LVDT sensor
An important advantage of the LVP
measuring technique lies in the short length
of the installed sensor. This difference in
lengths becomes clear in a direct
comparison with an LVDT sensor.

Voice coil actuators are used for positioning
with small displacements, with a high
dynamic response, high repeatability and
positioning accuracy as well as with strong
accelerations. In conjunction with a servo
system the voice coil actuator and the
displacement sensor are operated in a
closed circuit. These systems are used in
applications in the optical industry, such as
for optical scanning, focusing, tracking and
stabilizing. Through the use of the sensor
the optical beam path and the mechanical
system can be set up on one axis. The
optical path is combined with the line of
center of gravity for the motor and the
measurement object.
This produces a simpler mechanical
construction, higher stability and a smaller
installation space.

The sensor system LVP-xx-P-LP-I/D is used
as a testing system for the verification and
inspection of the functionality of the system
in electro-hydraulic servo valves.
The modular sensor construction facilitates
a fast and simple adaptation to the specific
application for use in large-scale produc-
tion. The sensor and electronic system can
be constructed as one unit or with a sensor
cable. The LVP principle enables matching
of the measurement ranges in a span from
±1 to ±5 mm by simply changing the target
length.
The sensor element is mounted in the
pressure-free space and is protected by a
pressure pipe. The acquisition of the target
position occurs through the pressure pipe.
