Up to 8 Meter RangeProximity Sensing

Whether the object beingdetected is just a few inchesfrom the sensor or as far away as26 feet, or the application callsfor a specific sensor configura-tion, the SUPERPROX ModelSM900 series of ultrasonicsensors offers a variety ofproximity sensing solutions.There is the mounting conve-nience of a 30 mm housing,sensing ranges of 1 m (39"),2 m (79"), and a long-range8 m (26'), the shortestdeadbands in the sensingindustry, and unique factoryconfigurability to meet the usersneeds. In addition to sensingranges, model selectionsinclude normally-open ornormally-closed NPN and PNPoutputs, complementary NPN orcomplementary PNP outputs,

and a variety of response timesand default sensing windowsetup limits. By using the ModelReference Guide to select thespecific model required, theuser is assured of a reliable,cost-effective proximity sensingsolution for a multitude ofapplications. All models in this series areequipped with a push-button toset the limits for the sensingwindow. When it is impracticalto use the push-button for settinglong-range sensing limits, anoptional, hand-held, setup/display accessory is available.All limits are stored in nonvolatilememory and thus are retained ifpower is removed from thesensor. The sensors are available ineither ULTEM plastic or SS303stainless steel housings. Bothhousings are sealed to withstanddusty, dirty, clean-in-place,noncondensing humidity, high-pressure washdown environ-ments. Unlike other sensingtechnologies, these sensors arecapable of detecting all materialsregardless of color, shape, andcomposition (transparent or

1 meter and2 meter models

The standard 1 meter and the 2 metermodels are identified in the ModelReference Guide as the ModelSM900A-1 and Model SM900A-4sensors, respectively. These modelsprovide for proximity sensing as close as50.8 mm (2") from the sensor within the1 m (39") range and 120 mm (4.7") fromthe sensor within the 2 m (79") range. Toensure ease of mounting, the length ofthe connector model, excluding theconnector/cable assembly, is just 96 mm(3.78"). These sensors operate on asonic frequency of 200 kHz and areavailable with response times as fast as10 ms. The transducer face is made ofFDA approved silicone rubber. For proximity-sensing applications insevere, corrosive-type environments, theModel SM900A-7STS sensor has anSS303 stainless steel housing and isequipped with an SS304 stainless steel-faced transducer. This model series, witha sensing range of 120 mm to 1 m (4.7"to 39"), provides reliable operation ineither the detection of certain chemicalsand corrosive materials or where causticcleaning solutions are used in wash-downs of machinery and equipment inclose proximity to the sensor. For out-of-doors, proximity-sensing applications,where cold weather is a factor, thiscorrosion-resistant model series pro-vides reliable operation in temperaturesas low as -10 C (14 F).

opaque, liquid or solid) including clearglass, powder, food products, metal,plastics, and objects that change colors.They are virtually unaffected bychanging light conditions, colors, andnoise. Packaged in a 30 mm, threadedhousing with jam nuts, the Model SM900sensors are easily mounted in normallytough-to-install areas of the plant. Withprotection ratings of NEMA 4X and IP67,the sensors resist most acids, bases,and oils, including most food products.All the sensors in this model series areCE certified. Additionally, the ModelSM900 series sensors offer compatibleintegration with most programmablelogic controllers.

for long-range proximity sensingapplications requiring a simple on/offoutput, these ultrasonic sensors detectobjects of all materials over a sensingrange from just 203 mm (8") to 8 m (26').With the length of the cable model only116.31 mm (4.579"), a fraction of thelength of other long-range sensors,these sensor models are easy to mount

Field configurable and DeviceNet Model Reference Guides start on page 4-145.

Applications Applications for these long-rangeproximity sensors extend to most everyindustry or business requiring reliabledetection within the range of 8 meters(26 feet). By virtue of the 75 kHzfrequency, the sensors wide, 20o beamis especially effective in detectingobjects with a variety of surface profiles.In applications where high soundabsorption conditions exist in thematerial being sensed, and either theone or two meter range model sensorbecomes unreliable because of lostenergy, the more powerful long-rangeSM900A-8 can provide the solution whenused in the shorter-range distances. Temperature compensation allows thesesensors to operate reliably in outdoorapplications in temperatures ranging from-10 to 60 C (14 to 140 F).

Operation The SUPERPROX Model SM900series is a self-contained, pulse-echo,proximity sensing device that bothtransmits and receives sonic energywithin specified sensing ranges.Operating on 12 to 24 VDC, andemploying the latest piezoelectric andmicroprocessor technology, thesesensors detect only those designatedobjects within a set window and ignoreall surrounding sonic interference. Prior to operation, a simple and easypush-button teach function is used toset the sensing window limits. The nearand far limits of a desired sensingwindow can be set anywhere within thesensing range and may be set to eitherencompass the full sensing range orbe as small as desired. The push-buttonsetup allows a window to be set as smallas 2.54 mm (0.10") within the 1 and 2 mranges and, depending on ambientconditions, a window within the 8 mrange can be as small as 102 mm (4.0").A double press of the SETUP push-button makes possible the setting of adefault window anywhere within thesensing range. The sensors are equipped with a multi-color sensing status LED and a red LED.The red LED shows the state of the out-put. When the output is active, the redLED is on. When the output is not active,the red LED is off. The multicolor LEDindicates the position of the objectrelative to the sensing window limits:green when the object is inside thewindow; red when the object is outsidethe window; and off when the object isoutside the sensing range. Two different sensing programconfigurations, both employing fore-

ground and background suppression,are available in the SM900 series,depending on the sensing application. The standard sensing configuration,used in most proximity sensing applica-tions, calls for the sensor to operate in abackground sensing mode. In thismode, the sensor can detect objectseither directly or retroreflectively bydoing a break-beam technique with afixed background target. When objectsare of irregular shape or non-repeatableorientation, break-beam sensing with afixed background target should be used.After the sensing window is set to sensean object or the background target, thesensor continually transmits sonicpulses.

