  • Valve Position Sensing - Analog
    Position sensing is offered on all models of Acro Associate's pinch valves. Position sensing supplies electronic feedback on a valve's position (or state). This feedback confirms that a valve is in the state dictated by a control input. A key benefit to position sensing is that it provides
  • Valve Position Sensing - Digital
    Position sensing is offered on all models of Acro Associate's pinch valves. Position sensing supplies electronic feedback on a valve's position (or state). This feedback confirms that a valve is in the state dictated by a control input. A key benefit to position sensing is that it facilitates
  • True Position Measurement
    multiple measurement steps and mathematical calculations. Portable CMM technology can alleviate much of this work by allowing the user to fix the part in one spot, take several points to create an alignment of x- and y- axes, and measure the bore. Software is then able to determine the position
  • The third derivative of position is jerk
    . Like most students, I learned to use calculus by rote. This issue of our magazine is a special supplement on motion control, and where would motion control be without calculus? The most vivid recollection I have of college calculus is how it reveals the relationships between position, velocity
  • Position Sensor Technology Comparison
    Position feedback sensors for hydraulic. or pneumatic cylinders have used one of three. traditional technologies: magnetostrictive, variable. resistance, and variable inductance sensors. While other sensor technologies have occasionally. been used successfully in this application,. the focus
  • Bi-directional Incremental Position Display
    A system is needed which will track the position of a bi-directional linear-motion platform. and allow the user to select a home or zero position. The display should read in inches. and indicate the position of the platform at all times.
  • Magnetostrictive Position Transducers in Medical Applications
    Magnetostrictive position transducers are non-contact, absolute reading, and have essentially infinite resolution. The non-contact nature of this technology means that there are no rubbing or sliding parts to wear out, and assures an unlimited service life for the position transducer. High
  • Stepper Position Maintenance Mode (.pdf)
    Stepper motors are designed to offer an economical method of open-loop motion control. While easy-to-use, they are prone to skipping or stalling resulting in position loss. This application note discusses various options for handling stepper motor position error and presents new commands available
