  • Finding the right sensor for linear displacement
    on the physical attributes as they relate to installation. And researchers probably choose sensors based on technical performance. The most frequently used electromechanical linear position and displacement sensors can be divided into six basic technologies: resistive, capacitive, inductive, magnetic, time
  • One Sensor, Multiple Targets
    A single linear sensor monitors multiple positions along its axis. A single linear sensor monitors 20 positions. Time to read 20 positions matches that of a single position. Strokes over 5,000 mm, accuracy of +-20 mm, and resolutions of 1 mm. Magnetostrictive Sensors For Bottle Filling
  • Linear-Measuring System Saves Space
    mm not accurate enough for machinetool applications. Direct-measurement, linear-displacement systems are a step up. In these devices, a sensor reads position from a scale along the entire length of the linear axis. Combined with numericaldisplacement interpolation, the units deliver positioning
  • Sensors Reference Guide: One Sensor, Multiple Targets
    A single linear sensor monitors multiple positions along its axis. It is often advantageous to have a single sensor monitor more than one feedback parameter. This is now possible in the case of a linear-position sensor that can track as many as 20 moving positions along its axis. The sensor uses
  • Medical Device Link .
    Spotlight on Sensors and Transducers A transducer incorporates a flexible cable, a spring-loaded spool, and a potentiometer to detect and measure linear position. With a measurement range of 4.75, 12.5, 25, or 50 in., the SP1 string pot is suited for restricted space installations. Most common
  • Measuring the long haul
    . But where stainless tape is punched with a coded pattern and read by an optical sensor, the new method makes use of an extruded aluminum profile containing buried magnets. A special Hall-effect sensor detects the magnets and determines absolute position. These position multiplexer encoders, or Pomux
  • Electrohydraulic Actuators
    the sensor interact with the magnetic field and return a sonic pulse. Distance can be determined by measuring the transmission/reception time interval. Positioning accuracy is 0.001 to 0.003 in. Another way to accurately control position is to hydraulically amplify the motion of a stepping motor
