level sensor series
SUPERPROX® SM902 SERIES
3-107
Up to 8-Meter
Range Dual-
Level Sensing
The world’s leading ultrasonic
technology now makes possible
discrete level control in vessels,
tanks, hoppers, bins and
reservoirs, covering object
distances a few inches from the
sensor to as far away as 26 feet.
Depending on the model
selected and material being
detected, the SUPERPROX®
Model SM902 series of “smart”
dual-level sensors offers sensing
ranges of 1 m (39"), 2 m (79"),
and a long-range 8 m (26'), with
the shortest deadbands in the
sensing industry of 51 mm (2"),
120 mm (4.7"), and 203 mm (8"),
respectively.
In addition to range selection,
the sensors can be factory
configured for a specific level-
control function, output type,
response time and functionality.
Using these selections, an ideal
solution can be found for such
operations as: starting and
stopping a pump and opening
and closing a valve. Others
include controlling either loop
levels or tension on web pro-
cessing lines relative to two set
level control limit points.
Packaged for mounting
convenience in a threaded,
30 mm housing, 60% smaller
than other level sensors with
equal functionality, these dual-
level sensors are easily installed,
without positioning limitations, in
covers and other hard-to-mount
areas. All models are equipped
with a pushbutton to set the
sensor’s near and far limits of the
sensing “window.” When it is
impractical to use the push-
button for setting long-range
limits, an optional, hand-held,
setup/display accessory is
available. All limits are stored in
nonvolatile memory and thus are
retained if power is removed
from the sensor.
Unlike other sensing technologies,
these sensors are capable of detecting
all materials, liquid, granular and solid,
regardless of color, shape and composi-
tion, transparent or opaque, including
powder, food products, grains, chemi-
cals, pharmaceuticals, oils, plastics and
objects that change colors. The sensors
are available in either ULTEM® plastic or
SS303 stainless steel housings which
are fully encapsulated to withstand
shock and vibration. Both are sealed to
withstand dusty, dirty, clean-in-place,
noncondensing humidity, high-pressure
washdown environments, and they are
virtually unaffected by changing light
conditions, colors and noise. With
housings that meet NEMA 4X and IP67
industry standards, the sensors resist
most acids, bases and oils, including
most food products. All the sensors in
this model series are CE certified.
Additionally, the Model SM902 series
sensors offer dependable operation and
compatible integration with most
programmable logic controllers.
1-meter and 2-meter-
range models
In the Model Reference Guide, the
standard 1-meter-range models are
identified as the Model SM902A-1 and
SM952A-1 series sensors, and the 2-
meter-range models are identified as the
Model SM902A-4 and SM952A-4 series
sensors. Respectively, these models
provide for dual-level sensing from 50.8
mm to 1 m (2 to 39") and 120 mm to
2 m (4.7 to 79"). The length of the
connector model, excluding the connec-
tor/cable assembly, is just 96 mm (3.78"),
thus adding to the mounting conve-
nience. These sensors operate on a
sonic frequency of 200 kHz and are
available with response times as fast as
150 ms. The FDA approved silicone
rubber transducer face, while used to
couple the ultrasonic energy to the air,
is also resistant to most acids, bases,
oils and food products. Selected sensors
in this model series are DeviceNet
capable.
For dual-level-control sensing applica-
tions that involve severe, corrosive-type
environments, the Model SM902A-7STS
and SM952A-7STS sensors have an
SS303 stainless steel housing with an
SS304 stainless steel-faced transducer.
These models, with a sensing range of
120 mm to 1 m (4.7 to 39"), provide
reliable operation in the detection of
certain strong chemicals and corrosive
materials, and where caustic cleaning
solutions are used in washdowns of
machinery and equipment in close
proximity to the sensor. For out-of-doors,
dual-level-control sensing applications,
where cold weather is a factor, these
corrosion-resistant models provide
reliable operation in temperatures as
low as -10° C (14° F).
Nonlevel-control applications ideally
suited for these sensors within the 1-
and 2-meter ranges include: container
accumulation detection on mass
conveyors and controlling either loop
positions or tension on web processing
lines relative to two set control limits.
8-meter,
long-range models
No other discrete, level-control sensor
on the market has as short a deadband,
as long a sensing range, and is housed
in as small a package as the Model
SM902A-8 and Model SM952A-8 series
of long-range, ultrasonic, dual-level
sensors. As indicated in the Model
Reference Guide, these 30 mm sensors
detect objects over a sensing range of
just 203 mm (8") to 8 m (26'). The
116.31 mm (4.579") length of the cable
model, a fraction of the size of other
long-range sensors, ensures easy
installation. The sensors operate on a
sonic frequency of 75 kHz with a
standard response time of 1 second with
other response times available. The
transducer face of the fully encapsulated
sensor is made of epoxy which, in
addition to coupling the ultrasonic
energy to the air, allows the sensor to
perform in a wide range of harsh
environments including those involving
most acids, bases and oils.
