   Potentiometer displacement sensors: 

    The mechanicaldisplacement into a linear or any function of the resistance or voltage output and the potentiometer elements. General linear and circular potentiometer potentiometer can be used as a linear displacement and angular displacement sensor. However,designed to achieve the purpose of measuring displacementpotentiometer, requirements between the displacement variationand resistance variation has a definite relationship. Figure 1 thepotentiometer displacement sensors and the object to be measured is connected with the movable brush.

     Object displacement resistance change caused by mobile terminalpotentiometer. Variable resistance reflects the displacement value, increase or decrease the resistance that the displacementdirection. Usually pass on the potentiometer to the supply voltage,to the resistance change is converted to a voltage output. Wire wound potentiometer wiper is moved due to its resistance to change turn resistance ladder, the ladder shaped output characteristic was also found. If this displacement sensor used in the servo system position feedback device, is too large a step voltage will cause system oscillation. Therefore, the production of the potentiometer should be to minimize the resistance of each turn. Another major drawback potentiometer type sensor is easy to wear. Its advantages are: simple structure, large signal output,convenient use, low price.

     Hall displacement sensor: principle of measurement is to maintain its hall element (see semiconductor magnetic sensingelement) of the excitation current constant, and the moving in a uniform magnetic field gradient, then move the displacement is proportional to the output of the Huo Er potential. The greater the magnetic field gradient, the higher the sensitivity; gradient moreuniform, the relationship between the Hall potential and displacement is more close to linear. 

     Figure 2 is the threegeneration gradient magnetic field system: the linear range of a system is narrow, the displacement Z=0, the Hall potential = 0; B system when Z<2 mm with good linear, Z=0, Hall electric potential =0; the sensitivity of C system, the measurement range is less than 1 mm. Figure N, S positive, negative pole respectively. Hall displacement sensor of small inertia, high frequency response,reliable work, long service life, so commonly used in a variety ofnon electricity and then converted into the displacementmeasurement.

    Photoelectric displacement sensor: it according to the displacement or geometric size of the measured object blockingoptical flux measurement of object. Characterized by a non-contact measurement, and can continuously measure.Photoelectric displacement sensor used in the continuousmeasurement of wire diameter or the strip edge position control system for edge position sensor.
