OHAUS Defender® DF52P5000HVZH Heavy-Duty Platform Scale

Overview

The OHAUS Defender® DF52P5000HVZH is a high-capacity, industrial-grade platform scale engineered for precision, durability, and operational continuity in demanding production, logistics, and quality control environments. Built upon the proven Defender 5000 platform architecture, this model integrates structural robustness with metrological reliability—leveraging four OIML R60–certified load cells to deliver consistent force-to-mass conversion across its full rated capacity. The scale operates on the principle of strain-gauge transduction: mechanical deformation of alloy steel or stainless steel sensing elements under load generates proportional electrical resistance changes, which are digitized and processed by the integrated weighing indicator. Its low-profile 90 mm platform height minimizes loading effort while maintaining structural integrity through a dual-layer frame design—featuring a 6 mm (or 8 mm for 5-ton configurations) textured steel or stainless steel top plate and a 4 mm U-shaped base frame formed via high-precision stamping. All structural components undergo certified fatigue validation—500,000 full-scale load cycles—to ensure long-term repeatability and zero-point stability under continuous industrial use.

Key Features

• Structural resilience validated to 500,000 full-capacity load cycles per OIML R60 fatigue requirements
• Dual-layer platform construction: 6 mm (or 8 mm) textured steel/stainless steel deck bonded to a 4 mm stamped U-frame for torsional rigidity and impact resistance
• Four OIML R60–certified load cells: alloy steel variants rated IP67; stainless steel welded variants rated IP68 for washdown and corrosive environments
• IP65-rated all-stainless-steel junction box with sealed cable entries and corrosion-resistant terminals
• Low-clearance 90 mm platform height enabling seamless integration with pallet jacks, conveyors, and manual handling workflows
• Modular interface architecture supporting both legacy and modern data infrastructure: standard RS232, plus optional Ethernet, RS485, USB, Bluetooth, analog (4–20 mA / 0–10 VDC), and digital I/O (2-in / 4-out)

Sample Compatibility & Compliance

The DF52P5000HVZH accommodates diverse industrial payloads—from palletized goods and bulk containers to raw material batches and assembled components—without requiring recalibration between load types. Its wide, stable platform ensures uniform load distribution across all four load cells, minimizing eccentric-loading error. The scale complies with OIML R60 Class C3 (for general industrial use) and meets electromagnetic compatibility (EMC) requirements per EN 61326-1. Stainless steel configurations satisfy hygiene-critical applications aligned with FDA 21 CFR Part 11 data integrity expectations when paired with compliant software systems. While the scale itself does not embed audit-trail functionality, its digital interfaces support traceable data export to LIMS or MES platforms operating under GLP/GMP frameworks.

Software & Data Management

The integrated indicator supports bidirectional RS232 communication for real-time weight streaming, batch ID logging, and command-driven mode switching (e.g., toggling between checkweighing and counting). Optional Ethernet or USB connectivity enables direct integration with Windows-based host applications—including OHAUS ACSS (Advanced Communication Software Suite)—for automated report generation, SPC charting, and database synchronization. Analog and digital I/O ports allow hardware-level process interlocking: e.g., triggering reject gates upon out-of-tolerance weight detection or activating fill-stop signals in batching operations. All data transmission adheres to ASCII protocol standards; no proprietary encryption or closed firmware is employed—ensuring interoperability with third-party SCADA and IIoT edge gateways.

Applications

• Manufacturing line checkweighing for packaged goods compliance (e.g., pharmaceutical secondary packaging, food retail units)
• Raw material receipt verification and inventory reconciliation in chemical, agricultural, and metal fabrication facilities
• In-process batch weighing during mixing, compounding, or formulation stages
• Logistics hub pallet weighing with dynamic hold function for unstable or settling loads
• Scrap metal and recyclables sorting stations requiring ruggedized, corrosion-resistant weighing surfaces
• Warehouse receiving docks where low-profile access and rapid throughput are critical

FAQ

What environmental protection ratings apply to the DF52P5000HVZH?

The load cells are rated IP67 (alloy steel) or IP68 (stainless steel); the junction box is IP65. The indicator housing rating depends on configuration but typically meets IP54 or higher.
Is calibration traceable to national standards?

Yes—when calibrated using NIST-traceable weights and following OHAUS-recommended procedures, results comply with ISO/IEC 17025–accredited laboratory practices.
Can the scale interface with ERP or MES systems?

Yes, via optional Ethernet, RS485, or USB modules, enabling direct data ingestion into SAP, Oracle, or custom MES platforms using standard ASCII or Modbus RTU protocols.
Does it support legal-for-trade certification?

OIML R60 Class C3 certification is factory-verified; local type approval (e.g., NTEP, MID) requires jurisdiction-specific verification and sealing by authorized metrology bodies.
What mounting accessories are available?

OHAUS-certified ramps (aluminum or galvanized steel), mobile floor stands with locking casters, and adjustable leveling feet kits are available as factory-authorized options.
