be stationary above the earths surface?
It appears stationary because it is moving around the Earth at the same rate that the Earth is rotating about its axis.
Is thermocouple a temperature measuring device?
No, by itself a thermocouple can only measure temperature difference between two points (junctions) in a circuit. To use a thermocouple as a temperature sensor, you must know the temperature of one junction by some other means. Often an additional temperature sensor is used. However, in some applications temperature difference is enough. For example, in gas appliances a thermocouple detects presence of a flame because the flame is much hotter than room temperature-- you don't need to actually measure the flame temperature. ====================== Yes, it is. If you look up "thermocouple" in Wikipedia, you will find a very detailed explanation of how and why they work.
Why is current in field winding of rotating electrical machines always dc?
Because with DC stationary field w.r.t. rotor can be easily created,and permanent pole can be created.
Why pole star remains stationery while earth is rotating?
Because the "pole star" is aptly named due to being located at Earth's pole. The pole is the axial point where Earth is rotating so anything located at the pole will appear as though it is stationary.
What prevailing wind patterns occur because the rotating earth deflects the wind?
they form by combining temperature and pressure!
Why is induction motor called as rotating transformer?
it may be because rotating transformer also have one winding turns while the other remains stationary.because the one that was stationary is the one that accepts signals and the one that was turning is the one who converts he signal into current and distribute it to the motors engine
Which kind of sensor could be used to control the temperatures inside a fridge?
the sensor used to control the temperature inside a fridge is, thermocouple because, its more accurate than a thermistate.
How do you do you use stationary in sentence?
Stationary is used as an adjective, because it describes a noun. The planets are not stationary.
Why does the water temperature have to be higher on conveyor dishwashers than enclosed stationary dishwashers?
Because an enclosed dish-washer retains heat better than a 'tunnel' dishwasher.
Why earth is considered as an inertial frame of reference although it is rotating?
Because we're rotating with it
Why is a nebula rotating?
Because the star that blew it off of itself was rotating. Conservation of rotational momentum.
Why is the SUN stationary?
It is not stationary, it is in orbit with the planets that orbit it (bi-orbital), however because it is so much bigger it does not move so far.Nothing is stationary; absolutely nothing.
