Arlyn Scales’ Ultra Precision line delivers up to 10x more accuracy than strain gauge scales — with rugged durability, plug-and-play connectivity, and pricing that beats other high-precision alternatives. Powered by our patented SAW (Surface Acoustic Wave) technology, these scales are redefining what’s possible in industrial environments.
Types of SAW Scales
SAW bench scales range from 10 to 200-pound capacities. For example, the Series 6200 strain gauge scales give excellent readability of 0.02 lb with a capacity of 100 lb. The D-620C doubles that readability to 0.01 lb, with the same capacity. Our SAW-C Ultra Precision unit provides an incredible readability of 0.001 lb, also with 100 lb capacity.
Each industrial weighing application requires different levels of accuracy and resolution. But every application needs bench scales that are well designed, durable, cost-effective and easy to use. A stainless steel load cell means you’ll have a scale that can handle rough use and still provide precise weight results.
Platform SAW scales can take on additional weights from 200 to 1,000 pounds. Recent advances now allow the SAW scales to take on as much as 1,000 pounds. The highly sensitive acoustic wave sensor delivers its piezoelectric punch not as hardware, but as technology.
This powerful scale comes in a very compact, fixed table-top form with a built-in keypad and display that makes it easier to be used in cleanrooms and other laboratory or industrial environments.
Intrinsically Safe Ultra Precision Scales are ideal for any industrial environment classified as hazardous due to explosive fumes, liquids, or high concentrations of dust. These scales can be configured in multiple ways to meet a range of unique applications, including AC powered systems and Safe Area display configurations. These scales are intrinsically safe for use in Class I, II and III; Division 1; and Groups A, B, C, D, E, F and G.
SAW Scale Specifications
Our Ultra-Precision scales are backed by a three-year warranty and are made to last. The scales are constructed of a die-cast aluminum shell with a stainless steel weighing pan and toggle switches.
We fabricate our SAW transducers using semiconductor-grade crystalline substrates and deposit sensitive electronics thereon using the same photolithography process used to manufacture advanced semiconductor devices. This ultimately makes our SAW load cells inherently more accurate than strain gauge units because they produce a fully digital output stream that results in precise, high-resolution measurements.
This combination of accuracy and features lead to precise readings along with many different connectivity options that will work with these scales. For instance, you may need a special device that has an extremely high readout resolution because extremely slight differences are considered to have significant importance in your line of work. Should this sound familiar, then you might want to check out some of our special displays.
These scales offer an easy-to-see large, back-lit LCD dual display with multiple weight units. There are parts counting and check weighing functions, as well as automatic zero tracking and stability control. You could also consider using any of the various computer interfaces that are available for our scales, which allow you to hook up peripherals to the equipment that you’re working with. Since these are based on standard technologies that you more than likely already have the gear to interface with, you shouldn’t have any issues.
Consider, for example, how some displays use USB connectivity. This is a nearly universal standard at this point, which is included on so many different devices that it can be difficult to count. More than likely, you’ve even seen consumer-grade radios that have USB ports! As a result, it wouldn’t be difficult at all to find a computer in your department to plug into and get a stream of data from the most accurate scale you’ve ever worked with.
Computer enhancement options include RS-232 and Ethernet. There are rechargeable battery packs and set-point controllers for automatic filling and other upgrades. SAW scales require no professional set up. You can easily start using the scale immediately, and no calibration is necessary.
How Does SAW Technology Work?
Traditional Weighing Technologies: Before SAW, most high-precision scales used either:
- Strain Gauge Technology – Measures changes in electrical resistance when weight bends a spring element. Cost-effective, but limited in accuracy.
- Force Restoration Technology – Measures the electrical current needed to support the object. Highly accurate, but expensive and fragile.
SAW Delivers the Best of Both Worlds: Surface Acoustic Wave (SAW) technology uses a completely different approach. Instead of measuring force or resistance, SAW uses time-based measurements to calculate weight.
Here’s how it works:
- Two transducers — a transmitter and a receiver — are fixed a precise distance apart.
- When weight is applied, the spring element bends, changing the distance between the two.
- A surface acoustic wave travels between the transducers, and the travel time changes based on the applied load.
- This signal is converted directly into a digital weight reading — with no analog interference or signal drift.
This process allows SAW-based scales to deliver extremely high resolution and accuracy — even in harsh industrial environments.
Why You Should Use Ultra Precision Scales
If you need more accuracy than a standard gauge scale can offer, then you need an Ultra Precision Scale from Arlyn Scales. These scales provide 10 times the accuracy of standard scales and feature a rugged design perfect for rough industrial use. They can offer sensitivity ratings as low as .0001, and their accuracy falls between .01% and .005%. While you should be careful of overloading, accidents happen. That’s why Ultra Precision Scales can accept up to 2.5 times the rated load without damage.
Who Can Benefit From Using These Scales?
We believe anyone can benefit from a more accurate scale, but this especially applies to those working with pharmaceuticals, chemicals, industrial paints and adhesives, and electronics. When you work in these industries, the slightest inaccuracy can have severe consequences. With our Ultra Precision Scales, you get the accurate measurements you need as well as a durable design that can stand up to spills and heavy loads. Don’t forget about the Intrinsically Safe Ultra Precision Scale that is appropriate for hazardous environments.
