OHAUS Defender 5000 Series Heavy-Duty Platform Scale DF52XW3000WXZH

Overview

The OHAUS Defender 5000 Series Heavy-Duty Platform Scale DF52XW3000WXZH is an industrial-grade floor scale engineered for precision, durability, and long-term operational reliability in demanding production, logistics, and quality control environments. Built upon a robust dual-layer structural architecture with a low-profile 90 mm ground clearance, this platform scale employs load cell-based force measurement technology compliant with OIML R60 accuracy class C3 (or higher, depending on configuration), ensuring traceable, repeatable mass determination under dynamic and static loading conditions. Its design prioritizes mechanical integrity over aesthetic minimalism—featuring a 6 mm chequered steel or stainless-steel top plate (8 mm for 5-ton variants) and a 4 mm U-channel subframe formed via high-precision press-braking. The system undergoes certified fatigue validation—500,000 full-scale load cycles—demonstrating resilience against repeated impact, off-center loading, and thermal cycling typical in warehouse, foundry, and agricultural processing settings.

Key Features

• Structural Integrity: Dual-layer frame with 6 mm (or 8 mm for ≥5 t) chequered steel/stainless-steel deck and 4 mm press-formed U-channel base for torsional rigidity and load distribution uniformity.
• Load Cell System: Four OIML R60-certified alloy-steel load cells (IP67-rated); stainless-steel variants utilize hermetically welded IP68 load cells for enhanced corrosion resistance in washdown or humid environments.
• Environmental Protection: IP65-rated all-stainless-steel junction box; optional IP67/IP68-rated enclosures available for full-system ingress protection.
• Low-Profile Design: 90 mm deck-to-floor height minimizes ramp requirements and improves operator ergonomics during palletized or cart-based weighing.
• Modular Connectivity: Standard RS232 interface for direct connection to PCs, label printers, or PLCs; optional expansion modules support Bluetooth 5.0, dual RS232/RS485, USB host/device, Ethernet (TCP/IP), and analog I/O (4–20 mA / 0–10 VDC) or digital I/O (2-in / 4-out) for process integration.

Sample Compatibility & Compliance

The DF52XW3000WXZH accommodates standard industrial payloads including palletized goods, drums, crates, livestock feed containers, and bulk material bins. Its rigid deck geometry supports both centered and off-center loading within specified eccentricity limits per OIML R76. The scale complies with international metrological standards including OIML R60 (load cells), OIML R76 (non-automatic weighing instruments), and EU Directive 2014/31/EU (NAWI). For regulated manufacturing environments, firmware supports audit-trail logging and user-access control—facilitating alignment with GLP, GMP, and ISO 9001 documentation requirements. Optional NIST-traceable calibration certificates and factory-assembled verification kits are available upon request.

Software & Data Management

The integrated indicator features embedded firmware supporting six core weighing modes: static weighing, checkweighing (with configurable upper/middle/lower limits and visual/audible alerts), parts counting (with sample-weight averaging), percentage weighing (relative to reference mass), dynamic weighing (for unstable or moving loads), and hold mode (peak-hold or stable-value capture). Data export is supported via ASCII protocol over RS232 or TCP/IP; third-party SCADA, MES, and ERP systems can ingest weight data using Modbus RTU/TCP or custom CSV streaming. Firmware updates are performed via USB flash drive or network push; configuration parameters—including unit selection, decimal places, filtering, zero-tracking behavior, and I/O logic—are retained across power cycles and firmware revisions. All configuration changes are timestamped and logged internally for compliance review.

Applications

This platform scale serves as a foundational metrology node across multiple sectors: incoming raw material inspection in food processing plants; batch verification and filling control in chemical and pharmaceutical manufacturing; outbound pallet verification in 3PL and e-commerce fulfillment centers; livestock and feed management in agritech operations; and scrap metal or recyclables sorting in metal recycling facilities. Its ruggedized construction and configurable I/O make it suitable for integration into automated conveyor lines, where weight-triggered sorting, labeling, or rejection decisions are executed in real time. In maintenance-intensive environments—such as shipyards or rail depots—the stainless-steel variant withstands exposure to salt spray, hydrocarbons, and abrasive particulates without degradation of metrological performance.

FAQ

What accuracy class does the DF52XW3000WXZH meet?

It conforms to OIML R60 C3 accuracy class for load cells and OIML R76 Class III for non-automatic weighing instruments.
Is the scale suitable for outdoor use?

Yes—when equipped with IP67/IP68 load cells and IP65/IP67-rated electronics, it operates reliably in covered outdoor areas subject to rain, dust, and temperature fluctuations between –10 °C and +40 °C.
Can the scale interface with a PLC or SCADA system?

Yes—via optional RS485 (Modbus RTU), Ethernet (Modbus TCP), or discrete I/O signals for start/stop, zero, tare, and pass/fail outputs.
Does it support calibration traceability to national standards?

Yes—NIST-traceable calibration certificates and on-site verification services are available through OHAUS authorized service partners.
What is the maximum permissible off-center load distance?

Per OIML R76 Annex D, the maximum eccentric load position is defined by the manufacturer’s declared test zone—typically 0.2 × platform length/width for Class III applications.
