Displacement sensor advantages: depending on the location of the absolute analog signal can be easily integrated in a variety of environments, small space is also a word.
Displacement sensors are used to detect piston position at pneumatic and hydraulic jaws / cylinders, to monitor machine movement, penetrate housing wall / protective cover
Displacement sensor A potentiometer displacement sensor that converts a mechanical displacement into a resistor or voltage output in a linear or arbitrary function by means of a potentiometer element. Ordinary linear potentiometers and circular potentiometers can be used as linear displacement and angular displacement sensors, respectively. However, the potentiometer designed to achieve the purpose of measuring the displacement requires a definite relationship between the displacement change and the resistance change. The movable brush of the potentiometer displacement sensor is connected with the measured object. The displacement of the object causes the resistance of the movable end of the potentiometer to change. The change in resistance reflects the magnitude of the displacement, and the increase or decrease in resistance indicates the direction of the displacement. The displacement sensor usually passes the supply voltage on the potentiometer to convert the resistance change into a voltage output. Wirewound potentiometer because of its brush movement resistance to turn resistance for the ladder changes, the output characteristics are also stepped. If this displacement sensor is used as a displacement feedback element in the servo system, an excessive step voltage causes the system to oscillate. So the potentiometer in the production should be minimized the resistance of each turn. Another major drawback of the displacement sensor potentiometer sensor is ease of wear. Displacement sensor its advantages are: simple structure, the output signal, easy to use, low prices
