Radar applications are characterized by three basic conditions;
Dielectric, Distance (measuring range) and Disturbances
(turbulence, foam, false targets, multiple reflections and rate
of change).
2.3.3.1 Maximum Distance
The chart at left shows the maximum measuring range
(Distance) based on fundamental conditions of Dielectric,
Distance and Turbulence. Maximum distance is calculated
as Tank Height + Sensor Offset (see page 20). It is measured
from the Sensor Reference Point (bottom of NPT thread,
top of BSP thread or face of a flange).
2.3.3.2 Minimum Distance
If the liquid level is allowed onto the antenna, noise and
media build-up drastically decrease reliable measurement.
Liquid should not be allowed closer than 15 inches
(380 mm) from the bottom of the antenna mounting
threads (or face of hygienic flange). The distance from the
end of the antenna varies depending on antenna chosen.
See Figure 8.

2.3.3.3 Problematic Applications; GWR Alternative
•
•
•
•
58-610 Model R82 Radar Transmitter
Some application concerns can be problematic for Radar.
For these, Guided Wave Radar is recommended:
Extremely low dielectric media (εr<2.0)
Very weak reflections from the liquid surface, particularly
during turbulence, can cause poor performance.
Tanks heavily cluttered with false targets (mixers, pumps,
ladders, pipes, etc.)
During times of very low liquid levels of low dielectric
media, the metal tank bottom may be detected deteriorating performance.
11
• Foam can either absorb or reflect the microwave energy
depending upon the depth, dielectric, density and wall
thickness of the bubbles. Due to typical variations in the
amount (depth) of foam, it is impossible to quantify performance. It may be possible to receive most, some or
none of the transmitted energy.
• Extremely high liquid levels (Overflow) conditions when
liquid very near the antenna (above the Blocking Distance)
can cause erroneous readings and measurement failure.

2.4 Mounting
The R82 Radar transmitter can be mounted to a vessel
using a variety of process connections. Generally, either a
threaded or flanged connection is used.
2.4.1 Installing the Transmitter
•
•
•
•
Before installing, make sure:
Process temperature, pressure, dielectric, turbulence and
distance are within the antenna specifications for the
installation.
End of antenna is protected from bending or breaking.
Insulating material is not placed around any part of the
Radar transmitter including the antenna flange.
Transmitter is being mounted in the optimal location. See
following sections: Location, Beam Angle, Obstructions
and Nozzles for specific information.
Figure 10
2.4.1.1 Location
Ideally, the Radar transmitter should be mounted providing an unobstructed signal path to the liquid surface where
it should illuminate (with microwave energy) the largest,
possible surface area. See Section 2.4.1.2, Beam Angle.
Unavoidable obstacles will produce reflections that must
be minimized during field configuration. See Section
2.6.5.1, Target Rejection. Mount in a location equal to 1⁄2
the radius of tank top. Do not mount in center of vessel
nor closer than 10" (25 cm) from the tank wall.

the vessel including the tank wall.
Figure 11

58-610 Model R82 Radar Transmitter
2.4.1.3 Obstructions
Almost any object that falls within the beam pattern will
cause reflections that may be misinterpreted as a false liquid
level. Although Model R82 has a powerful Echo Rejection
routine, all possible precautions should be taken to minimize false target reflections with proper installation and
orientation. See Figure 12.
2.4.1.4 Nozzles
Improper installation in a nozzle creates “ringing” which
will adversely affect measurement. Two Antenna extension
lengths are offered to allow the R82 transmitter to work
reliably in a variety of nozzles.
The Minimum Blocking Distance of 15" (380 mm) is
always measured from the bottom of the threads or face of
the flange. The related distance as measured from the end of
the antenna varies depending on the antenna extension
chosen. See Figure 13.
Figure 12
The narrow beam width of the 26 GHz, R82 does allow
mounting so that the antenna can be recessed inside the
nozzle. Optimally, the recessed dimension should never
× the nozzle diameter. See Figure 13
exceed 2×
Avoiding Obstructions
NOTE: If the antenna is recessed in a nozzle it is mandatory that Echo
Rejection is run to eliminate any possibility of false reflections.

