  • Position Sensors and Position-Sensing Instruments
    sensors include rotary encoders and angular position sensors. Orientation position sensors include encoders, inertial gyros, and inclinometers.
  • How Does an Optical Encoder Work?
    the electronic signals are amplified and converted, they are then available for the evaluation of the position. In some applications the encoder shaft makes one revolution for one complete cycle of machine operation (angular rotation of a crankshaft in a punch press or rotary indexing table). Absolute
  • Advancements in Technology for Multiturn Encoders
    A single turn encoder is a transducer that precisely measures angular displacement over 360 degrees and assigns a value to each position. These values can be decimal, binary or grey code and the resolution of such systems is typically to 17 bit.
  • Optical Incremental and Absolute Rotary Encoders
    The purpose of an encoder is to act as a position feedback device as part of an integrated control system. The encoder is an electro-optomechanical device that attaches to a rotating shaft providing angular position information to a counter or controller. An optical encoder uses a code disk
  • Getting the right angle
    Angle encoders differ from standard duty rotary encoders in terms of accuracy as well as mechanical complexity and the number of counts per revolution. Typically, an angle encoder is probably best if an application needs positioning accuracy of 5 angular sec (0.001 ) or better and a minimum line
  • Eliminating sensors from closed-loopcontrol
    . Here's how encoderless systems compare with more traditional motor-control methods. To operate efficiently, a conventional flux-vector PWM drive needs to know the rotor flux angle inside an ac-induction motor. A pulse encoder typically supplies information about rotor speed and angular position
  • Finding the right sensor for linear displacement
    outage as before. Conversely, incremental sensors, such as encoders, cannot make meaningful measurements after power outages until they are rezeroed or returned to a "home" position. Although most of the sensing technologies discussed here can be used in rotary and angular-position sensing, we
  • Wedge drives precision elevator
    deflect the stage and change the angular relationship between the load and horizontal plane. Deflection increases as the load increases or the load's center of gravity moves farther away from the stage. The result is that vertical motion
