  • Magnetic Field Sensors as Speed Monitors
    Magnetic field sensors are generally based on the magneto-resistive or Hall-principle. Compared to optical speed sensors, resolvers and precision potentiometers, magnetic field sensors do not contain movable parts, such as shafts, bearings, code disks or slip rings. An aspect allowing them
  • Operating Principles for Magnetic Sensors
    Magnetic proximity sensors are actuated by the presence of a permanent magnet. Their operating principle is based on the use of reed con-tacts, whose thin plates are hermetically sealed in a glass bulb with inert gas. The presences of a magnetic field makes the thin plates flex and touch each other
  • Ten Easy Things to Do with Magnetic Sensors
    The measurement of magnetic fields for their own sake is a relatively uncommon goal outside the laboratory. It is more typical (in industrial, consumer, and automotive applications, for example) to see a magnetic field used as an indicator of some other phenomenon such as position or speed. Over
  • Common Mode Field Rejection in Coreless Hall-Effect Current Sensor ICs
    , and high accuracy over temperature. This technology also has near zero magnetic hysteresis, as there is no core used for concentrating the field. However, the disadvantage of not using a core is that the sensor IC is susceptible to stray magnetic fields. With a core, stray magnetic fields are shunted
  • AN1162 - Sensorless Field Oriented Control (FOC) of an AC Induction Motor (ACIM)
    " for a complete list of related the best solution. The term "sensorless" does not documentation available from Microchip. represent the lack of sensors entirely, but the fact that in comparison with other drives from the same category Control Strategy of field oriented control, it denotes
  • Design and Development of Medical Electronic Instrumentation
    stabilization. network, electrostatic discharge simulators, conducted-disturbance generator,. magnetic field generator, and wideband transmitter for susceptibility testing. In Chapter 5 we present the new breed of "smart " sensors that can be used to detect. physiological signals with minimal design
  • Part 2-Flow Energy Management Applications-Installation Tips & Tricks
    can install the insertion vortex flow meter in large steam pipes with no process shutdown. Watch video to get additional hot tap installation tips for the InnovaMass 241i insertion vortex flow meter. 3. Tips for ultrasonic flow meter installation.