Launcher Adjustment in
#11 Position (default)
The R82 can be mounted in a stillwell but certain considerations should be given:
Metal stillwells only: 2" (50 mm) Sched 40 max.
Diameter must be consistent throughout length; no reducers.
Stillwell length must cover complete range of measurement
(i.e., liquid must be in stillwell).
Welds should be smooth.
Vents: holes <0.125" diameter, slots <0.125" width.
If an isolation valve is used, it must be a full port ball valve
with an I.D. equal to the pipe diameter.
Bridles/Bypass Installations: The launcher should be rotated
90° from process connections.
Configuration must include an entry for PIPE I.D.
See Section 2.6.6.2, Item 34- PIPE I.D.
2.4.2 Installing the Transmitter
Install the Transmitter with its integral antenna by threading
into the vessel. DO NOT OVERTIGHTEN as this may
cause damage to the plastic threads.
• Do not place insulating material around any part of the
radar transmitter including the antenna flange.
• Installation for NEMA 6P/IP 68: the Lexan® housing can
be installed to allow for temporary submergence to
6.5 ft. (2m) for 24 hours:
- use TFE paste to seal conduit entries or IP 68
cable glands
- Do not overtighten plastic housing cover; O-ring
develops water-tight seal without excessive tightening
2.4.2.1 Orientation
The R82 transmitter utilizes a linearly polarized, microwave
beam that can be rotated to improve its performance.
Proper orientation can minimize unwanted reflections,
decrease sidewall reflections (multipath) and maximize
direct reflections from the liquid surface.

from the tank wall. In a typical vertical tank, the Launcher
should be adjusted so the polarization pattern is parallel to a
line tangent to the nearest tank wall. See Figure 16.
Rotate the internal Launcher adjustment to achieve the
correct Polarization position. Remember each notch on the
adjustment wheel is 10 degrees of rotation. See Figure 17.
90 degrees: Rotate Launcher
Mechanism CW 9 notches
A transmitter mounted within 10" (25 cm) of a tank wall
may demand orientation adjustments to limit multipath
and optimize performance. See Section 2.4.2.3,

Internal Launcher Adjustment
58-610 Model R82 Radar Transmitter
For horizontal cylindrical vessels, aim beam down the long
axis of the vessel. Do not optimize the Echo Strength at one
level in the vessel.
2.4.2.3 Poor Echo Strength
Poor Echo Strength has many potential causes. Following
are two initial areas for investigation.
Launcher Orientation: Initial launcher orientation is always
parallel to tangent of the tank circumference (see Sections
2.4.2.1 & 2.4.2.2). In tall vessels and when antenna is
mounted close to the tank wall, improvement in Echo
Strength may be attained by rotating the launcher to
90 degrees.
Signal Loss: If the Level signal is lost repeatedly at a specific
point in the vessel, it is usually a symptom that multipath
(side-wall reflections) are causing cancellation by returning
to the transmitter exactly 180° out of phase with the Level
signal. Utilize the following procedure:
• Go to transmitter screen #5 which shows both Level and
Echo Strength.
• Bring the Level up (or down) to the exact point where the
signal is repeatedly lost. Monitor the Echo Strength this
point is being approached. The Echo Strength will degrade
to a low point before it begins to increase.
• At the poorest Echo Strength slowly rotate the launcher
1–2 notches. Allow the unit to stabilize for approximately
one minute. Repeat this process until the Echo Strength
is optimized.

