LVDT displacement sensors have a plunger
which moves freely in the sensor housing. The
plunger is joined to the object by a thread to
transfer the movement of the measurement
object. The measurement process in the sen-
sor takes place without contact and is there-
fore wear-free. The displacement sensors are
mainly used to measure and monitor move-
ments, displacements, positions, strokes, de-
flections, dislocations, etc. in vehicles, machi-
nes and systems.
The high sensor resolution is limited only by
the noise in the sensor electronics. A further
advantage of the symmetrically constructed
sensors in the LVDT series is the zero point
stability of the systems. The sensors are
supplied with an excitation frequency of 1 to
5 kHz depending on the measuring range
and an excitation amplitude of 2.5 to 5 V eff.
Matched sensor electronics are available in
this respect.
With appropriate setting possibilities for
the excitation frequency and amplitude, the
sensors can also be operated with alternative
electronics.