When the first pulse echo is receivedafter each transmission pulse, thesensor shuts off its receiver and interro-gates the elapsed travel time of thereceived first echo to determine whetherthe object is in or out of the sensingwindow. The sensors receiver thenwaits for the next echo to interrogate.When either no echo is received, or thefirst echo received off an object travelsa lesser or greater distance than thewindow distance, the sensor determinesthere is no object present. Whensensing objects by break-beam with afixed background target, the sensordetermines there is no object presentwhenever receiving echoes off thebackground target. An optional object sensing modeconfiguration is recommended when thesensor must sense objects beyond aforeground surface having an openingthat permits reception of the pulseechoes. An example would be thesensing of an object through a grid orinside a narrow opening. Sensing in thismode is done by setting the sensingwindow limits beyond the foregroundsurface. During operation, the sensorreceives all pulse echoes from objects infront of it, including the foregroundsurface, without interruption. But, in thismode, the discriminating microprocessorpermits the sensor to accept only thosepulse echoes from objects that are withinthe sensing window limits and ignoreany foreground objects.

Exception:Exception:Exception:Exception:Exception: Multiple echoes receivedoff objects at either 1/2 or 1/4 distancesfrom the sensor to the window may beaccepted or confused as an object inthe sensing window. This is avoided bymounting the sensor in a position wherethis condition cannot exist.

Setting the Window Limits Located on the backside of the sensor,the SETUP push-button is used to setboth the near and far window limitswithin which the sensing is to take place.Before the limits are set, the sensor mustbe properly aligned with the object to bedetected. To set the near and far limits, depressthe SETUP push-button (the multicolorLED rapidly flashes amber to indicatethe push-button is being pressed) untilthe multicolor LED flashes green inabout 3 seconds, and then release theSETUP push-button. The multicolor LEDcontinues flashing green indicating thesensor is waiting for the first windowlimit. Align a flat object parallel to thesensor face at the desired distanceposition for either (near or far) windowlimit, and press the SETUP push-buttononce. Upon release of the SETUP push-button, the multicolor LED flashes amberindicating the first window limit is setand the sensor is waiting for the secondwindow limit. Align a flat object parallelto the sensor face at the desired positionfor the second window limit and pressthe SETUP push-button once. Uponrelease of the SETUP push-button, themulticolor LED turns to the color thatindicates where the object is located.The sensor has no time-out for settinglimits. While the SETUP push-button isdepressed in setting either the first orsecond window limit, the multicolorLED will turn amber to indicate thesensor detects the object. If the sensordoes not detect the object, the multi-color LED will turn red while the push-button is depressed and flash red 2seconds when it is released. After theLED flashes red 2 seconds, it will eitherflash green if the sensor is requestingthe first window limit again or flashamber if the sensor is requesting thesecond window again. A special feature of these sensorsallows the user to set an automaticdefault window of fixed size anywherewithin the sensing range. For the 1 and2 meter range models, the standarddefault window is 12.7 mm (0.50"). It is127 mm (5.00") for the 8 meter rangemodels. Other default window sizes areavailable for all the models uponrequest. To easily set the defaultwindow, while the multicolor LED isflashing green, align a flat object parallelto the sensor face at the center of thedesired window and press the SETUPpush-button twice in succession withoutmoving the object.

window limit will be set at a distanceequal to half the default window in frontof and behind the flat-object surfacenearest the sensor. If, for example, thefunctionality of the 1 or 2 meter rangesensor calls for the standard defaultwindow, the sensing window is set withlimits 6.35 mm (0.25") in front of andbehind the objects front surface. For long distances or tall-tank applica-tions, when the sensors push-button isnot practical, an optional, ModelAC441A Handheld Configurator can beused to set or change the near and farwindow limits and display the objectdistance when the sensor is located upto 200 feet from the user. The ModelAC441A cannot, however, be used toset the default window. Once set, the window limits are savedin nonvolatile memory and thus areretained when power is removed fromthe sensor.

How Does it work?During setup and operation, theseSM900 series sensors continually andaccurately measure the elasped time ofevery pulse echo reception betweeneach pulse transmission. The transmittedpulse begins a time clock to register theelasped times for the received pulseechoes. Given the elasped time, thesensor software calculates the distancetraveled out to the object or surface andback to the sensor, using the formula, D= TVs/2, where: D = distance from thesensor to the object; T = elasped timebetweem the pulse transmission and itsecho receptions, Vs = the velocity ofsound, approximately 1100 feet persecond. During operation, the calculateddistance (D) between the sensor and theobject is compared to the distancesassociated with the window limits. Theselimits are shown in the illustration atlower right as Dwi and Dwo. If D is within these limits, an output isgenerated. The output remains on untilthe echo does not return or it returnsfrom outside the window limits. PULSE
