Scientific research is at the forefront of innovation and progress. Understanding the how’s and wherefores can save lives due to the shedding of light on a particular subject, which may provide clues to curing age-old diseases. Science also aids societies in keeping track of emerging health issues by establishing significant criteria concerning health, environment, food sources and water quality.
It is for this reason that multiple companies have concentrated their efforts on raising the bar of precision and accuracy. Companies such as Arlyn Scales have placed a high priority on developing scales that would lend themselves to the world of science.
With the emphasis on precision and accuracy, it was important to research the device that is at the crux of weighing data. With a concentrated effort, Arlyn’s team of engineers introduced a solid innovative technology that would raise the bar of accuracy and precision forever. Called surface acoustic wave technology, this patented innovation includes similar technology that garners weight measurement using a spring element load cell without the disadvantages found in strain gage load cells.
The weight measurement is taken in time measurements and read in a digital format in fractions of a second. The load cells used in this technology differ in that they measure displacement as opposed to measuring stress or strain. The amount of displacement required is minute so there is practically no stress on the load cell. This methodology delivers the most accurate readings available in today’s marketplace.
With the use of Surface Acoustic Wave technology, these solid block load cell transducers use semiconductor technology making them very sensitive to minute amounts of weight. The high-resolution rates enable the incremental weight readings, which form the basis of all scientific research.
The construction of our scales occurs in our New York based warehouse with our own subassemblies. For this SAW Series, one large load cellblock is used in order to guarantee extremely precise and consistent weighing data. The stability of this technology is due in fact to its ability to remain consistent in the face of temperature variables and to its material composition. These transducers include lithium niobate, which is a specialized crystalline substrate.
This scale is constructed with a die cast aluminum frame, stainless steel weighing pan and click type switches. They come precalibrated and require no dealer set up. The out of the box feature adds to the cost savings of SAW scales. These scales have prices comparative to high-end strain gage scales, which is much less than all other scales with similar accuracy.
Shock and overload damage have become an issue of the past with these scales that are rated at 500 percent overload capacity. Compared to the ratings of 150 percent overload capacity of strain gage scales, the added security of this accurate instrument is an added plus.
The use of this semiconductor-like transducer has another added benefit. In the past, it was necessary to convert the analog reading to a digital weight reading. With this new technology, it takes a fraction of a second for a digital weight reading to appear on the scale’s digital indicator. With updates at four tenths of a second, information can be captured before the disintegration of time sensitive substances and will capture incremental weight changes precisely.
To accommodate larger weighing substances, this technology is available in our Ultra Precision Scales, which accommodate substances from ten pounds to substances as heavy as five hundred pounds. The high accuracy and precision rates accompany these larger capacity scales. It is important to note that utilizing scales within the weight range of the weighing substance yields the most accurate and precise weighing data. It is not recommended to use a larger capacity Ultra Precision Scale for measuring minute substances as it is the incremental weight readings that are important in experiments that require the mixing of chemicals and the monitoring these formulations.
Creep rating represents the measure of change in measured weight over time, such as when a weight is placed on a scale for a long period of time. Output measurements will differ and will change the longer the item rests on the scale’s platform. This effect is based on the elastic property of the material used in the load cell. Cheaper materials can result in very large creep values. The Creep rating is substantially lower in our High Precision scale with SAW technology, 1:40000 as compared to 1:5000 in the best Strain Gage Scale. We use the best large load cellblock available to allow for consistency and reliability.
The Included Digital Indicator is capable of demonstrating fifteen different weighing units. This easy to program and easy to read LCD dual display has parts counting, check weighing function, automatic zero function and stability control.
This digital indicator comes with RS-232 Protocol interface. This protocol allows communication between one piece of computerized equipment and another, making data transference between the scale and a printer, computer or programmable logic controller feasible. The bi-directional capacity allows for the printing of complex labels as well as the controlling of the scale from a remote location.
The capacity to connect to a computer for organization of all data is accomplished through the RS-232 protocol and the addition of our optional WinWedge Software. This software captures data, time, date, group and item information that is input into the scales digital indicator. The entered information can be read via Microsoft Excel, Access or any other Window’s software.
