  • 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.
  • 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
  • Criteria for the Selection of the Proper Distance Sensor Technology
    is the deviation from an ideal linear function (straight line). It is mostly shown in percent of the measurement range final value (Full scale). Response time is the time a sensor requires to rise from 10% to 90% of the maximum signal level. For sensors with digital signal processing this time
  • Application Note: Velocity Measurements
    How do I measure the velocity of a hydraulic cylinder using a LVDT signal?. The customer is testing aircraft hydraulic cylinders. He is plotting the throw of the cylinder using an LVDT (Linear Variable Displacement Transformer) which outputs a voltage proportional to the displacement along
  • Resulting Position Error After Mulitpoint Linear Error Compensation with the LIDA 400 (.pdf)
    The accuracy of incremental linear encoders is comprised mainly of the position error over larger distance intervals and the position error within one signal period. With the LIDA 400, the position error over the measuring length is measured in a comparative measurement with a calibrated reference
  • 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
  • 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
  • Gauging Depth of Field in Your Imaging System
    . The depth of field specification is further complicated by a type of keystoning aberration that often occurs. This result can dramatically affect linear measurements and therefore render depth of field unusable. In this article we will take a closer look at depth of field calculations and compare
  • MICRO: Product Technology News
    times per nozzle, can be adjusted via the PLC terminal. Service areas can be accessed from the front, sides, and back of the system. All wetted materials are fireproof and acetone-proof. An analog absolute-linear-position sensor using proprietary magnetoinductive technology provides accurate
