Table 2: Comparison of several popular types of linear position sensors. b. Lower non-linearity is better, and means the difference between a straight line and the. output. c
  • Understanding Digital Potentiometers Resistor Variations
    ). The characterization graphs shown in Figure 10. through Figure 13 had Terminal B to VSS and Terminal. A to VDD. Within a voltage range, the change in resistance will be. linear relative to the device voltage. At some point as. the voltage decreases, the resistive characteristics of. the switches

  • No contact means no headaches in position transducing
    for the noncontacting potentiometer shows the coupling capacitance , and the stray ground capacitance, , are then summed by the integrating amplifier. The amplifier output voltage, , is proportional to the position of the probe. Noncontacting potentiometers typically are more linear than contacting types
