OHAUS Defender™ 3000 Advanced Industrial Platform Scale

Overview

The OHAUS Defender™ 3000 Advanced Industrial Platform Scale is a high-reliability, precision weighing solution engineered for demanding industrial, logistics, warehouse, and commercial trade applications. Built upon a robust structural architecture with reinforced load-bearing frame and optimized weight distribution mechanics, the scale operates on the fundamental principle of strain-gauge-based force transduction—where mechanical deformation of calibrated alloy steel load cells is converted into proportional electrical signals via Wheatstone bridge circuitry. Each unit integrates four OIML R60 Class III–certified load cells, ensuring metrological traceability and long-term repeatability under continuous heavy-duty cycles. The platform’s modular design supports seamless integration into production lines, shipping docks, and quality control stations where accuracy, durability, and environmental resilience are non-negotiable.

Key Features

• Four high-strength alloy steel load cells certified to OIML R60 Class III and NTEP Class III standards—guaranteeing legal-for-trade compliance in North America, EU, and APAC markets.
• IP67-rated load cells and IP65-rated stainless-steel junction box—enabling reliable operation in wet, dusty, or washdown environments typical of food processing, chemical handling, and recycling facilities.
• White backlit LCD display with large, high-contrast digits (25 mm height) and intuitive icon-driven interface—optimized for readability under low-light or high-glare conditions without requiring ambient lighting adjustments.
• Structural platform options spanning eight standardized configurations—including compact 0.8 m × 0.8 m decks for benchtop material staging and expansive 2.0 m × 2.0 m surfaces for palletized cargo verification—each engineered with reinforced perimeter gussets and internal cross-bracing to minimize deflection at rated capacity.
• Factory-calibrated with dual-point linearization and temperature-compensated zero tracking—reducing drift over operating temperatures ranging from –10 °C to +40 °C.
• Integrated overload protection up to 150% of maximum capacity—preserving sensor integrity during accidental overloading or dynamic impact events.

Sample Compatibility & Compliance

The Defender™ 3000 accommodates a broad spectrum of sample forms—from loose bulk materials (e.g., aggregates, grain, scrap metal) and rigid containers (IBC totes, steel drums) to palletized goods with standard EUR/ISO footprint dimensions. Its load cell configuration and platform rigidity ensure minimal corner-loading error (< ±0.02% of full scale), meeting ANSI/AMMI C3.14 requirements for platform scale performance. All units are manufactured in an ISO 9001–certified facility and undergo 100% final verification per OIML R76–1 Annex D protocols. Documentation includes factory calibration certificate with uncertainty budget, NIST-traceable reference mass verification report, and CE/UKCA Declaration of Conformity. For regulated industries, the scale supports optional GLP/GMP-compliant audit trail logging when paired with OHAUS ACIS software.

Software & Data Management

Native USB and RS-232 interfaces enable direct connection to PCs, PLCs, or label printers for automated data capture. Optional OHAUS ACIS (Advanced Calibration & Integration Software) provides configurable data export formats (CSV, TXT), user-access-level management, electronic signature support, and 21 CFR Part 11–compliant audit trail generation—including timestamped records of calibration events, zero-setting, unit changes, and firmware updates. The scale also supports Modbus RTU protocol for SCADA and MES integration, facilitating real-time weight streaming into SAP EWM, Oracle WMS, or custom ERP modules without middleware dependency.

Applications

• Warehouse receiving and dispatch verification—validating inbound/outbound shipment weights against purchase orders or carrier manifests.
• In-process checkweighing in food, pharmaceutical, and automotive assembly lines—ensuring component fill consistency prior to packaging or subassembly.
• Recycling center material buy-back operations—accurately quantifying ferrous/non-ferrous scrap loads for contractual settlement.
• Construction site batching control—monitoring aggregate, cement, or additive volumes before concrete mixing.
• Logistics hub pallet consolidation—verifying gross vehicle weight (GVW) compliance prior to regional transport dispatch.
• Education and vocational training labs—teaching metrology fundamentals, calibration procedures, and legal-for-trade regulatory frameworks.

FAQ

Is the Defender™ 3000 approved for legal-for-trade use in the United States?

Yes—the DF32M1500BSZH model carries NTEP Certificate of Conformance #19-072C, authorizing its use in commercial transactions across all 50 states.
What environmental conditions can this scale withstand?

With IP67 load cells and IP65 junction box, it tolerates temporary submersion (up to 1 m for 30 min) and high-pressure washdown; ambient operating range is –10 °C to +40 °C.
Can it be integrated with enterprise resource planning (ERP) systems?

Yes—via Modbus RTU or ASCII serial output, enabling bidirectional communication with SAP, Oracle, Infor, or custom-built inventory management platforms.
Does it support external calibration with field weights?

Yes—internal calibration routine accepts external Class F1 or better test weights; procedure is guided step-by-step on-screen with pass/fail validation.
Is firmware upgrade capability available?

Yes—field-upgradable via USB flash drive using OHAUS-provided firmware packages; version history and checksum verification included in release notes.
