  • Current Sensor Info.
    Open Loop Operating Principle In a hall effect-based current sensor, the magnetic flux, proportional tothe primary current, is concentrated in gapped magnetic corecontaining the hall effect device (Fig. 1). The primary current ismeasured without electrical contact with the primary circuit
  • Sensor Sense: Hall-effect current sensors
    sensor completes the magnetic path and helps concentrate the magnetic field through the sensor. The sensor produces an output voltage directly related to the strength of the magnetic field generated by the current flowing through the shunt. Many such sensors operate from a single 5-Vdc supply so
  • Evaluating AC Current Sensor Options for Power Delivery Systems (.pdf)
    Current sensors are essential components in many power deAC Current Sensor Block Diagramlivery systems such as ac-dc and isolated dc-dc switch mode power supplies (SMPS), motor control and electronic lighting. As power supply manufacturers strive to increase the power density and reliability
  • Linear Position and Displacement Measurement With Capacitive and Eddy-Current Sensors
    Virtually all capacitive and eddy-current sensor applications are fundamentally a measure of displacement (position change) of an object. This Application Note details the specifics of making such a measurement and what is required to make reliable measurements in micro and nano displacement
  • ELECTRICAL RUNOUT USING AN EDDY-CURRENT SENSOR FOR ROUNDNESS MEASUREMENTS
    Electrical runout is a commonly used term in the condition monitoring industry. It refers to the apparent displacement of a rotating shaft measured with inductive (eddy current) sensors caused by variations in the material electrical and magnetic properties
  • First SOIC8-Packaged Hall-Effect Current Sensor With Integrated Current Path Introduced
    The newest current sensor family from Allegro MicroSystems, Inc., the ACS704, is the first SOIC8-packaged Hall-effect current sensor with the current path integrated into the package for greater sensitivity and accuracy. The newest current sensor family from , the ACS704, is the first
  • Comparing Capacitive and Eddy-Current Sensors
    Noncontact sensors using capacitive and eddy-current technologies each represent a unique blend of advantages and disadvantages for a variety of applications. This comparison of the two technologies' strengths will help you select the best technology for your application.
  • Force Measurement With Capacitive and Eddy-Current Sensors
    Force is often measured as a deflection of an object of known stiffness. Noncontact methods are ideal for measuring the force-related deflection as they do not load the object with additional mass or affect its stiffness. These noncontact sensors are very precise and are best used in applications
  • Inmold Eddy Current Sensor Detects Core Shift
    Sometimes, the best things in life come unexpectedly. For Ken Gabrys, mold engineering manager at Sage Products, stumbling across a magazine article was the best thing that could have happened to him and the 25-year-old molding company for which he works.
  • Eddy Current Profiles Parts
    current characteristic of a part with respect to the position variable. In a profiling application, either a dual- or single-element eddy current sensor is passed over the surface of the part and its position, with respect to that part is measured with a linear displacement device such as a linear
