PRODUCT DESCRIPTION
The SDI-RADAR-LX-80 radar- based level sensor was developed specifically for continuous water
level monitoring in rivers, lakes and sea unlike other radar level sensors that were initially developed
for industrial applications and later adjusted to work in environmental monitoring applications. It
comes in three versions: 8 meter, 15 meter and 30 meter each with a 10m cable

The radar operates in the W-band (between 77 and 81 GHz), which provides high accuracy and
allows multiple radars to operate close to each other without mutual interference. Unlike
ultrasound level sensors, it is not affected by changes in air temperature and density.
The SDI-RADAR-LX80 is quickly and easily mounted to a pole above a water surface using the
supplied mounting bracket (part number 21135) and requires minimum maintenance once installed.
Mounting instructions are contained in Chapter 4.
For ease of reference, this manual shall refer to all models as the LX-80 throughout the document.
2.1 CHANGING UNITS
The following measurement units are supported:
• Millimeters
•
Centimeters
• Meters
•
Feet
• Inches
It is possible to change the measurement unit of the LX-80 using any of the supported
communication protocols. When changing the unit of measurement, special care must be taken to
ensure all related parameter values are also changed as the device will now use the selected
measurement unit for every measurement and every measurement parameter.
IMPORTANT: If measurement units are changed, other parameters which depend
on the measurement unit (such as active zone parameters) should also be changed
to the new unit
