Large Ultra Precision Scales 20x Readability - Capacities from 90 kg (1g) to 450 kg (5g)
Overview
Arlyn’s Large Ultra Precision Scales deliver unmatched accuracy—up to 0.005% of full capacity—on robust, industrial-grade platforms built to withstand shock loads, temperature swings, and messy environments. Powered by our internationally patented Surface Acoustic Wave (SAW) technology, these high-capacity scales outperform standard strain gage systems by 10x–20x and rival Magnetic Force Restoration (MFR) balances at a fraction of the cost. With capacities from 200 lb to 1000 lb, overload protection up to 250%, and optional touchscreen controls and cloud connectivity, these scales are purpose-built for demanding workflows in aerospace, chemical formulation, pharmaceutical production, and any process where extreme precision meets industrial conditions.

Precision Without Compromise
SAW technology redefines industrial weighing. Unlike strain gage or MFR systems, our digital SAW sensors measure displacement, not strain—delivering laboratory-grade readability (down to 0.002 lb) even on large-capacity platforms. That means fewer scale swaps, more accurate batching, and better process control.Industrial-Strength Design
Each scale is built with a stainless steel frame and weighing pan, engineered to take abuse while delivering ultra-stable measurements. With 250% safe overload protection, accidental overloading won't derail your workflow—or damage your investment.Plug-and-Play Simplicity
All models arrive factory-calibrated and ready to go. No dealer setup, no service contracts, no headaches. Set up in minutes, not days.Scalable Integration Options
Add advanced capabilities like:- Touchscreen display (UpScale) with intuitive workflows
- Cloud-based monitoring and weight tracking (AxChange)
- Industrial automation protocols: MODBUS RTU/TCP, PROFINET, EtherNet/IP
- Wi-Fi, USB, Ethernet, and RS-232/485 outputs

How are Large Ultra Precision Scales different from standard industrial scales?
These scales use Arlyn’s patented Surface Acoustic Wave (SAW) technology, which provides 10x to 20x better accuracy than strain gage systems—without sacrificing durability. They're built for factory environments but deliver lab-grade precision.
What kind of accuracy can I expect from these scales?
Depending on the model, the scales offer up to 0.005% of full scale accuracy. For example, our 1000 lb SAW-MXL model provides a 0.01 lb readability—far beyond typical industrial standards.
Are these scales suitable for rugged environments?
Yes. With a stainless steel frame and pan, plus 250% overload protection, these scales are designed for heavy industrial use. They can handle shock loads, drum impacts, and rough handling without compromising performance.
Do I need a technician to install or calibrate the scale?
No. Every scale is factory calibrated and ships ready to use. Simply plug it in and begin weighing. Field calibration is available via the front panel if needed, but no specialized setup or dealer service is required.
How do I integrate this scale with my existing systems?
We support a wide range of standard and industrial protocols, including RS-232, Ethernet, USB, Wi-Fi, MODBUS, PROFINET, and EtherNet/IP. Integration with SCADA, PLCs, MES, and cloud platforms is seamless using our optional indicators.
Is there a way to track weights remotely or over time?
Yes. Our AxChange Cloud Monitoring platform allows you to monitor weight data from any device, log historical values, and set up alerts or triggers. You can also integrate with Google Sheets or use USB data logging with no PC required.
Can these scales be used for part counting or batching operations?
Absolutely. All models support Parts Counting, and upgrades are available for Setpoint Control, relays, and batching automation—ideal for packaging, kitting, or filling workflows.
Are custom platform sizes or multi-scale setups available?
Yes. We build custom platforms and multi-platform systems with single display output. Contact us to discuss your specific requirements.
Can I use these scales with a touchscreen interface?
Yes. The Arlyn UpScale Touchscreen Indicator is available as an upgrade. It provides a modern, full-color interface with advanced configuration options, automation protocols, and cloud access.
