    具体特征
  • Description

    Inductive displacement sensors of this series measure linear displacements and indirectly all mechanical values convertible into displacements by additional equipment (i.e. tension and compression forces, extension, torque, vibration). The sensor body equipped with a connector has an outer diameter of only
    8 mm and therefore is especially well suitable for the integration in dimensionally restricted structures.
    Typical application fields are displacement and extension measurements on
    ► Machines
    ► Servo systems
    ► Motor vehicles
    ► Test benches
    ► Production plants

    The cylindrical case made of stainless steel, houses a
    differential transformer (LVDT). It consists of a primary and two
    secondary coils with axially moveable core. A displacement of
    this core changes the magnetic induction of the coils. The IN-
    LINE carrier frequency amplifier converts the displacement
    into a direct proportional electrical DC voltage.
    The transducer is constructed as a probe at which within the
    measuring range a spring pushes the probe tip towards the
    measuring object. Bellows protect the mechanical guidance
    of the probe tip against pollution and splash water.
    The IN-LINE amplifier is integrated in the connector cable
    and adjusted specifically to the sensor. Both components
    form a unit while they can be separated for mounting
    purposes (miniature plug connection at the transducer). The
    use of not harmonized components may lead to increased
    measurement errors. For the IN-LINE amplifier version the
    sensor body is galvanically isolated from the excitation and
    from the measuring signal.
    Lateral forces decrease the durability.
