IMPORTANT SAFETY INSTRUCTIONS –
read this before use.
Workplace hazards:
This equipment will be installed close to rail and road
traffic, which is hazardous workplace. It is very important
to investigate for regulations in respect of risk assessment,
formal personal education demands, authorization etc.
before installation of the equipment.

1.2 Unpacking and Parts Identification
Your X20SR Speed Radar has been shipped in protective packaging.
Please verify the package content with the following list:
INFRA X20SR Speed Radar Unit
Please report any damage or shortage immediately to Sigicom.

2General description
The INFRA X20SR Speed Radar is designed for speed
measurements of different types of vehicles. Speeds up to 250 km/h
can be measured with 2 km/h resolution, both moving towards and
away from the unit.
The X20SR uses a high quality Doppler radar module, working in
the K-band (24.15GHz ISM Band). Dual channel techniques and
advanced signal processing makes it possible to distinguish between
movements toward and away from the unit, as well as filter out false
moving objects.
The X20SR continuously calculates speeds in both directions. At the
end of each interval it selects the direction seen the largest reflected
signal level to represent the interval. Movements toward the unit are
presented as positive values and movements away from the unit are
presented as negative values.
All quantities that are measured by your system are synchronized,
and can be viewed in any of the INFRA presentation systems.
The X20SR Speed Radar shall be connected to the INFRA Field
Monitoring System by any of the available INFRA Sensor Cables,
which:
Supplies the X20SR with electrical power
Handles the communication with the Datalogger, which is
the main unit in the INFRA Field Monitoring System.
Within INFRA Field Monitoring System it is possible to measure a
number of other quantities simultaneously with the speed
measurements, for example:
vibration (geophone) in one direction
vibration (geophone) in three directions
sound level
air blast
dust concentration

3Design features
3.1 Quantities
Speed: Maximum speed with direction indicated as its sign measured
in kilometers per hour [km/h]. Calculation, which is over the selected
interval time, is made inside the X20SR.
3.2 Display devices
Your X20SR Speed Radar shall be connected to the INFRA Field
Monitoring System. Preferably use INFRA Net to display your
recorded measurements.
It is also possible to view the latest saved value and live values in the
Datalogger display.

4Configuration and operation
4.1 Mounting
Mounting the X20SR unit correctly is very critical for achieving
acceptable results, or even results at all. The unit needs to be firmly
mounted (when measuring), especially if measuring close to the rail.
Preferably use a stable pole combined with proper mounting details,
as shown below for mounting of the unit.
The unit has a RAM Mount ® 1.5” RAM Ball Base attached to its
back side. RAM Mount products is widely available over the world.
See http://www.rammount.com/partners.
Example: http://www.ram-mount.se/ram-202u-225.html , often with
parts in stock.

See http://www.rammount.com/part/RAM-202U-225 as an entry for
suitable mounting accessories, or
http://www.rammount.com/components/1.5?query=1.5 for all 1.5”
accessories.
For rail vehicle measurements it is recommended to position the
radar 5-10 meters from the rail and direct the radar sideways so that
it aims to (the center of) the rail 40-70 meters away. The radar
should be approximately 1.5 meter above the rail level and
horizontally aligned with good precision, using a spirit-level is
recommended.
For road vehicle measurements the height level above the road is
recommended to be 0.6 –0.8 meter to be able to catch all standard
sized cars.

4.2 Lobe
The measurement lobe is narrow, this means that the radar will have
to be very exactly pointing to the object of measurement. The lobe
has different width depending on its alignment. It is recommended to
mount the radar so that the lobe is wide in the horizontal plane for
measurements on fast vehicles.
The lobe widths are indicated on the case of the unit.
Lobe
Blue
12 deg (±6 deg from center line)
Red
24 deg (±12 deg from center line)

4.3 Range
The range differs depending on a number of factors, keeping within
70 meters from objects have been successful in field tests.
4.4 Angle error correction
Depending on how the radar is mounted there might be need for
certain correction on the measured speed due to the angle in which
the radar measures. If following the recommendations in this
manaual, the correction due to radar position and direction will be
minimal.
Radar setup, v can be either positive or negative.

* not recommended distance
** measurement errors larger than 3.5% due to radar placement
The radar placement will be a problem if the distance dis long and
distance Lis short, a potential problem could appear if being unable
to setup the radar with a short distance dto the rail. As seen in table
above, this is simply fixed by directing the radar further down the
rail (increase L). But then the total range of the radar might become
an issue instead.
In such a situation, a rule of thumbs could be to assure that
70m > 𝐿 > 4𝑑
in order to secure measurements with less than 3.5% error due to
radar placement.
4.5 Mounting check
It is recommended (if possible) to check the setup functionality after
mounting. This is easiest done by waiting for the passage of a
vehicle, then read “LAST value” values from the logger during or
directly after the passage. 5 seconds interval time is recommended
for the test.
By continuously pressing “F2” the last interval value will show in
the display, until it is replaced by a new one. If a reasonable value is
shown when a vehicle is passing by then the unit is set up properly.

4.6 Parameters
The parameters described below are normally set using the user
interface of the Datalogger. However, some parameters are also
possible to set in INFRA Net (Remote control).
4.6.1 Standards
X20SR Speed Radar has only one standard
1
.
S01 (SR km/h):
Top speed during interval measured in kilometers per hour [km/h], the
resolution is 2 km/h.
4.6.2 Interval time
The interval time is how often the measured speed value is
registered. The minimum interval time is 5s.
4.6.3 Threshold levels
No threshold levels can be set for the INFRA X20SR unit.
4.6.4 Customer string
The customer string is a four character string that can be changed.
The default string is “SR “.
1
The word standard means for X20SR the measured quantity and its unit.

4.7 Quick start
1. Connect your X20SR Speed Radar with your INFRA
Datalogger (Master, Mini or Micro) by using any of the
available INFRA Sensor Cables.
2. Start the Datalogger and wait for initialization process to be
