The models which are currently available
are the result of research which has im-
proved the whole range, incorporating a
new concept of the internal mechanism
being submerged in an oil-bath box, and
the microprocessor-based logic.
LE 101:
In this model the pendulum unit and the
analog VA110 read-out unit are connected
by means of a cable. The analog display
allows the choice of 3 different measuring
scales. It is possible to connect two levels
in the differential mode. Collection of data
can be made through a serial port (optio-
nal) to be connected to the PC.
LE 201:
This intermediate model has a micropro-
cessor-based logic, and it shows the error
by means of an integrated digital display,
with the possibility to choose the unit of
measurement in µm/m, seconds or µrad
during calibration. All of the procedures
are achieved by means of only three but-
tons, with the possibility to use the unit
with the LE 301 model in differential
mode.
LE 301:
This is the most complete model, also
with microprocessor-based logic, and
an integrated digital read-out unit, with
the possibility to store the data and then
transfer them to the PC with a connection
cable. The Wplan Microplan software will
elaborate the measurements taken with
the electronic level, in order to present a
plot of the measured surface.
This level can work in combination with
another LE 301 level, or with an LE 201
level, in differential mode.
LE 050:
This model allows a very easy use for any
operator.
The galvanometer placed on the front
panel shows the error according to five
different measuring scales.
It is made up of an alluminium structu-
re with black granite base, incorporating
an analog display and a wooden handle.
The internal mechanism is submerged
in an oil-bath box. The level is powered
by rechargeable batteries, with test but-
ton for battery status.
LE 051:
This traditional model has been concei-
ved for fast and easy use.
The galvanometer placed on the front pa-
nel shows the error according to five diffe-
rent measuring scales.
It is made up of a stabilised cast iron
structure, incorporating an analog and
digital display, a wooden handle and a
spirit level. The internal mechanism is
submerged in an oil-bath box. The level is
powered by a rechargeable battery, and it
has a button which indicates the status of
battery charge.
LE 401:
The latest model of the Microplan level
series works by means of radio transmis-
sion of the inclination values.
It has a sensor unit (LE401) and a sepa-
rate digital read-out unit (VD410). It has
several functions, which can be achieved
by means of a simple but complete in-
ternal menu. The internal mechanism is
submerged in an oil-bath box, and it can
read up to 10 different sensor units by
means of a single VD410 read-out unit,
in a range of action of 30 metres.
