The following steps are recommended to reduce the risk of
component failure due to electrostatic discharge.
Ship and store circuit boards in anti-static bags. If an antistatic bag is not available, wrap the board in aluminum foil.
Do not place boards on foam packing materials.
Use a grounding wrist strap when installing and removing
circuit boards. A grounded workstation is recommended.
Handle circuit boards only by the edges. Do not touch
components or connector pins.
Make sure that all electrical connections are completely
made and none are partial or floating. Ground all equipment to a good, earth ground.
2.3
Before You Begin
2.3.1 Site Preparation
Each R82 Radar transmitter is built to match the specific
physical specifications of the required installation. Make
sure the antenna connection is correct for the threaded or
flanged mounting on the vessel or tank where the transmitter will be placed. See Mounting, Section 2.4.
Make sure that the wiring between the power supply and
Radar transmitter are complete and correct for the type of
installation.
When installing the Radar transmitter in a general purpose

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 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 Antenna
•
•
•
•
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.
Antenna is being mounted in the optimal location. See following sections: Location, Beam Angle, Obstructions and
Nozzles for specific information.
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) of tank wall.

The various antenna designs exhibit different beam patterns.
Ideally, the beam pattern should illuminate the maximum
liquid surface with a minimum striking other objects in the
vessel including the tank wall. Use these drawings to determine the optimum installation location.
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 False Target
Rejection routine, all possible precautions should be taken
to minimize false target reflections with proper installation
and orientation.
2.4.1.4 Nozzles
Improper installation in a nozzle creates “ringing” which
will adversely affect measurement. Refer to Figure 9???. 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
a flange. The related distance as measured from the end of
the antenna varies depending on the antenna extension
chosen. See Figure ??.
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
exceed 2× the nozzle diameter. See Figure??????
NOTE: If the antenna is recessed in a nozzle it is mandatory that Echo
Rejection is run to eliminate any possibility of false reflections.
Maximum Recess (m) is 2 × Nozzle Diameter (d)

Figure X
R82 Mounted in Stillwell (Bridle)
•
•
The R82 can be mounted in a standpipe or stillwell but
certain considerations should be given:
Metal stillwells only: 2" (Sched 40 max.) to 4" (50–100 mm).
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 2.6.5.1, Item 34- PIPE I.D.
There will be some increased dielectric sensitivity; system
GAIN will be reduced when PIPE ID >0.
2.4.2 Installing the Transmitter
45°
Install the Transmitter with its integral antenna by threading
into the vessel. DO NOT OVERTIGHTHEN 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 transmitter can be
installed to allow for temporary submergence to 6 feet (1.8m):
- use TFE paste to seal conduit entries and antenna process
connection
- Do not overtighten housing cover; O-ring develops
water-tight seal without excessive tightening

The R82 transmitter utilizes a linearly polarized, microwave
beam that can be rotated to improve its performance. Proper
orientation can minimize unwanted target reflections, decrease
sidewall reflections (multipath) and maximize direct reflections from the liquid surface.
The internal launcher mechanism can be turned to optimize
performance. The launcher has index marks numbered
1–18 (representing 10–180 degrees). The Polarization
pattern is at 45 degrees to the transmitter display when
the mechanism is at the #9 position.

Ideally, the transmitter should be mounted half the radius
from the tank wall. In a typical vertical tank, the Launcher
should be adjusted so the polarization pattern is 45 degrees

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, Poor Echo

2.4.2.3 Poor Echo Strength
Poor signal quality has many potential causes. Following are
two initial areas for investigation.
Launcher Orientation: Initial launcher orientation is always
45 degrees (see Sections 2.4.1 & 2.4.2). In tall vessels and
when antenna is mounted close to the tank wall, improvement in signal quality 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
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.
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 ??). The directions for wiring the Radar transmitter
depend on the application:
• General Purpose or Non-incendive (Cl I, Div. 2)
• Intrinsically Safe
NOTE: For ATEX installation guidelines refer to bulletin BE 58-610.

2.5.1 General Purpose or Non-incendive (Cl I, Div. 2)
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. Replace cover to the wiring compartment of 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
Ground
)+(
Launcher
Adjustment
The R82 transmitter has a local user interface consisting of
a 2-line by 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 5 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 read 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. When the proper password is
entered, an exclamation point (!) appears as the last character of the first line of the display. 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.

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
Pulse
Pulse Burst
3.2.1 Pulse Burst Radar
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 5.8 or
26GHz 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.