Applications for these long-range,
dual-level sensors can be found in
almost every industry or business when
reliable detection within the range of 8
meters (26 feet) is required. By virtue of
the 75 kHz sonic frequency, the sensor’s
wide, 20-degree beam is especially
effective in sensing the levels of various
types of liquids, solids and granules as
close as 203 mm (8") from the sensor’s
face. These applications include the
processing of food and beverage
products and pharmaceuticals, as well
as the treatment of water and sewage.
In the sensing of dry materials, such as
grains and powders, the long-range,
dual-level sensors offer an efficient
alternative to certain limit switch devices
which can be prone to frequent mainte-
nance problems and unreliable
operation.
In applications where high sound
absorption conditions may exist in the
material being detected, and either the
one- or two-meter range model sensor
becomes unreliable because of lost
energy, the more powerful long-range
SM902 can provide the solution when
used within the sensing ranges of either
one or two meters.
Temperature compensation allows
these long-range sensors to operate
reliably in outdoor applications in
temperatures ranging from
-20° to 60° C
(-4° to 140° F).
Operation
The SUPERPROX® Model SM902
series sensor, operating on 12 to 24 VDC
regulated power, is a self-contained,
pulse-echo, dual-level, sensing device
that monitors and controls most nonhaz-
ardous material levels within the speci-
fied sensing ranges. With extremely
short deadbands, the sensors are
capable of detecting levels of liquids,
solids and powders as high as 51 mm
(2") from the sensor face.
Before operation, a pushbutton
“teach” function is used to set the
sensing window limits. The near and
far limits of a desired sensing window
can be set anywhere within the sensing
range and may be set to encompass
the full sensing range or be as small as
desired. A double press of the SETUP
pushbutton, makes possible the setting
of a default window anywhere within the
sensing range.
Functionality in the operation of the
30 mm, long-range sensors includes the
capability to be configured for various
NPN and PNP, Normally Open, Normally
Closed or Complementary output modes
for: pump-in latch or pump-out, with and
without alarm or setpoint, and dual
alarm/dual setpoint operations. A loss-
of-echo feature can be selected to hold
the output in the event of a loss-of-echo
condition.
During setup and operation, a
multicolor LED indicates the limits setup
and operational modes; a red LED
illuminates when the output is in an
active (On) state.
3-108
How does it work?
During setup and operation, these
SM902 Series sensors continually and
accurately measure the elapsed time of
every pulse echo reception between
each pulse transmission. The transmitted
pulse begins a time clock to register the
elapsed times for the received pulse
echoes. Given the elapsed time, the
sensor software calculates the distance
traveled out to the object or surface and
back to the sensor, using the formula, D
= TVs/2, where D = Distance from the
sensor to the object; T = Elapsed time
between the pulse transmission and its
echo receptions; V = the Velocity of
sound, approximately 1100 feet per
second.
During operation, the calculated
distance (D) between the sensor and the
object (e.g., level) is compared to the
distance between the sensor and the
near and far limits. These limits are
shown in the illustration above as Dwi
and Dwo. When D is equal to one of the
two limits, according to the level-control
functions, an output change takes place.
A red LED illuminates when the output is
in an active (On) state.

Level-Control Functions
The level control output in the Model
SM902 Series can be configured for
many different operating functions.
Through the Model Reference Guide, the
sensor can be selected to perform a
pump-in latch function, pump-out latch
function, dual-setpoint function, dual
alarm, or a combination of these
functions.
Pump-in Latch
When the level moves farther than the
far limit, the sensor level control output
switches state and latches, starting a
pump-in process.The sensor level
control output does not change state

Setting the
Window Limits
Located on the backside of the sensor,
the SETUP pushbutton is used to set the
near and far window limits within which
the level sensing is to take place. Before
the limits are set, the sensor must be
properly aligned with the object to be
detected.
flashing green, align a flat object
parallel to the sensor face at the center
of the desired window and press the
SETUP pushbutton twice in succession
without moving the object. An automatic
default window limit will be set at a
distance equal to half the default
window in front of and behind the flat-
object surface nearest the sensor. If, for
example, the functionality of the 1- or 2-
meter-range sensor calls for the stan-
dard default window, the sensing
window is set with limits 6.35 mm (0.25")
in front of and behind the object’s front
surface.
For long distances or tall-tank applica-
tions, when use of the sensor’s push-
button is not practical, an optional,
Model AC441 Handheld Configurator
can be used to set or change the near
and far window limits and display the
object distance when the sensor is
located up to 200 feet from the user.
