82A1A-B28-D15L

Rotary potentiometers, rheostats, and 82A1A-B28-D15L, are three electronic devices that are often confused with one another. All three are components used to measure or control electrical current and all have similar, yet distinct, uses.

Rotary Potentiometer

A rotary potentiometer is most often used as a variable resistor. Its main purpose is to measure the voltage difference at two points in an electric circuit. It is composed of a fixed resistor, called a rotor, and two sliding contactors, called a wiper. When the wiper slides back and forth along the rotor, it creates a unique voltage reading, which is used to measure the voltage difference at the two end points of the circuit.

Rheostat

A rheostat, like a rotary potentiometer, is also a type of variable resistor. However, the main purpose of a rheostat is to control the current flowing through a circuit, instead of just measuring it. This is done by varying the resistance within the circuit, which can be adjusted by turning a knob or sliding a wiper. Unlike a potentiometer, however, a rheostat does not have a fixed resistor, but rather the resistance is continuously adjustable.

82A1A-B28-D15L

82A1A-B28-D15L is a specific type of rotary potentiometer that is used to measure the voltage difference at two points in an electric circuit. It is a high-precision device, specially designed for use in devices such as sensors, automotive electronic control units and medical equipment. The 82A1A-B28-D15L is composed of a rotor and two sliding contactors. The rotor is a zero balance type, meaning it is pre-calibrated to provide a fixed voltage range throughout the range of the device. The contactors, on the other hand, are used to measure the exact voltage difference between the two end points of the circuit. This is done by sliding the contactors along the rotor, which varies the resistance and thus alters the voltage in the circuit.

In conclusion, all three components, rotary potentiometers, rheostats, and 82A1A-B28-D15L, are essential parts to electric circuits. They are all used to measure or control electrical currents, yet they have distinct uses that make them valuable components.