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 (1000 ft/µs) 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 123 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. This information
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. Other Faults
can also be viewed using the UP/DOWN arrows. 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.
Other Warnings can also be viewed using the UP/DOWN
arrows. 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

arcs, and excessive temperatures in hazardous areas. Defined by
the IEC as Zone 1 environments (Ex e).
Non-hazardous Area An area where no volatile mixtures of
vapors/gas and oxygen will be found at any time. Also called
General Purpose Area.
Information (message) The lowest level in the hierarchy of diagnostic conditions providing operational factors that are not critical to measurement. Further information can be obtained by
viewing the Status or Diagnostic (Factory Menu) screens.
Non-Incendive A circuit in which any arc or thermal effect produced, under intended operating conditions of the equipment or
due to opening, shorting, or grounding of field wiring, is incapable, under specific test conditions, of igniting the flammable
gas, vapor, or dust-air mixture.
Intrinsically Safe Ground A very low resistance connecting to a
ground, in accordance with the National Electrical Code (NEC,
ANSI/NFPA 70 for FMRC), the Canadian Electrical Code
(CEC for CSA), or the local inspector.
Password A numerical value between 0 and 255 that protects
stored configuration data from unauthorized manipulation.
Intrinsic Safety A design or installation approach that limits the
amount of energy that enters a hazardous area to eliminate the
potential of creating an ignition source.
Level The present reading of the height of material in a vessel;
compliment of Distance.
LevlOfst Level Offset The distance above the tank bottom where
radar level measurement is impossible due to heating coils, baffles, angled or curved tank bottoms, etc. The mA output will
never read lower than the Level Offset value.
Linearity The worst case error calculated as a deviation from a

readings of the same process condition.
RFI Radio Frequency Interference Electrical noise that can have
an adverse affect on electrical circuits, particularly low-power
devices.
Safety Zone A user-defined area just below the Blocking
Distance where level measurement still has a high degree of reliability. Radar can develop ambiguous readings when the level
reaches the region of the antenna. An alarm can be annunciated
in this area for critical applications where reliable measurement is
a necessity for safety reasons.
Safety Zone Height The height of the region below the
Blocking Distance where an alarm will be annunciated upon
detection of liquid.
Safety Zone Fault An optional condition added, when necessary,
to ensure safe, reliable high-level readings in critical applications.
Choices are 3.6 mA, 22 mA, Latch 3.6 or Latch 22. If Latch 3.6
or Latch 22 are chosen, the loop current will remain in alarm
until it is cleared in SZ Latch menu screen.
TDR (Time Domain Reflectometry) Uses a waveguide to carry
EM energy to and from the surface of the media to measure distance; similar to conventional through-air Radar but much more
efficient. Also called Guided Wave Radar.
Trim 4/Trim 20 Built-in system capability to fine tune the
4 mA and 20 mA points so the transmitter output corresponds
exactly to user’s meter, DCS input, etc.
Trim Lvl Trim Level An offset parameter used to account for
various deviations in measurement. It is an offset value that can
force the transmitter to read the exact level reading.
Turbulnc Turbulence Agitation, or disturbance, of the liquid
level surface; greater the agitation, greater the scattering of the
radar signal (microwave energy).
Two Wire An electrical instrument design that uses one set of
wires to provide both the supply power and process measurement signal. The process measurement is achieved by varying the
current of the loop. Also called Loop Powered.
Units The engineering units used to measure level in the
system. The choices are in (inches) and cm (centimeters).
Warning (message) The second level in the hierarchy of
Diagnostics annunciating conditions that are not fatal but may
affect measurement. A message will occur on the main (rotating)
screen when a Warning is detected but will not affect output current. Further information can be obtained by viewing the Status
or Diagnostic screens.
Safety Zone Alarm Reset Use screen for clearing a Latched
Alarm set in Safety Zone Fault (above)
SnsrOfst Sensor Offset The distance (+ or -) between the
customer’s 100% reference point (tank top) and the Sensor
reference point (bottom of NPT thread, top of BSP thread
or face of flange).
Span The difference between the upper and lower limits of the
range.
Specific Gravity (SG) The ratio of the density of a material to
the density of water at the same conditions.
Sensitivity The amount of amplification applied to the Level
signal; a higher value aids in measuring low dielectric media; a
lower number assists in ignoring nearby objects.
Status The current state of the transmitter’s diagnostics; screen
updates every 10 seconds.
Targets Objects in the vessel that create reflections of the radar
signal (microwave energy).
Targ Rej Target Rejection The ability to ignore reflections from
objects in the vessel that are not the liquid level, i.e., false targets
(e.g. pipes, ladders, baffles).
Tank Ht Tank Height The tank measurement between the 0%
(tank bottom) and 100% (tank top).
Tank Top The 100% point in a vessel. Also considered for the
type of tank top; e.g. flat, dome, etc., which affects the development of multiple echoes during high level conditions. Multiple
echoes can appear as an invalid Level signal.

Service Policy
Return Material Procedure
Owners of Magnetrol/STI controls 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/STI 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/STI'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.
No claims for misapplication, labor, direct or consequential damage will be allowed.
