Overview
The OHAUS Defender 5000 Series Heavy-Duty Platform Scale DF52P3000HRLZH 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 relies on four high-stability alloy steel load cells—certified to OIML R60 Class C3—and features stainless-steel welded hermetic sealing (IP68) for corrosion resistance in wet or washdown conditions. The scale’s mechanical design undergoes rigorous validation, including 500,000 full-scale fatigue cycles under certified test protocols, ensuring consistent repeatability and minimal creep error over extended service life.
Key Features
- Dual-layer reinforced frame construction with U-shaped base formed from 4 mm cold-rolled steel or stainless steel plate, providing exceptional torsional rigidity and load distribution uniformity.
- Heavy-duty weighing deck fabricated from 6 mm patterned steel plate or AISI 304 stainless steel (8 mm for 5-ton variants), optimized for slip resistance and impact resilience in high-traffic industrial settings.
- Four OIML R60 Class C3-certified load cells: alloy steel variants rated IP67; stainless-steel sealed variants rated IP68 for continuous operation in humid, dusty, or chemically aggressive environments.
- Hermetically sealed stainless-steel junction box rated IP65, protecting internal wiring and terminal connections against moisture ingress and particulate contamination.
- Low-profile design (90 mm deck height) minimizes loading/unloading effort and enhances ergonomic integration with pallet jacks, forklifts, and conveyor systems.
Sample Compatibility & Compliance
The DF52P3000HRLZH supports broad material handling compatibility—including palletized goods, bulk containers, drums, and irregularly shaped industrial loads—without requiring specialized fixtures. Its structural compliance aligns with OIML R76-1 (Non-Automatic Weighing Instruments), EN 45501, and ISO/IEC 17025 traceability requirements when used with calibrated reference masses. For regulated industries (e.g., food processing, pharmaceutical manufacturing, and chemical blending), the scale meets foundational hardware prerequisites for GLP/GMP documentation workflows. While the base unit does not include FDA 21 CFR Part 11-compliant audit trail functionality, its optional Ethernet and RS485 interfaces enable integration into validated SCADA or MES platforms where electronic record integrity is enforced at the system level.
Software & Data Management
The scale features a built-in RS232 serial interface as standard, supporting direct connection to label printers, PCs, or PLCs for real-time weight capture and basic data logging. Optional communication modules expand interoperability: dual RS232/RS485 ports support Modbus RTU master/slave configurations; USB and Ethernet interfaces enable TCP/IP-based integration with ERP or LIMS systems; Bluetooth 5.0 and Wi-Fi modules facilitate wireless telemetry in distributed warehouse environments. Analog I/O (4–20 mA / 0–10 VDC) and digital I/O (2-in / 4-out) options allow programmable control of external actuators—such as gates, conveyors, or fill valves—based on weight thresholds or status flags. All firmware updates and configuration parameters are managed via OHAUS’ proprietary ScaleLink utility software, which supports batch export in CSV/Excel format and time-stamped event logging.
Applications
- Warehouse receiving and dispatch verification, including inbound/outbound pallet weighing and tare management.
- In-process checkweighing in food, beverage, and packaging lines to ensure net weight compliance with regulatory labeling standards (e.g., EU Directive 2009/23/EC, NIST Handbook 133).
- Inventory reconciliation and raw material receipt in chemical, agricultural, and metal fabrication facilities.
- Dynamic weighing applications such as live animal weighing, drum filling control, and batch dispensing with hold-and-stabilize logic.
- Counting operations for uniform parts (e.g., fasteners, machined components) using sample-based piece-weight calibration.
FAQ
What is the maximum safe overload capacity of the DF52P3000HRLZH?
The scale is designed to withstand 150% of its rated capacity without permanent deformation or calibration shift, per OIML R76-1 Annex D mechanical safety requirements.
Can the scale be calibrated using external weights traceable to national standards?
Yes—it supports two-point linear calibration (zero and span) using certified test masses meeting ASTM E74 or ISO/IEC 17025 accreditation criteria.
Is the stainless-steel version suitable for outdoor installation?
While the IP68 load cells and IP65 junction box provide high environmental protection, prolonged exposure to UV radiation, salt spray, or freezing temperatures requires supplemental enclosure or sheltering per IEC 60529 environmental classification guidelines.
Does the scale support multiple user profiles with role-based access?
No—the base firmware does not include multi-user authentication; however, third-party SCADA or MES integration can enforce access control at the supervisory system layer.
What mounting options are available for permanent floor installation?
The unit includes pre-drilled anchor holes compatible with M12 concrete anchors; optional ramps (aluminum or galvanized steel) and mobile caster kits are available for flexible deployment across production zones.
