  • Absolute positioning on a budget
    When the Rock-Tenn paperboard mill in Aurora IL wanted to automate the. positioning and tensioning of the belts on its paperboard dryer conveyor. system, it took over a year to find a vendor capable of meeting the project. budget and specifications. Management wanted a robust, turnkey solution
  • Development of Battery-Free Multi-Rotation Absolute Encoder
    In recent years, greater accuracy and better reliability are demanded of motors, especially motors used in critical positioning applications. Such systems typically utilize encoder feedback with battery backup mounted on the motor, allowing it to perform closed loop control. However, since
  • Pros and Cons of Absolute vs. Incremental Rotary Encoders
    An incremental encoder simply generates pulses proportional to the position. The principle of the incremental measuring system is the scanning of a line pattern on a glass or plastic disc (see Image 1). An optoelectronic component converts the line pattern (transparent or not transparent
  • Telescope Positioning Using Tiltmeters
    Accurately positioning large and small telescopes. has always been a difficult problem. Jewell. Instruments precision tiltmeters provide a simple. and effective solution. Tiltmeters are unlike. conventional systems that measure telescope. position using rotary encoders coupled to the. telescope
  • 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
  • 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
  • Commutation of a BLDC Motor with Various Pole-Pairs Can Be Simplified By Using Absolute Encoder Feedback - White Paper (.pdf)
    fashion. Commutation of a brushless DC motor is dependent on the position of the rotor. It is essential to have feedback devices attached to the motor shaft to indicate the current rotor position to the controller. With various forms of feedback devices available, magnetic hall sensors and optical
  • How Does an Optical Encoder Work?
    The Optical Encoders typically consist of a rotating and a stationary member. The rotor is usually a metal, glass, or a plastic disc mounted on the encoder shaft. The disc has some kind of optical pattern, which is electronically decoded to generate position information. The rotor disc in absolute
  • Resolvers - The Feedback Problem-Solvers in Harsh Environments
    , and can be made radiation resistant. Resolvers provide absolute position information, and positional resolution is limited only by the electronics used to decode them. Unlike encoders, very long cable runs are possible with resolvers. Unfortunately, resolvers are also terrible! They require complex
  • A Novel Technique for Simultaneous Velocity and Interface Profile Measurements on Micro-Structured Surfaces
    be determined with a resolution of few tens of nanometers. The results for the liquid-solid interfaces are also compared to an additional detection method we devised to accurately determine the absolute position of the solid walls.
  • Tractor Steering
    cylinders. They offer convenient, protected mounting schemes and high reliability with a choice of data formats. These Temposonics sensors are absolute so that loss of power does not require re-homing or re-learning current position when power is restored. Though customarily supplied as rigid
  • Rotary Encoders: What They Are and How They Work
    Rotary encoders are electromechanical devices that detect an axle's absolute or relative rotational position. The resolution of the encoder determines the minimum detectable angular displacement.
  • Applying Encoders
    Encoders provide velocity, acceleration, direction,. and position feedback to motion systems. Two basic. types of feedback are absolute and incremental. Absolute. encoders report unique position information. at all locations and are unaffected by power loss. Incremental. encoders also deliver
  • Codesys PLC and Desulfurization System
    We are a country rich in coal and low in oil. Coal has always been in an absolute leading position in the composition of energy utilization. Even after many years of energy conservation and emission reduction work, the utilization of coal is still an astronomical figure.
  • Motion Platforms for Flight Simulators
    be achieved with the highest precision and responsiveness provided by Temposonics sensors. Another frequent requirement of this application is the ability to sense absolute velocity. Our sensors can provide both position and velocity within the same sensor.
  • Flow Solder Machines
    position feedback from highly accurate, continuous, absolute output. * Low temperature coefficient for stable output with varying operational temperature. * Superior EMI and noise immunity ensure trouble free operation in a wide range of applications. * Simultaneous multiple position sensing
