Revision 1 SLN 700 SmartLine NCR Level Transmitter User’s Manual Page 1
1 Introduction
1.1 Overview
The SLN 700 SmartLine 80 GHz Non-Contact Radar transmitter is an electronic instrument
designed to measure levels of liquid and solid materials. Non-Contact Radar (NCR) transmitters
use Frequency Modulated Continuous Wave (FMCW) radar signals that are reflected by the
material to be measured. The difference in frequency between the received and transmitted
signal is directly proportional to the distance to the liquid and can be measured with high
precision. Its small beam angle and small antenna size makes it easy to install. In comparison to
other level measurement technologies, NCR provides a highly-accurate, cost-effective, reliable
measurement in applications where Guided Wave Radar (GWR) are not suitable.
1.2 Transmitter Models
The SLN 700 SmartLine 80 GHz NCR transmitter is available as a part of the family of
SLN700L models for liquid and SLN700S for solid applications. The pressure and temperature
range is -40 to 200°C/-1 to 40 bar for both, and each model is available with a range of flange or
threaded antenna, lens diameters, process connection, and accessories to suit most applications.
1.3 Transmitter Components
Overview of components
As shown in Figure 1-1, the transmitter consists of:
•Electronics housing containing the core measurement module and optional display
module
•Process connection
•RF antenna
Figure 1-1 Components of the Level transmitter

Page 2 SLN 700 SmartLine NCR Level Transmitter User’s Manual Revision 1
Electronics
The Electronics consists of 2 distinct modules; core measurement electronics module and an
optional display module. Both are replaceable in the field.
To make changes to the transmitter setup or configuration without the use of an external device
such as a handheld or PC, an optional 4-Button interface is available.
The Optional Display module has the following features. (needs to be updated)
•Echo stem plot for checking measurement accuracy
•Standard and custom engineering units
•Diagnostic alerts and diagnostic messaging
•English and Chinese language options
Process Connector
The 80 GHz non-contact radar transmitter has 3 different series of products and associated

1.6 Transmitter Model Number Description
The model number is comprised from a number of selections and options that can be specified
when ordering the transmitter. It includes a basic transmitter type such as SLN720 (standard
temperature, standard pressure) followed by a maximum of nine additional character strings that
can be selected from a corresponding Table in the Model Selection Guide (MSG).
The basic model number structure is shown in Figure 1-3.
Figure 1-3: Standard SLN 700 Model Number
For a more complete description of the various configuration items and options, refer to the SLN
700 Product Specification (34-SL-03-06) and Model Selection Guide (34-SL-16-20).
1.7 Safety Certification Information
SLN transmitter models are available for use in Intrinsic Safe locations, including IECEx,
ATEX, and NEPSI approvals. See SLN 700 Product Specification (34-SL-03-06) or SLN 700
Quick Start Guide (34-SL-25-14) for details and other approvals.

2 Radar Level Measurement
2.1 Overview
This chapter describes the theory of operation of the transmitter and discusses how
measurements are affected by tank and process conditions.
2.2 Theory of Operation
The fundamental principle of operation is level measurement through the reflection of frequency
modulated radar waves (FMCW technique). The antenna emits a continuous wave of radiation
near 80 GHz whose frequency linearly increases in time in a saw tooth pattern. When the return
pulse is detected by the same antenna, the processing electronics use a Fourier Transform
technique to calculate the difference between the frequency of the generated and reflected signal.
This difference is proportional to the distance of reflection.

Page 6 SLN 700 SmartLine NCR Level Transmitter User’s Manual Revision 1
3 Mounting
Due to the finite beam angle and resulting transmission cone, there should be no obstacles in the area
radiated by the transmitted microwave beam from the lower edge of the antenna to the material surface to
be measured. Therefore, it is necessary to avoid these facilities in the tank during installation. These
include ladders, limit switches, heating equipment, supports, etc. If necessary, some of the obstacles can
be removed from the measurement using background subtraction ("Virtual Echo Learning"). In addition,
please note that the microwave beam should not intersect with tank fluid in or out flows. Please also note
that the highest material level should not enter the near range (see Figure 3-1), the instrument should be
kept at a certain distance from the wall of tank wall and the transmitting antenna should be perpendicular
to the measured material surface as much as possible. The instruments installed in a hazardous classified
area shall follow the local national installation regulations.
The reference plane for measurement is the sealing surface of threads or flanges.
1. Near distance
2. Far distance
3. Distance at which sensor reads 100% level (or current)
4. Distance at which sensor reads 0 % level (or current)
Figure 3-1: Graphical illustration

Revision 1 SLN 700 SmartLine NCR Level Transmitter User’s Manual Page 7
Moisture-proof
For instruments that are installed outside, in a wet environment, and cooling or heating tanks, the
cable gland must be tightened. The cable, at the cable gland entry, must be bent downward to
prevent moisture as shown in Figure 3-2.
Figure 3-2: Moisture-proof diagram

Page 8 SLN 700 SmartLine NCR Level Transmitter User’s Manual Revision 1
Installation position
During the installation, please note that the instrument should be kept minimal distance to tank
wall from the vessel wall. For different antenna, please refer to Table 3-1.
However, the instrument must not under any circumstances be mounted closer than 200mm to
the vessel wall or values calculated from Table 3-1.
1. Reference plane
2. Center of the vessel or symmetry axis

For the conical vessel with a flat tank top, the best installation position of instrument is the top
center of the vessel, which ensures that the bottom of the container is measured.

Page 10 SLN 700 SmartLine NCR Level Transmitter User’s Manual Revision 1
Nozzle installations
In the case of a material with good reflection properties (high dielectric constant, DK), the
sensor may be mounted on a nozzle. The background subtraction ("virtual echo learning")
feature can further reduce false echoes from nozzle openings.
Table 3-2 shows detail of the size limitations of the nozzle.

Correct and incorrect Installation position
1. Correct
2. Incorrect: Instruments are installed in the arched or round top of the tank, which will result in
multiple echoes. This should be avoided as much as possible during the installation.
Figure 3-6: Correct and incorrect installation position
1. Incorrect Instruments should not be installed above the fluid in-take , in order to ensure that the
dialectic surface will be detected rather than the charging material flow
2. Correct
Figure 3-7: Correct and incorrect installation position
Note: sun-shading and rain proof measures should be adopted for the outdoor
installationInstallation of reflecting plate
If there are barriers in the tank, the reflecting plate can be installed to reflect the echo wave away
from the sensor. If necessary, "virtual echo learning" can be turned on.

Page 12 SLN 700 SmartLine NCR Level Transmitter User’s Manual Revision 1
Figure 3-8: Installation of reflecting plate
Installations with Agitation
If there are agitators in the tank, the instrument should be installed as far away from these as
possible. Once the installation is completed, the “"virtual echo learning" should be carried out
while the agitators are running. This will eliminate the influence of false echo generated by
mixing blades. If foam or wave is generated due to agitation, then the customer should consider
a guided wave radar sensor such as the Honeywell SLG-700 series.