Wiring
Wiring between the power supply and the Radar transmitter
should be made using 18–22 AWG shielded twisted pair
instrument cable. Within the transmitter enclosure, connections are made to the terminal strip and the ground
connections. Trim excess wiring to minimize clutter, noise
issues and allow access to Launcher adjustment. See
Figure 19. The directions for wiring the Radar transmitter
depend on the application:
• General Purpose or Non-incendive (Cl I, Div. 2)
• Intrinsically Safe
2.5.1 General Purpose or Non-incendive (Cl I, Div. 2)
Figure 19
Wiring the Transmitter
Caution: The R82 Radar transmitter
operates at voltages of 16–36 VDC (GP)
and 16-28.6 VDC (IS). Higher voltage will
damage the transmitter.
NOTES:
• If sufficient supply voltage is suspect,
use the R82 Low Voltage check
(Section 2.6.6.1, #37: Test 4-20 Loop).
• For ATEX installation guidelines refer to
bulletin BE 58-610.
A general purpose installation does not have flammable
media present. Areas rated non-incendive (Cl I, Div. 2) have
flammable media present only under abnormal conditions.
No special electrical connections are required. If flammable
media is contained in the vessel, the transmitter must be
installed per Cl I, Div. 1 standards of area classification.
To install General Purpose or Non-incendive wiring:
1. Remove the cover to the wiring compartment of the transmitter. Install the conduit plug in the unused opening.
2. Install a conduit fitting and pull the supply wires.
3. Connect shield to an earth ground at power supply and
leave floating at the transmitter.
4. Connect an earth ground wire to the nearest green ground
screw per local electrical code (not shown in illustration).
5. Connect the positive supply wire to the (+) terminal and
the negative supply wire to the (-) terminal.
6. Seal conduit to prevent ingress of moisture.
7. Replace cover of the transmiter.
2.5.2 Intrinsically Safe
An intrinsically safe (IS) installation potentially has flammable media present. An approved IS barrier must be
installed in the non-hazardous (safe) area.

To install Intrinsically Safe wiring:
Make sure the IS barrier is properly installed in the safe
area (refer to local plant or facility procedures). Complete
the wiring from the barrier to the Radar transmitter.
Remove the cover of the transmitter. Install the conduit
plug in the unused opening.
Install a conduit fitting and pull the supply wires.
Connect shield to an earth ground at power supply and
leave floating at the transmitter.

Configuring the Transmitter
The Radar transmitter comes factory-calibrated and can be
configured in minutes for specific applications.
Before configuring the transmitter, collect the operating
parameters information. Then, power-up the transmitter
on the bench and follow through the step-by-step procedures for the menu-driven transmitter display. Information
on configuring the transmitter using a HART communicator is given in Configuration Using HART (Section 2.7).
2.6.1 Operating Parameters
Some key information is needed to configure the Radar
transmitter. If necessary, complete the configuration information table in Section 1.1.2.
2.6.2 Setting Up for Shop Configuration
The Radar transmitter can be configured at a test bench by
connecting a 24 VDC power supply directly to the transmitter terminals. The connections are illustrated in the
accompanying diagrams. An optional digital multimeter is
shown if current measurements are desired.
When using a HART communicator for configuration, a
minimum 250 Ω line load resistance is required. See the
HART communicator manual for more information.

2.6.3 Transmitter Display and Keypad
The R82 transmitter has a local user interface consisting of
a 2-line × 16-character liquid-crystal display (LCD) and
4-push-button keypad. All transmitter measurement data
and configuration information is shown in the LCD.
The transmitter default display is the measurement screen.
It cycles every 2 seconds to display *STATUS*, *LEVEL*,
*ECHO STRENGTH*, *%OUTPUT*, *LOOP CURRENT* and *LOCAL TAG* information. The transmitter
defaults to this display after 5 minutes if no keystrokes are
sensed. You can also access each of these screens individually. The display will not return to the default screen if left
in one of these screens. For example, the device can be left
to display only LEVEL indefinitely if left in this screen.

