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.
