OHAUS Defender 5000 Series Heavy-Duty Platform Scale DF52XW5000WVZH

Overview

The OHAUS Defender 5000 Series Heavy-Duty Platform Scale DF52XW5000WVZH is an industrial-grade floor scale engineered for precision, durability, and long-term operational stability in demanding production, logistics, and quality control environments. Built upon a dual-layer structural architecture with a low-profile 90 mm platform-to-floor clearance, this scale integrates mechanical robustness with metrological reliability. Its measurement principle relies on high-linearity, temperature-compensated strain-gauge load cells operating under controlled excitation voltage and signal conditioning—ensuring consistent repeatability across wide ambient temperature ranges (–10 °C to +40 °C) and varying humidity conditions. The DF52XW5000WVZH meets international legal-for-trade requirements per OIML R60 Class C3 or C4 (depending on configuration), making it suitable for applications requiring traceable, auditable mass measurement in regulated manufacturing settings.

Key Features

• Dual-layer reinforced platform design featuring 6 mm textured carbon steel or 304 stainless steel top plate (8 mm for 5-ton capacity variants), providing enhanced resistance to impact, abrasion, and corrosion.
• U-shaped structural base fabricated from 4 mm cold-rolled steel or stainless steel sheet, validated through 500,000 full-scale fatigue cycles under laboratory-accredited testing protocols.
• Four high-stability alloy steel load cells compliant with OIML R60 C3 accuracy class; stainless steel models utilize hermetically sealed, laser-welded IP68-rated sensors for immersion-resistant operation in washdown or high-moisture areas.
• All-stainless-steel IP65-rated junction box with protected terminal blocks, enabling reliable signal integrity in dusty, humid, or chemically exposed industrial zones.
• Low-profile 90 mm deck height facilitates seamless integration with pallet jacks, conveyors, and automated material handling systems without ramp dependency.

Sample Compatibility & Compliance

The DF52XW5000WVZH accommodates standard industrial payloads—including palletized goods, bulk containers, drums, and machinery components—within its specified capacity range. Its rigid platform geometry minimizes deflection under off-center loading, maintaining ±0.02% of full scale linearity per OIML R76. The scale complies with electromagnetic compatibility standards EN 61326-1 (industrial environment) and safety standard EN 61010-1. For regulated industries, the device supports audit-ready operation when paired with OHAUS’s optional GLP/GMP-compliant software modules, including electronic signature support and 21 CFR Part 11–compatible data logging (when used with certified PC-based acquisition systems). Calibration certificates are available with NIST-traceable documentation upon request.

Software & Data Management

The integrated indicator supports real-time data transmission via standard RS232 serial interface, enabling direct communication with host PCs, label printers, PLCs, or MES systems. Optional connectivity modules extend functionality: RS485 enables multi-drop daisy-chaining over distances up to 1,200 m; Ethernet and Wi-Fi variants support TCP/IP-based integration into Industry 4.0 infrastructures. Analog outputs (4–20 mA / 0–10 VDC) allow direct interfacing with SCADA controllers or analog input cards, while programmable 2-in/4-out digital I/O permits external equipment triggering—e.g., activating gates, alarms, or reject mechanisms during checkweighing workflows. Firmware updates and parameter configuration are performed via USB or embedded web interface (Ethernet model), with configuration backups exportable in CSV format for version control and system recovery.

Applications

This platform scale serves critical roles across multiple sectors: incoming raw material verification and outgoing finished goods inspection in food & beverage processing; batch reconciliation and drum filling verification in chemical manufacturing; component counting and inventory reconciliation in automotive assembly; and dynamic pallet weighing in warehouse distribution centers. Its ruggedized construction and ingress protection ratings make it ideal for outdoor use in agricultural commodity grading, recycling facilities, and municipal waste management operations. When configured with optional ramps or mobile casters, the DF52XW5000WVZH adapts seamlessly to temporary staging areas or multi-location deployment scenarios without compromising calibration integrity.

FAQ

What certifications does the DF52XW5000WVZH hold for legal-for-trade use?

It conforms to OIML R60 Class C3/C4 and is type-approved for non-automatic weighing instruments under national metrological regulations in China (JJG 539). Certification for EU MID or US NTEP requires model-specific evaluation and local approval.
Can the scale be calibrated in-field without external service tools?

Yes—internal calibration routines support span and zero adjustment using certified test weights; full calibration reports with date/time stamps and operator ID are stored locally and exportable.
Is the stainless steel variant suitable for USDA-FSIS or EHEDG-certified food processing lines?

The IP68 load cells and fully welded stainless enclosure meet hygienic design principles for Zone 2 washdown environments; however, full compliance with EHEDG Doc. 8 or USDA sanitation protocols depends on installation method and surrounding facility validation.
Does the indicator support custom unit definitions or tare memory presets?

Up to 99 user-defined tare values and 20 configurable units (including kg, lb, oz, g, and custom ratios) can be programmed and recalled via alphanumeric keypad or remote command.
What is the maximum cable length supported for RS485 communication?

Up to 1,200 meters at 9,600 bps with proper twisted-pair cabling and termination resistors; longer runs require signal repeaters or fiber-optic media converters.
