  2. Galvanometer - Wikipedia

    en.wikipedia.org/wiki/Galvanometer

    An early D'Arsonval galvanometer showing magnet and rotating coil. A galvanometer is an electromechanical measuring instrument for electric current.Early galvanometers were uncalibrated, but improved versions, called ammeters, were calibrated and could measure the flow of current more precisely.

  3. Ballistic galvanometer - Wikipedia

    en.wikipedia.org/wiki/Ballistic_galvanometer

    A ballistic galvanometer is a type of sensitive galvanometer; commonly a mirror galvanometer. Unlike a current-measuring galvanometer, the moving part has a large moment of inertia, thus giving it a long oscillation period. It is really an integrator measuring the quantity of charge discharged through it. It can be either of the moving coil or ...

  4. Mirror galvanometer - Wikipedia

    en.wikipedia.org/wiki/Mirror_galvanometer

    Late 19th or early 20th century. This galvanometer was used at the transatlantic cable station, Halifax, NS, Canada Modern mirror galvanometer from Scanlab. A mirror galvanometer is an ammeter that indicates it has sensed an electric current by deflecting a light beam with a mirror. The beam of light projected on a scale acts as a long massless ...

  6. Chart recorder - Wikipedia

    en.wikipedia.org/wiki/Chart_recorder

    Many types of chart recorders use a galvanometer to drive the marking device. A light coil of wire suspended in the magnetic field of a permanent magnet deflects in proportion to the current through it; instead of the pointer and scale of a direct-reading meter, the recorder deflects a pen or other marking device.

  9. Vibration galvanometer - Wikipedia

    en.wikipedia.org/wiki/Vibration_galvanometer

    A vibration galvanometer is a type of mirror galvanometer, usually with a coil suspended in the gap of a magnet or with a permanent magnet suspended in the field of an electromagnet. The natural oscillation frequency of the moving parts is carefully tuned to a specific frequency; commonly 50 or 60 Hz. Higher frequencies up to 1 kHz are possible.
