5 Design, system overview and function

The dual sonic sensor
DUAS-1000
is a distance measurement sensor and
operates using ultrasonic technology.
The temperature of the value measured by the Dual-Sonic Sensor is
compensated by means of a reference measurement versus a bracket with a
defined distance parallel to the actual distance measurement.
The prop. laser receiver
LS-3000
is a distance measurement sensor which
operates with all conventional rotary lasers such as e.g. red light transmitters
(helium, neon) and infrared transmitters.
It is used for square construction, etc. and is equipped with a reception range
of 29 cm.
Power masts are only used in combination with laser receivers.
Power Mast
ETM-900
significantly increases the reception range of a laser
receiver, as the sensor can be guided over the lifting cylinder's entire
adjustment range.
One further advantage offered by the power mast is the fact that the user can
very quickly and comfortably position the laser receiver in the transmitter's
laser beam.
If both sides of the vehicle are to be regulated using laser receivers, a power
mast must be installed for each side to consistently exploit the above
mentioned advantages.
