Model SM906 Series SUPERPROX(R) Ultrasonic Analog Output Sensors Up to 8-Meter Span Measurement &Level Control Control levels and measure distances over spans of up to 8 meters (26 feet) with broad functionality and 30 mm mounting convenience In vast contrast to other selfcontained analog sensors, this new and smaller 30 mm, SUPERPROX(R) Model SM906 sensor series offers mounting convenience, broad functionality and a selection of three analog sensing spans encompassing a few inches from the sensor to as far away as 26 feet. Depending on the model selected and the distance or level of the material being measured or controlled, the sensors offer analog spans of 1 m (39"), 2 m (79"), and a long span of 8 m (26'). The capability is enhanced further with the shortest deadbands in the sensing industry of 51 mm (2"), 120 mm (4.7"), and 203 mm (8"), respectively. As shown in the Model Reference Guide, the SM906 series of ultrasonic analog sensors gives the user a wide selection of factory-configurable functionality to maximize the sensor's efficiency in specific analog sensing applications. In addition to the analog sensing span, the user may select a 0 to 10 VDC or 4 to 20 mA output that is either directly or inversely proportional, output state for loss of echo and power up, and response time. Also, a broad selection of sensing functionality configurations, with foreground and/or background suppression, makes possible optimum sensing discrimination. This includes, for example, the capability of monitoring levels in a tank while ignoring the paddles on the tank agitator. The 30 mm housing, 60% smaller than other analog sensors with equal functionality, provides a package for the SM906 that is easily installed, without positioning limitations, in covers and other hard-to-mount areas. The models in this series are equipped with a pushbutton to set the sensors' near and far span limits. When it is impractical to use the pushbutton for setting the long-range limits, an optional, hand-held, setup/display accessory is available. The two limits can be set for a span to either encompass the full range of the sensor or create a span as SUPERPROX(R) SM906 SERIES * Sensing spans of 1 m (39"), 2 m (79") and 8 m (26') * Easy pushbutton setup or optional hand-held, setup/ display accessory available for 8-meter models * Either 4 to 20 mA or 0 to 10VDC analog output; either direct or inverse proportional outputs * Epoxy sealed in tough ULTEM(R) plastic or stainless steel housing * Resistant to caustic materials and harsh environments * DeviceNet capability in 1- and 2meter models * CE certified 3-117 small as desired for precise level or distance control. A typical example of precise level control is when the application calls for maintaining a constant fill level in a filler machine. In this example, the analog output provides a means of controlling the product flow into the filler as the filler speed changes. The analog output may provide a means for controlling the speed of other machinery as well as regulate the movement of control valve actuators. The analog output may also connect directly to programmable controller analog input modules for performing complex loop control or simple status (e.g., distance measuring) monitoring functions. All control 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 composition, transparent or opaque, including powder, food products, grains, chemicals, pharmaceuticals, oils, plastics and objects that change colors. The threaded housings are available in ether ULTEM(R) plastic or SS303 stainless steel which are epoxy encapsulated to withstand shock and vibration. Both housings 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. In meeting 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. 1-meter- and 2-meterspan models For purpose of definition, the standard 1-meter-span models are identified in the Model Reference Guide as the Model SM906A-1 and SM956A-1 series sensors and the 2-meter-span models are identified as the Model SM906A-4 and SM956A-4 series sensors. Respectively, these models provide for analog output sensing from 50.8 mm to 1 m (2 to 39") and 120 mm to 2 m (4.7 to 79"). The 96 mm (3.78") length of the connector model, excluding the connector/cable assembly, adds to the sensor's installation convenience. Operating on a sonic frequency of 200 kHz, these sensors have a standard response time of 25 ms and 35 ms for the 1- and 2-meter-span models, respectively with others available as shown in the Model Reference Guide. The FDA approved silicone rubber transducer, 3-118 while used to couple the ultrasonic energy to the air, is also resistant to most acids, bases and oils and food products. Selected 1- and 2-meter-span sensors have DeviceNet capability. Various functional choices plus the mounting convenience of a 30 mm housing combine to achieve reliability and cost effectiveness for these models in the detection of moving object positions