The electronic level is a high-precision
instrument for testing the inclination and
slope relative to a horizontal line or any
given angle.
The readings are expressed by means of
a digital or an analog numeric display in
µm/m (micron for meter), in seconds of
arc, or in µrad (microradians), accor-
ding to choice, and the error values are
displayed very quickly.
The instrument works on a pendulum
principle. A pendulum always hangs ver-
tically, thus allowing measurement of the
displacement relative to the horizontal
base, by means of an inductive position
transducer.
The innovation that applies to all MICRO-
PLAN levels is that the mechanical parts
are contained in a sealed oil-bath, which
provides very good protection against
shocks, for instance during transport or
handling.
Electronic levels are currently used in the
following applications:
> Recording errors of straightness, flat-
ness and parallelism.
> Mounting and levelling of machinery.
> Testing for inclination, twist and flexion
in civil engineering.
MICROPLAN GROUP
offers a wide range
of models to meet the various needs
of customers: With an analog or digital
display, with the possibility to use in
differential mode together with another
level, with various base lengths, sepa-
rate read-out unit, etc.
The models which are currently available
are the following:
> LE 101
equipped with the VA110 read-out unit
> LE 201
with an integrated digital read-out unit
> LE 301
with a remote control
> LE 401
equipped with the VD410 read-out unit
> LE 050
with analog display
> LE 051
with a digital/analog display
Every ‘LE’ model can be used with the
‘WPLAN’ software, to calculate the
flatness, straightness and parallelism of
a surface, for easy data processing, ar-
chiving and printing, as well as a graphic
print-out of the surface or line under test.
The demo version of the ‘WPLAN’
software can be downloaded from our
website:

the ‘on-line support’ area.
