Displacement sensors with external controller
induSENSOR LVDT
- Proven LVDT technology
- Measuring ranges ± 1 … ± 25 mm
- Extremely accurate also under
difficult ambient conditions
- Long-term stability
- Wear-free measurement
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 movements, dis-
placements, positions, strokes, deflections,
dislocations, etc. in vehicles, machines 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.
