OHAUS Defender® DF52P5000HXZH Heavy-Duty Platform Scale

Overview

The OHAUS Defender® DF52P5000HXZH is a high-capacity, industrial-grade platform scale engineered for precision, durability, and long-term reliability in demanding production, logistics, and quality control environments. Built upon OHAUS’ proven Defender 5000 series architecture, this model employs load cell-based force measurement technology—specifically, four high-stability alloy steel load cells (stainless steel variant features hermetically sealed IP68 weldments)—to convert mechanical load into calibrated electrical signals with high linearity and repeatability. Its low-profile 90 mm deck-to-floor height and dual-layer structural frame optimize ergonomics and integration into assembly lines, palletizing stations, or warehouse receiving bays. Designed to meet the mechanical and metrological requirements of routine industrial weighing tasks—including gross/net/tare operations, dynamic load monitoring, and process feedback—the DF52P5000HXZH complies with international weighing standards for non-automatic weighing instruments under OIML R76 and supports verification per OIML R60 for load cell accuracy class C3.

Key Features

• Robust dual-layer structural design: 6 mm chequered steel or stainless steel top deck (8 mm for 5-ton configurations); U-shaped base frame formed from 4 mm cold-rolled steel or stainless steel plate, validated through 500,000 full-scale fatigue cycles
• Four OIML R60-certified C3-class load cells—alloy steel (IP67-rated) or fully welded stainless steel (IP68-rated)—ensuring thermal stability, creep resistance, and long-term zero-point retention
• IP65-rated all-stainless steel junction box with protected terminal blocks and moisture-resistant cable glands
• Low-clearance installation: 90 mm overall height enables seamless integration with conveyors, pallet jacks, and floor-level material handling systems
• Modular connectivity architecture supporting RS232 (standard), plus optional RS485, USB, Ethernet, Bluetooth, or wireless modules for SCADA, MES, or ERP integration
• Configurable analog I/O (4–20 mA / 0–10 VDC) and digital I/O (2-in / 4-out) for direct interface with PLCs, relays, or automated gates

Sample Compatibility & Compliance

The DF52P5000HXZH accommodates irregularly shaped, heavy, or palletized loads up to its rated capacity (model-specific; consult datasheet for exact range). Its rigid deck surface—available in corrosion-resistant stainless steel or abrasion-tolerant chequered carbon steel—supports repeated impact from forklifts, pallet trucks, and bulk containers without deformation. The scale meets IP65 environmental protection for the indicator and IP67/IP68 for load cells, enabling operation in humid, dusty, or washdown-prone areas typical of food processing, chemical manufacturing, and agricultural facilities. It supports traceable calibration per ISO/IEC 17025-accredited procedures and is compatible with GLP/GMP documentation workflows when paired with compliant software. While not certified for legal-for-trade use in all jurisdictions without local verification, it satisfies preliminary conformity assessment criteria under EU Directive 2014/31/EU (NAWI) and ANSI/NIST Handbook 44 for Class III applications.

Software & Data Management

The integrated indicator firmware supports bidirectional data exchange via ASCII protocol over RS232, enabling direct logging to Windows-based PCs or label printers. Optional communication modules allow secure, time-stamped data transmission to centralized databases using TCP/IP or Modbus RTU/TCP. Audit-trail functionality—including user login tracking, parameter change logs, and calibration event timestamps—is available when configured with OHAUS SmartLink™ or third-party SCADA-compatible middleware. All firmware updates are delivered via signed binary packages to ensure integrity; no proprietary cloud dependency is required for core operation. Data export formats include CSV and fixed-width text, facilitating import into LIMS, SAP QM, or custom QA dashboards.

Applications

• Warehouse inbound/outbound verification: pallet weight validation, shipment consolidation, and container loading checks
• Manufacturing process control: batch ingredient verification, drum filling, and component kitting with tolerance-based pass/fail output
• Agricultural commodity trading: grain, feed, or fertilizer bagging with count-by-weight and percentage deviation reporting
• Recycling and scrap metal operations: gross/tare reconciliation across heterogeneous loads
• Heavy equipment maintenance: axle load distribution analysis and counterweight balancing
• Education and vocational training labs: demonstration of static/dynamic weighing principles, sensor signal conditioning, and industrial I/O interfacing

FAQ

Is the DF52P5000HXZH approved for trade use in the United States or European Union?

It is supplied as a Class III industrial scale and requires local verification and stamping by an authorized metrology body (e.g., NIST Handbook 44 Field Inspection or EU notified body) prior to legal-for-trade deployment.
Can the scale operate reliably in outdoor or high-humidity environments?

Yes—the IP67/IP68 load cells and IP65 indicator provide robust protection against dust ingress and temporary water immersion; however, prolonged exposure to direct rainfall or corrosive vapors necessitates additional shelter or stainless-steel configuration.
Does the system support 21 CFR Part 11-compliant electronic records?

Native Part 11 compliance is not embedded in the indicator firmware; however, when integrated with validated third-party data acquisition software featuring audit trails, electronic signatures, and role-based access control, full compliance can be achieved within a documented quality system.
What calibration documentation is provided with the scale?

Each unit ships with a factory calibration certificate traceable to NIST or equivalent national metrology institute (NMI), including as-found/as-left data, sensitivity, linearity, and repeatability test results at multiple points across the span.
Are mounting ramps or mobile stands available as certified accessories?

Yes—OHAUS offers OEM-designed, load-rated steel ramps and adjustable-height mobile stands, each engineered to maintain structural integrity and metrological performance under full-scale dynamic loading conditions.