in specific sensing applications. These include: monitoring and controlling levels of liquids and solid materials in bins and filler bowls, controlling container flow on mass conveyors, monitoring and controlling roll diameters and speeds, webs of paper and fabrics, extrusion widths, tension, dancer loops and valve positions, as well as the modulation of variable-speed motors, pumps and winding/unwinding equipment. For 1-meter-span, analog-output sensing applications that require measurement and control capability in severe, corrosive-type environments, the Model SM906A-7STS and Model SM956A-7STS series models have an SS303 stainless steel housing and an SS304 stainless steel-faced transducer. With an analog sensing span of 120 mm to 1 m (4.7 to 39"), these sensors provide reliable operation in either the detection of certain chemicals and corrosive materials or where caustic cleaning solutions are used in washdowns of machinery and equipment in close proximity to the sensor. For out-of-doors, analog-sensing applications, where cold weather is a factor, this corrosion-resistant model series provides reliable operation in temperatures as low as -10 C (14 F). 8-meter, long-span models The Model SM906A-8 and Model SM956A-8 series represents the only analog sensors on the market that offers the combination of shortest deadband, longest span and smallest package. As indicated in the Model Reference Guide, these sensors measure and monitor the position and level of objects over a sensing span of just 203 mm (8") to 8 m (26'). With this shortest dead- band, the need to position the sensor at great distances from the object, typical of most long-span sensors, is eliminated. At only 116.31 mm (4.579") in length for the cable-style model, a fraction of the size of other long-span sensors, these 30 mm diameter sensors are easily mounted in covers and other tight spaces in the plant. They operate on a sonic frequency of 75 kHz with a standard response time of 250 ms and a minimum response time of 150 ms. Other response times are available. An epoxy transducer face, 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. By virtue of the 75 kHz frequency, the sensor's wide, 20-degree beam is especially effective in sensing the tank or bin levels of various types of liquids, solids and granules. This includes applications involving the blending of ingredients and the processing of food products and pharmaceuticals, as well as the treatment of water and sewage. For outdoor analog output applications, the sensors have temperature compensation for operation in temperatures ranging from -20 to 60 C (-4 to 140 F). In applications where high sound absorption conditions exist in the material being detected, (e.g., tiny plastic pellets), and either the 1- or 2-meter span model sensor becomes unreliable because of lost energy, the more powerful long-span SM906 can provide the solution when used in the shorter-span distances. Operation The SUPERPROX(R) Model SM906 series is a self-contained, pulse-echo device that both transmits and receives sonic energy within the specified analog span. Operating on 15 to 24 VDC, these sensors use the latest ultrasonic sensing and microprocessor technology that allows the sensor to ignore all surrounding sonic interference and detect only the designated object. During operation, the sensor monitors the distance to an object or level while generating a proportional analog output relative to the two analog span limits. When an object is within the analog span, the analog output value changes proportionally in relation to the analog span limits. For example, if the object is half way between the analog span limits, the output is either 5 Volts or 12 mA, depending on the output model selected. The output range adjusts to the size of the analog span and remains proportional regardless of where the limits are set for the analog span. The sensors are equipped with a multicolor sensing status LED and a red output LED. The multicolor LED indicates where the level or target position is relative to the span limits. It is green when the object is between the analog span limits, red if closer than the near span limit, and amber if farther than the How does it work? During setup and operation, these SM906 series ultrasonic 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; and Vs = the Velocity of sound, approximately 1100 feet per second. During operation, the calculated distance (D) between the sensor and the object is compared to the distances between the sensor and the analog span limits. These limits are shown in the illustration below as Dwi and Dwo. If D is within the analog span limits, according to the selected sensing functionality configuration, a proportional output value for D, relative to the analog span limits, is generated.

As shown on this page, Hyde Park offers both direct and inverse proportional analog output models for continuous sensing applications.