2.6.5 Password Protection (Default = 0)
The Radar transmitter is password protected to restrict
access to certain portions of the menu structure that affect
the operation of the system. The password can be changed
to any numerical value up to 255. The password is required
whenever configuration values are changed.
The default password installed in the transmitter at the
factory is 0 (password disabled). The last step in the configuration menu provides the option to enter a new password.
If 0 is entered as a password, the transmitter is no longer
password protected and any value in the menu can be
altered (except diagnostic values) without entering a confirming password.
NOTE: If the password is not known, the menu item New Password
(Section 2.6.6.1, item #39) displays an encrypted value representing the present password. Call the factory with this
encrypted value to determine the actual password.

6.
The Model 705 is available with a 20-point custom strapping table. Up to 20 pairs of Level—Volume points can be
entered to linearize the 4–20 mA output for odd-shaped
vessels.
Ensure that “Level and Volume” is selected as the
Measurement Type (parameter 9 in table 2.6.6.1).
Ensure that the correct Level Units and Volume Units are
chosen (parameters 10 and 11 in table 2.6.6.1).
Scroll down to the StrapTbl (parameter 12 in table 2.6.6.1),
press enter. Pt01Lvl is displayed.
Press Enter, then enter the desired level for Point 1 in the
strapping table and press enter.
Enter corresponding volume for Point 1 in the strapping
table (shown as Pt01Vol on the LCD) and then press enter.
Repeat steps 4 and 5 for remaining points.
NOTES:
1. All twenty strapping table points do not have to be used. All
unused points should be left at zero.
2. Strapping table point values can be entered or changed in
any order.
3. All strapping table points must be monotonic and sequential.
In other words, each point must be larger than the one
before. If a non-monotonic entry is made, the strapping
length will stop at that entry.

provide a communication link to the Model R82 transmitter.
When connected to the control loop, the same system measurement readings shown on the transmitter are shown on
the communicator. In addition, the communicator can be
used to configure the transmitter.
To confirm HART hand-held communications, attach unit
per Section 2.7.1. If communicator reads GENERIC on
first two lines, the HART hand-held does not contain the
current DDs (device description) for the Model R82 Radar
transmitter. Contact your local HART Service Center and
specify a Magnetrol Model R82 device descriptor.

A HART communicator can be operated from a remote
location by connecting it to a remote junction or by connecting it directly to the terminal block in the electronics
housing of the ModelR82 transmitter.
HART uses the Bell 202 frequency shift key technique of
high-frequency digital signals. It operates on the 4–20 mA
loop and requires 250 Ω load resistance. A typical connection between a communicator and the Model R82 transmitter is illustrated.
2.7.2 Display Menu
A typical communicator display is an 8-line by 21-character
LCD. When connected, the top line of each menu displays
the model (Model R82) and its tag number or address.
Usually the bottom line of each menu is reserved for software-defined function keys (F1–F4). For detailed operating
information, refer to the instruction manual provided with
the HART communicator.
The Model R82 transmitter online menu trees are shown in
the following illustration. Open the menu by pressing the
alphanumeric key 1, Device Setup, to display the secondlevel menu.

3.0 Reference Information
This section presents an overview of the operation of the
Model R82 Radar Level Transmitter, information on troubleshooting, common problems, listings of agency
approvals, lists of replacement and recommended spare
parts, and detailed physical, functional and performance
specifications.
3.1 Description
The Model R82 is a two-wire, 24 VDC level transmitter
based on the concept of pulse burst radar operating at
26GHz. The electronics are mounted in a metal or plastic
housing with an innovative, internal launcher orientation
mechanism.
3.2 Theory of Operation
3.2.1 Pulse Burst Radar
Pulse
Pulse Burst
The Model R82 is a top-mounted, downward-looking pulse
burst radar operating at 26 GHz. Unlike true pulse devices
that transmit a single, sharp (fast rise-time) waveform of
wide-band energy, the R82 emits short bursts of 26 GHz
energy and measures the transit time of the signal reflected
off the liquid surface. Distance is calculated utilizing the
equation Distance = C × Transit time/2, then developing
the Level value by factoring in Tank Height and Sensor
Offset information. The exact reference point for distance
and level calculations is the Sensor Reference Point—bottom
of an NPT thread, top of a BSP thread or face of a flange.

