Rotary Potentiometers and Rheostats both make use of rotary motion to modify varying electrical characteristics. While they have some similarities, their application fields and working principles are distinct.

The 91A2A-B28-B18/B15L is a precision potentiometer. It is a finely calibrated piece of three-terminal equipment with a continuous rotatable shaft. It has an output signal between 0 and 100% that is a fraction of the input voltage. It is used for voltage, current, and frequency control in industrial and medical applications.

This potentiometer\'s working principle is based on a movable wiper which comes in direct contact with a resistive track. This resistive track has many fixed taps, each of which connects to a different portion of the track. The wiper, when rotated, alters the position of the wire connected to it, changing the equivalent resistance between the wiper and the track. This change in resistance causes the output voltage to change proportionately.

Rheostats, also known as variable resistors, are frequently used to vary the resistance in electrical circuits. The 91A2A-B28-B18/B15L is a two-terminal device which consists of a resistive track with a coil of wire around it. As the coil is rotated, the number of turns of the wire in contact with the track changes, thereby changing the resistance in the circuit. This type of rheostat is commonly used in inductance applications, such as controlling the speed of a motor or adjusting the brightness of a light.

The 91A2A-B28-B18/B15L rheostat has a continuous rotatable knob which can be used to adjust the resistance in the circuit. As the knob is rotated, the equivalent resistance changes, and this change in resistance causes the output voltage to change proportionately. This makes it ideal for controlling the current in a circuit, such as adjusting the brightness of a light or the speed of a motor.

In summary, both the 91A2A-B28-B18/B15L potentiometer and rheostat utilize rotary motion to modify varying electrical characteristics. The potentiometer has three terminals and is used for voltage, current, and frequency control in industrial and medical applications. The rheostat is a two-terminal device which is used to vary the resistance in an electrical circuit. The rotatable knobs on both devices are used to adjust the output voltage proportionately.