This means the sensor is capable of detecting objects at certain distances and ignoring objects at other distances. An example would be in the monitoring of a level in a tank while ignoring the paddles on the tank agitator which would be closer than the near span limit. Each configuration employs a different algorithm to determine which echo returns are either accepted or ignored over the specified sensing range. Thus, these four configurations enable the sensor series to address a multitude of continuous-sensing, process-control applications. Use the following four illustrations as a guide in selecting the functionality best suited for the sensing application. Configuration: "00" - Standard: No foreground or background suppression With this configuration, the sensor processes only the first echo received from anywhere within the sensing span. Deadband: SM906 Series Near Span Limit Far Span Sensing Limit S pan The first echo return is processed. All other echo returns are ignored. Configuration: "01" - Foreground suppression only (object mode) With this configuration, the sensor ignores echoes received from objects closer than the near span limit and processes only the first echo received from between the near span limit and the sensing range. Deadband: SM906 Series Near Span Limit Far Span Sensing Limit S pan The first echo received between the near span limit and the sensing span is processed. All other echo returns are ignored. Configuration: "02" - Foreground suppression only (background mode) With this configuration, the sensor processes only the first echo received from an object. If the first processed echo from the object is closer than the near span limit, the echo is ignored and not processed. If the first processed echo from the object is between the near span limit and the sensing range, the echo is processed and the analog output value is updated. Deadband: SM906 Series Near Span Limit Far Span Sensing Limit S pan If the first echo return is received from closer than the near span limit, this echo and all subsequent echoes are ignored. Configuration: "03" - Foreground and background suppression (background mode) With this configuration, the sensor processes only the first echo received from an object. If the echo is received from between the near and far span limits, the echo is accepted and the analog output value is updated. If the echo is received from closer than the near span limit or farther than the far span limit, the echo is ignored and the analog output value is not updated. Deadband: SM906 Series Near Span Limit Far Span Sensing Limit S pan The first echo return received from between the span limits is processed. All other echo returns are ignored. Analog Output Response Function The analog output value is derived from the sensor response time and the object distance from the sensor. The "standard" response for the one-meter range sensing model is 25 ms and its analog output value is derived from the average of the last two echo returns. The "fast" response time for a one-meter range sensing model is 15 ms and its analog output value is derived from the last echo return. For sensors with other response times, the analog output value reaches 95% of the final output value in the stated response time using an exponential averaging function. Setting the Analog Span Limits Located on the backside of the sensor, the SETUP pushbutton is used to set both the near and far span 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 continues flashing green indicating the sensor is waiting for the first span limit. Align a flat object parallel to the sensor face at the desired distance position for either (near or far) span limit, and press the SETUP pushbutton once. Upon release of the SETUP pushbutton, the multicolor LED flashes amber indicating the first span limit is set and the sensor is waiting for the second span limit. Align a flat object parallel to the sensor face at the desired position for the second span 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. 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 when the SETUP pushbutton is released, the multicolor LED flashes red 2 seconds. After flashing red for 2 seconds, the sensor requests that span limit again by flashing green for the first span limit or flashing amber for the second span limit. Once set, span limits are saved in nonvolatile memory and thus are retained when power is removed from the sensor. Output State for Loss of Echo Selections As shown in the Model Reference Guide, four selections are available to address loss of echo conditions for specific applications. Selection "0" or "1" - Without Signal Hold on Loss of Echo On power-up or when no echoes are detected for one second, for the 1- and 2-meter sensing span and 4 seconds for the 8-meter sensing span, the analog output will go to a minimum value for selection 0 or a maximum value for selection 1. 3-121 SUPERPROX(R) SM906 SERIES Sensing Functionality Configuration Selection "2" or "3" - With Signal Hold on Loss of Echo If no echoes are received after powerup, the analog output value is a minimum when using selection 2 or a maximum when using selection 3. In addition, if echoes are not detected, the analog output value holds until echoes are once again received within the sensor's range. Multicolor LED Operation Redobject sensed closer than the near span limit. Greenobject sensed at or between the near and far span limits. Amberobject sensed beyond the far span limit. Offno object sensed within the full sensing range. Red LED Operation The red LED intensity varies directly with the magnitude or the analog output. The red LED is off when the output is at a minimum and full brightness when the output is at a maximum.
