EMF (E''electromotive Force'') is another term for Volts, hence the E in electronic formulas and EMF is measured with a volt meter. A potentiometer is not a meter at all, it is a variable resistor
The potentiometer is a position tranducer. It forms a resistance divider, proportional to position.

A: A potentiometer is a manual device to change the resistance A thermistor changes as a function of environment temperature
Yes, but you need a circuit (a PLC may be of help) to convert the potentiometer output (say 0 V to Vmax) into angles. A conventional potentiometer (linear) powered by a constant voltage power supply will work for angles from 0 to 90 degrees, since the voltage you get will be proportional to the angle sinus, starting from zero up to Vmax @ 90 degrees. For angles from 0 to 180 degrees (or -90... 0... +90 degrees) it will be easier with two power supplies connected in series taking the middle point as zero (Volts). Positive voltages from the potentiometer cursor against zero will be obtained for positive angles and negative voltages for negative angles, but you might need a 360 degrees or multiturn potentiometer. There is the basic idea, the rest is yours...
what type of transducer potentiometer
The balance point is where a scale can balance equally.
A potentiometer is a variable resistor used in electronics.
A dual potentiometer is nothing but a potentiometer which has TWO channels.. Like two INs and two OUTs on the same unit.
Sensitivity of potentiometer: A potentiometer is said to be more sensitive, if it measures a small potential difference more accurately.

The null method is used in measuring the unknown EMF of batteries. The method is about using a potentiometer circuit with the battery of a known and then an unknown EMF connected to it one after the other and locating, in each case, the position of the 'null point'; the point on the potentiometer circuit where the current through the battery is zero.
