Arlyn Scales makes a line of ultra-precision scales utilizing our own Surface Acoustic Wave technology and built rugged enough for industrial use. They are much more accurate than standard industrial scales. They provide a wide range of high capacity, high resolution weighing platforms for demanding weighing applications.
Features That Qualify Precision Scales For Industrial Use
Although precision weighing is highly desirable in industrial settings, most precision instruments of any kind are not suitable. Analytical balances are very prone to damage from overload. Shock load, which can be caused by dropping an item on the platform, is even worse, as mechanical stops will not protect the scale.
Accuracy And Precision
Standard industrial scales offer good weighing accuracy. A floor scale with a capacity of 1000 lb can show readings as small as 0.2 lb. A 100 lb bench scale with a high-quality load cell may show 0.02 lb. This may be suitable for many requirements.
But this may not be good enough for other applications. Pharmaceuticals, chemicals, electronics, and colorants are just a few examples of industries that often require superior results. An alternative technology, such as Arlyn Scales’ Surface Acoustic Wave scales are required.
The Ultra Precision floor scale with a capacity of 1000 lb provides readability of 0.01 lb. This is twenty times better than the standard scale. Similarly, a 100 lb bench-scale reads out in increments of 0.001 lb.
Ruggedness
Excellent precision is of little value if it cannot be used on the factory floor. Most high-precision scales use a type of technology utilizing a precision electromagnetic coil to develop a magnetic field. This is used to counterbalance the amount of weight on the platform with the amount of current that must be applied to this coil.
By its nature, this type of technology is delicate and prone to damage. It is also limited in the overall capacity of the scale. When the desired scale capacity is too high it becomes impractical to develop large enough opposing magnetic fields.
Arlyn’s ultra-precision scales utilize a unique technology that eliminates the requirement for a magnetic field. Instead, a large block load cell incorporates two surface acoustic wave transducers. As the rugged load cell receives the load, the distance between the transducers changes by a very small amount, which changes its operating frequency.
This series of precision scales avoids the weight capacity limitations associated with electromagnetic coil scales. The thickness of the bending areas of the load cell will dictate the overall scale capacity. Whereas current models are available with a capacity of 1000 lb, larger units may be custom ordered.
Easy To Read Digital Displays
Ultra-precision is no longer relegated to the laboratory. But in order to use these scales in the manufacturing world, the user interface must be suitable. Most importantly, the weight readout must be clear enough and large enough for the operator to view.
Graphics LCD displays can solve both of these problems. Arlyn’s standard indicator boasts large block digits. Additional indicators on the display denote the units of measurement, along with other operating parameters.
The optional UpScale weight indicator offers a backlit 7” color touchscreen. Various display modes automatically appear depending on the currently selected functions. There is even a large “scoreboard” style display for long-distance viewing.
When the unit is provisioned as a counting scale, the appropriate function buttons appear. When the user performs a calibration procedure, interactive menus prompt the user to apply the calibration weight.
Quality Materials
High-quality scales require the appropriate materials. By its nature, the ultra-precision scales are very robust. That carries through to the materials used for the load cell, and the choice of stainless steel for the scale platform.
Types Of Precision Scales
Many industrial applications do not require superior accuracy. But those that do may be needed for specific types of uses. A broad product line can be crucial.
Ultra Precision Scales
These scales are available in low weight, medium weight, and high weight capacities. The platform size corresponds to the weight capacity.
Precision Counting Scales
A standard industrial task is to count the total number of parts in a batch. A parts counting scale is very useful when these parts are identical in weight to each other. This will often be the case with hardware items, stamped parts, and electronic components.
A single part may be placed on the scale platform to determine its weight. This is known as the piece weight. When a batch of those same parts is now put onto the scale, the total number of parts can be calculated by dividing the piece weight into the measured weight.
The accuracy of the final count that is calculated is limited by the accuracy obtained by weighing the sample. Often, multiple sample pieces are used in order to increase this accuracy. An ultra-precision scale will further enhance the accuracy of the result.
Explosion Proof Ultra Precision Scales
Classified, or hazardous environments are usually associated with flammable or explosive materials. Arlyn’s approved explosion-proof scales are often the only choice when formulation parameters require high accuracy.
