  • Current Sensor Info.
    supply polarity is respected to prevent damage to internal circuity. Non-linearity due to magnetic core saturation can occur at primary currents in excess of 2X the nominal rated current. Hall effect based current sensors are affected by static and dynamic electric and magnetic field; usetwisted
  • Position Sensors and Position-Sensing Instruments
    Position sensors include wide range of sensors, switches and technologies that are used to determine the placement, speed or movement, direction, and location of a given target. Linear position devices include cable extension, capacitive, eddy current, fiber optic, Hall effect, inductive, magneto
  • Magnetic Sensing
    in salt spray or sand and dust environments, and under differential pressures up to 20,000 psi. Eddy-current sensors detect ferrous and nonferrous metals. A high-frequency magnetic field induces eddy currents in metal targets. The eddy currents generally change the

  • Magnetic Term Glossary
    by an external magnetizing field to create a useful magnet which has a net magnetic moment. In un-magnetized material the domains are un-oriented and cancel each other out. In this condition there is no net external field. Eddy currents, are circulating electrical currents that are induced in electrically
