Potentiometer is a resistance element with three terminals, and its resistance value can be adjusted according to a certain change law. Potentiometers usually consist of resistors and movable brushes. When the brush moves along the resistor, the resistance value or voltage related to the displacement is obtained at the output end. Potentiometers can be used as both three-terminal elements and two-terminal elements. The latter can be regarded as a variable resistor.
Principle of angular displacement sensor: It is a model of displacement sensor and adopts non-contact patented design. Compared with other traditional angular displacement measuring instruments such as synchronous analyzer and potentiometer, the long-term reliability is effectively improved. Its unique design can still ensure the measurement accuracy without using movable parts such as slip rings, blades, contact cursors and brushes.