The Model AC441 cannot, however, be
used to set the default window.
Once set, the window limits are saved
in nonvolatile memory and thus are
retained when power is removed from
the sensor.
Loss of Echo Operation
Output Off, On Loss of Echo
Loss of echo occurs when the sensor
does not receive echoes from an object
or surface level within its sensing range
for more than one second for the 1- and
2-meter sensing range and 4 seconds
for the 7.6-meter sensing range. When
this occurs, the sensor’s output automati-
cally switches OFF. When the sensor
again receives echoes, the output
assumes the state relative to the dual-
level control or dual-setpoint limits.
Output Holds, On Loss of Echo
(“LE” Option)
The LE suffix in the Model Reference
Guide indicates an available option for
users who do not prefer the standard
response to loss of echo. With the LE
option, when loss of echo occurs, there
is no change in the output state of the
sensor. When the sensor again receives
echoes, the output assumes the state
relative to the dual-level control or dual-
setpoint limits.
until the level moves back closer than
the near limit to stop the pumping
process.
Pump-out Latch
When the level moves farther than the
far limit, the sensor level control output
switches state and latches, stopping
pump-out process. The sensor level
control output does not change state
until the level moves back closer than
the near limit to restart the pumping
process.
Dual Setpoint
Two sensor outputs are used to enable
this control function. One output oper-
ates independently with the near set-
point limit while the other operates
independently with the far setpoint limit.
The near setpoint limit output switches
state when the level moves closer than
the near setpoint limit and does not
switch back until the level moves farther
than the near setpoint limit.
The far setpoint limit output switches
state when the level moves closer than
the far setpoint limit and does not switch
back until the level moves farther than
the far setpoint limit.
Dual Alarm
Two sensor outputs are used to enable
this control function. One output oper-
ates independently with the near alarm
limit while the other operates indepen-
dently with the far alarm limit. The near
alarm limit output switches state when
the level moves above (closer than) the
near alarm limit and changes state when
the level moves back below (farther
than) the near alarm limit. The far
setpoint limit output switches state when
the level moves below (farther than) the
far alarm limit and changes state when
the level moves back above (closer
than) the far alarm limit. As a fail-safe,
the Normally Open (N.O.) dual alarm
outputs are physically active when the
level is between the alarm limits and
physically inactive when in an alarm
condition.
Pump Latch with Alarm/Setpoint
This control function uses a combina-
tion of the above Level Control
Functions.
To set the window limits, depress the
SETUP pushbutton (the multicolor LED
rapidly flashes amber to indicate the
pushbutton is being pressed) until the
multicolor LED flashes green in about 3
seconds, and then release the SETUP
pushbutton. The multicolor LED contin-
ues flashing green indicating the sensor
is waiting for the first window limit. Align
a flat object parallel to the sensor face at
the desired distance position for either
the near or far window limit, and press
the SETUP pushbutton once. Upon
release of the SETUP pushbutton, the
multicolor LED flashes amber indicating
the first window limit is set and the
sensor is waiting for the second window
limit. Align a flat object parallel to the
sensor face at the desired position for
the second window limit and press the
SETUP pushbutton once. Upon release
of the SETUP pushbutton, the multicolor
LED turns to the color that indicates
where the object is located. The sensor
has no time-out for setting limits.
For sensor models with a control
output and either an alarm or setpoint
output, the alarm or setpoint limit is set
after the window limits are set. With
these models, after the SETUP push-
button is pressed for the second window
limit and released, the multicolor LED
flashes amber/green indicating the
second window limit is set and the
sensor is waiting for either the alarm or
setpoint limit. Align a flat object parallel
to the sensor face at the desired position
for either the alarm or setpoint limit and
press the SETUP pushbutton once.
Upon release of the SETUP pushbutton,
the multicolor LED turns to the color that
indicates where the object is located.
While the SETUP pushbutton is
depressed, the multicolor LED turns
amber to indicate the sensor detects the
object. If the sensor does not detect the
object, the multicolor LED is red while
the SETUP pushbutton is depressed,
and flashes 2 seconds when the SETUP
pushbutton is released. After flashing
red 2 seconds, the sensor requests that
window limit again by flashing green for
the first window limit or flashing amber
for the second window limit.
A special feature of these sensors
allows the user to set an automatic
default window of fixed size anywhere
within the sensing range. For the 1- and
2-meter-range models, the standard
default window is 12.7 mm (0.50"). It is
127 mm (5.00") for the 8-meter-range
models. Other default window sizes are
available for all the models upon
request. To easily set the default
window, while the multicolor LED is
