Instrumentation And Control:

As temperature changes the resistance of certain metals will also change.   This features is the basis for the operation of an RTD.

 DESCRIBE the construction of a basic RTD involving:

a. Major component arrangement

b. Materials used

 EXPLAIN how RTD resistance varies for the subsequent:

a. An increase in temperature

b. A decrease in temperature

EXPLAIN how an RTD gives an output representative of the measured temperature.