58-610 Model R82 Radar Transmitter
The exact level measurement is extracted from false echo
reflections and other background noise via the use of sophisticated signal processing. The new R82 circuitry is extremely
energy efficient so no duty cycling is necessary to accomplish effective measurement. For this reason, the R82 can
track high rates of change that were heretofore impossible
with existing loop-powered radar transmitters.

3.2.2 Equivalent Time Sampling
ETS, or Equivalent Time Sampling, is used to measure the
high speed, low power EM (electromagnetic) energy. ETS is
a critical key in the application of Radar to vessel level
measurement technology. The high speed electromagnetic
energy (1 ft/nS) is difficult to measure over short distances
and at the resolution required in the process industry. ETS
captures the EM signals in real time (nanoseconds) and
reconstructs them in equivalent time (milliseconds), which
is much easier to measure with today’s technology.
ETS is accomplished by scanning the tank to collect thousands of samples. The round-trip event on a 40-foot (12.3m)
tank takes only 82 nanoseconds in real time. After it is
reconstructed in equivalent time it measures 135 milliseconds.

Troubleshooting
The Model R82 transmitter is designed and engineered for
trouble-free operation over a wide range of operating
conditions. Common transmitter problems are discussed
in terms of their symptoms and recommended corrective
actions.
WARNING! Explosion hazard. Do not remove covers unless power
has been switched off or the area is known to be nonhazardous.
Use of the included PACTware™ PC program is highly
recommended and invaluable for troubleshooting and
advanced calibration. A HART RS232 or USB modem
(purchased separately) is required. See Magnetrol
PACTware™ bulletin 59-101.

3.3.2 Error Messages
The Model R82 Radar transmitter utilizes a 3-section
hierarchy for reporting diagnostic conditions: FAULTS,
WARNINGS, and INFORMATION. FAULTS and
WARNINGS will be shown in the Home screen when the
message is active. A chronological listing of messages can be
viewed in the HISTORY screen.
FAULT: The highest level in the hierarchy of diagnostics
annunciating a defect or failure in circuitry or software
that precludes reliable measurement. The current (mA)
value unit defaults to 3.6, 22, or HOLD and the Home
screen will freeze showing the highest priority Fault.
A chronological listing of messages can be viewed in the
HISTORY screen.
WARNING (MESSAGE): The second level in the hierarchy of Diagnostics annunciating conditions that are not
fatal but may affect measurement. The highest priority
Warning will be placed on the main (rotating) screen when
a Warning is detected but will not affect output current.
A chronological listing of messages can be viewed in the
HISTORY screen.
INFORMATION (MESSAGE): The lowest level in the
hierarchy of diagnostic conditions providing operational
factors that are not critical to measurement. A chronological
listing of messages can be viewed in the HISTORY screen

Service Policy
Return Material Procedure
Owners of Magnetrol may request the return of a control
or any part of a control for complete rebuilding or replacement. They will be rebuilt or replaced promptly. Controls
returned under our service policy must be returned by
Prepaid transportation. Magnetrol will repair or replace
the control at no cost to the purchaser (or owner) other
than transportation if:
So that we may efficiently process any materials that are
returned, it is essential that a “Return Material
Authorization” (RMA) number be obtained from the
factory, prior to the material's return. This is available
through Magnetrol’s local representative or by contacting
the factory. Please supply the following information:
1. Returned within the warranty period; and
2. The factory inspection finds the cause of the claim to
be covered under the warranty.
If the trouble is the result of conditions beyond our control; or, is NOT covered by the warranty, there will be
charges for labor and the parts required to rebuild or
replace the equipment.
In some cases it may be expedient to ship replacement
parts; or, in extreme cases a complete new control, to
replace the original equipment before it is returned. If this
is desired, notify the factory of both the model and serial
numbers of the control to be replaced. In such cases, credit for the materials returned will be determined on the
basis of the applicability of our warranty.
