  • Application: Linear Distance Measurement Sensor (.pdf)
    Often these measuring devices used a walking device having a wheel that translates circular motion into a linear distance. These devices used a mechanical means to establish the distance. These mechanical devices did not always prove reliable and would often fail at the most inappropriate times.
  • Criteria for the Selection of the Proper Distance Sensor Technology
    An efficient selection of the proper sensor technology for distance measurement becomes more and more important. Continuously increasing requirements to machine capacity and reduced budgets requires a lot of experience especially as regards the selection of the proper measurement process to be able
  • Coating Thickness Measurement: The Fundamentals
    . The magnetic induction method measures non-magnetic coatings over ferrous substrates and magnetic coatings over non-magnetic substrates. The process is direct, in that a probe is placed on the part to be measured. When the probe is positioned, the linear distance between the probe tip that contacts
  • Sizing and Applying Magnetostrictive Linear Position Sensors
    temperature, pressure, flow, force, or position, for example. The type of measurement and the sensor technology will dictate the set of parameters which are important in specifying and sizing the appropriate sensor. Linear-position sensors measure absolute distance along a motion axis
  • Motion and Manipulation Glossary
    Linear off-axis error introduced through amplification of tilt and wobble with a long moment arm. This type of error occurs when the point under measurement is at a relatively long distance from the axis of motion.
  • Glossary of Terms
    Abbe Error Linear off-axis error introduced through amplification of tilt and wobble with a long moment arm. This type of error occurs when the point under measurement is at a relatively long distance from the axis of motion, typically greater than 12 inch
  • Application Note: Velocity Measurements
    the cylinders 8" stroke. A velocity measurement is best done through the use of the differential equation: V = dS/dT or Velocity = a change in distance divided by a change in time.
  • Measure Angles on Rotating Systems with High Resolution
    A common approach to measuring distance or angle in a rotating system is by using an incremental encoder or resolver. The majority of industrial applications, such as machines or drives, are dominated by optical encoder -either with incremental or absolute output of the distance or angle. However
