Overview
The OHAUS Defender 5000 Series Heavy-Duty Platform Scale DF52XW3000WRLZH is an industrial-grade weighing solution engineered for precision, durability, and operational reliability in demanding production, logistics, and quality control environments. Based on electromagnetic force compensation and high-stability load cell transduction principles, this platform scale delivers consistent static and dynamic weight measurement across a wide range of material handling applications—from raw material intake and in-process batching to finished goods palletizing and shipping verification. Its structural architecture integrates mechanical robustness with metrological integrity: the low-profile 90 mm deck height minimizes loading effort while maintaining rigidity; the U-shaped base frame, formed from 4 mm thick carbon steel or stainless steel plate, provides torsional resistance under off-center or eccentric loads; and the reinforced top deck—6 mm (or 8 mm for 5-ton variants) chequered steel or stainless steel—ensures long-term surface stability and slip resistance. Designed for continuous operation in industrial settings, the DF52XW3000WRLZH meets fundamental requirements for repeatability, linearity, and temperature-induced drift mitigation per OIML R76 and ISO 9001-aligned manufacturing practices.
Key Features
- Four high-reliability alloy steel load cells compliant with OIML R60 Class C3 (IP67 rated); stainless steel variant features IP68 hermetically sealed welded sensors
- Full stainless steel junction box rated IP65, corrosion-resistant and suitable for washdown environments
- Low-profile 90 mm deck-to-floor height enables seamless integration with conveyors, pallet jacks, and manual handling equipment
- Double-layer rigid frame construction with integrated stress-relieved mounting geometry to minimize creep and hysteresis
- Validated for 500,000 full-scale fatigue cycles—certified by independent third-party testing per ISO 376 and ASTM E74 protocols
- Integrated overload protection and mechanical stop design to safeguard sensor integrity during accidental overloading
Sample Compatibility & Compliance
The DF52XW3000WRLZH supports broad sample compatibility across bulk solids, packaged goods, containers, and palletized loads—up to its rated capacity (model-specific). Its ruggedized enclosure and ingress protection meet IP65 (electronics housing) and IP67/IP68 (sensor assembly), making it suitable for humid, dusty, or intermittently wet industrial zones. The scale complies with international metrological standards including OIML R76-1 (non-automatic weighing instruments), EN 45501 (European harmonized standard for industrial scales), and ANSI/NIST Handbook 44 (U.S. legal-for-trade requirements where certified variants are deployed). While not inherently 21 CFR Part 11 compliant, audit-ready data logging and user-access controls can be implemented via optional software integration for GLP/GMP-aligned workflows.
Software & Data Management
Standard RS232 serial interface enables direct connection to PCs, label printers, or PLCs for real-time weight capture and basic data export. Optional communication modules extend functionality: dual RS232/RS485 ports support multi-device daisy-chaining; Ethernet or Bluetooth/Wi-Fi adapters enable remote monitoring and centralized fleet management; analog I/O (4–20 mA / 0–10 VDC) and digital I/O (2-in / 4-out) allow programmable control of external actuators, alarms, or sorting gates. OHAUS AC-POWER™ software (sold separately) provides configurable data logging, statistical process control (SPC) charting, batch reporting, and CSV/Excel export—fully traceable with timestamped operator ID and event logs. All firmware updates follow secure signed-package protocols to ensure system integrity.
Applications
- Static weighing of drums, totes, crates, and palletized shipments in warehousing and distribution centers
- Checkweighing and tolerance-based rejection in food, pharmaceutical, and automotive component assembly lines
- Counting operations for uniform parts (e.g., fasteners, connectors, tablets) using calibrated piece-weight methodology
- Dynamic weighing and hold-mode display for unstable or settling loads (e.g., live animals, viscous materials)
- Percentage weighing relative to tare reference for formulation, blending, and additive dosing tasks
- Integration into automated packaging lines via I/O-triggered start/stop or pass/fail signal output
FAQ
Is the DF52XW3000WRLZH certified for trade use?
This model is built to OIML R76 and EN 45501 specifications; however, legal-for-trade certification requires local verification and stamping by national metrology authorities (e.g., NIST, PTB, or NMi). Contact your regional OHAUS representative for certified variants.
Can the scale be used outdoors?
It is rated IP65/IP67 for dust and water resistance but is not designed for prolonged exposure to UV radiation, freezing temperatures, or direct rainfall without shelter or enclosure.
What calibration options are available?
Internal calibration is supported via built-in weight simulation; external calibration with certified test weights (Class M1 or better) is recommended annually or after mechanical impact, per ISO/IEC 17025 guidelines.
Does it support multiple user profiles?
Yes—when paired with AC-POWER™ software, role-based access control (administrator/operator) and activity audit trails are fully configurable.
Are ramps or mobile stands included?
No—these are optional accessories; OHAUS offers standardized aluminum ramps (DF-RAMP series) and heavy-duty castor-mounted stands (DF-STAND series) compatible with all Defender 5000 platform models.
