Overview
The OHAUS Defender 5000 Series Heavy-Duty Platform Scale DF52XW3000WRZH is an industrial-grade weighing solution engineered for precision, long-term structural integrity, and operational reliability in demanding production, logistics, and quality control environments. Built upon a robust dual-layer frame architecture with low-profile geometry (90 mm deck-to-floor height), this platform scale employs load cell-based force measurement principles compliant with international metrological standards. Its core transduction system utilizes four high-stability alloy steel load cells—certified to OIML R60 Class C3 for accuracy class and rated for continuous industrial duty—ensuring repeatable static and dynamic mass measurements under variable environmental loads. The DF52XW3000WRZH variant features a 3000 kg capacity with 0.5 kg readability, optimized for medium-to-heavy industrial applications where mechanical durability and regulatory traceability are critical.
Key Features
- Structurally reinforced dual-layer platform: 6 mm checkered steel or stainless steel top deck (8 mm for 5000 kg models); U-shaped subframe formed from 4 mm cold-rolled steel or stainless steel plate, validated through 500,000 full-scale fatigue cycles per ISO 376 and internal OHAUS mechanical endurance protocols
- Four OIML R60 Class C3-certified alloy steel load cells; stainless steel variants equipped with hermetically sealed IP68-rated welded sensors for enhanced moisture and corrosion resistance
- IP65-rated all-stainless-steel junction box with integrated surge protection and terminal shielding for EMI/RFI immunity in electrically noisy facilities
- Low-profile design (90 mm deck clearance) facilitating seamless integration with pallet jacks, conveyors, and automated material handling systems
- Front-panel intuitive keypad with backlit LCD display, tactile feedback buttons, and programmable function keys for rapid mode switching
Sample Compatibility & Compliance
The DF52XW3000WRZH accommodates diverse industrial payloads including palletized goods, bulk containers, raw materials, and semi-finished assemblies. Its rigid platform geometry ensures stable center-of-gravity registration across irregularly shaped or dynamically loaded items. The scale complies with OIML R76-1 (Non-Automatic Weighing Instruments), meets CE marking requirements under the EU Measuring Instruments Directive (MID 2014/32/EU), and supports GLP/GMP documentation workflows via audit-trail-capable data export. Optional analog I/O (4–20 mA / 0–10 VDC) and discrete I/O (2-in / 4-out) enable direct interfacing with PLCs, SCADA systems, and automated packaging lines—facilitating compliance with ISA-88 and ISA-95 control architecture frameworks.
Software & Data Management
Standard RS232 serial interface enables bidirectional communication with PCs, label printers, and legacy industrial controllers using ASCII protocol. Optional connectivity modules support Ethernet TCP/IP, RS485 Modbus RTU, Bluetooth 5.0, and USB virtual COM port emulation—enabling integration into centralized MES or ERP platforms (e.g., SAP, Oracle). Firmware supports user-configurable data logging intervals, timestamped weight capture, and CSV/Excel-compatible output formats. All digital interfaces adhere to NIST Handbook 44 Appendix D guidelines for data integrity and may be configured to meet FDA 21 CFR Part 11 requirements when paired with validated third-party software solutions supporting electronic signatures and audit trails.
Applications
- Warehouse receiving and dispatch verification (inbound/outbound weight reconciliation)
- Manufacturing process control: batch weighing, ingredient verification, and fill-level monitoring
- Quality assurance: tolerance-based checkweighing for packaged goods (e.g., food, pharmaceuticals, automotive components)
- Inventory management: piece counting of uniform parts with automatic average-piece-weight calculation
- Logistics optimization: axle-load distribution analysis and trailer payload verification prior to transport
- Recycling and scrap metal operations: gross/net/tare weight tracking with configurable unit conversion
FAQ
What load cell certification does the DF52XW3000WRZH meet?
It uses OIML R60 Class C3-certified load cells, ensuring accuracy compliance for non-automatic weighing instruments used in trade and industrial applications.
Is the scale suitable for washdown environments?
Stainless steel variants feature IP68-rated hermetically sealed sensors and IP65-rated electronics; however, full washdown requires optional chemical-resistant gasketing and validation per EN 60529 and NSF/ANSI Standard 18.
Can the scale interface directly with a PLC?
Yes—via optional 4–20 mA analog output or discrete 2-in/4-out digital I/O, configurable through the onboard setup menu to trigger external actuators or signal status conditions.
Does the firmware support calibration traceability?
Yes—internal calibration log stores date/time stamps, operator ID (if enabled), and pre/post-calibration values, supporting ISO/IEC 17025-compliant laboratory quality systems.
What mounting accessories are available?
OHAUS-certified adjustable ramps (aluminum or galvanized steel), mobile castor kits with locking brakes, and floor anchor kits for seismic or high-vibration installations are available as factory-authorized options.
