OHAUS Defender 5000 Series Heavy-Duty Platform Scale DF52XW3000WLXZH

Overview

The OHAUS Defender 5000 Series Heavy-Duty Platform Scale DF52XW3000WLXZH is an industrial-grade weighing solution engineered for precision, durability, and long-term reliability in demanding production, logistics, and quality control environments. Built upon a robust dual-layer structural architecture with low-profile geometry (90 mm deck-to-floor height), this platform scale employs load cell-based force measurement principles—specifically, strain-gauge transduction calibrated per OIML R60 Class C3 or C4 accuracy requirements—to deliver stable, repeatable static and dynamic mass readings under variable operational loads. Its design prioritizes mechanical integrity over aesthetic minimalism: the load-bearing surface consists of 6 mm patterned steel or stainless-steel plate (8 mm for 5-ton configurations), while the U-shaped subframe is formed from 4 mm cold-rolled steel or austenitic stainless steel, validated through 500,000 full-capacity fatigue cycles per ISO 376 and ASTM E74 protocols.

Key Features

• Structural resilience: 6 mm (or 8 mm for ≥5 t models) textured carbon steel or 304 stainless-steel deck; 4 mm press-formed U-frame with reinforced gusseting for torsional rigidity
• High-integrity load sensing: Four OIML R60-compliant alloy-steel load cells (IP67 rated); stainless-steel variants feature hermetically welded IP68 sensors with laser-welded housings
• Environmental protection: IP65-rated all-stainless-steel junction box; optional IP67/IP68 enclosure upgrades available for washdown or outdoor deployment
• Low-profile ergonomics: 90 mm deck height minimizes loading effort and enables seamless integration with conveyors, pallet jacks, and automated material handling systems
• Modular connectivity: Standard RS232 interface for local data logging or printer interfacing; optional expansion modules support RS485, USB, Ethernet, Bluetooth 5.0, or wireless 2.4 GHz transmission
• Process integration capability: Optional analog I/O (4–20 mA / 0–10 VDC) and digital I/O (2-in / 4-out) for PLC synchronization, relay control, or external device triggering

Sample Compatibility & Compliance

The DF52XW3000WLXZH accommodates standard industrial containers—including Euro pallets (1200 × 800 mm), ISO pallets (1200 × 1000 mm), and custom skids—without requiring recalibration. Its mechanical design complies with EN 45501 for non-automatic weighing instruments and meets electromagnetic compatibility requirements per EN 61326-1. Load cell certification adheres to OIML R60 Class C3 (for general industrial use) or C4 (for high-precision applications), with verification traceable to national metrology institutes (NMI) via factory calibration certificates. The scale supports GLP/GMP-aligned operation when used with optional audit-trail-enabled software and password-protected parameter configuration.

Software & Data Management

While the DF52XW3000WLXZH operates autonomously via its integrated alphanumeric display and tactile keypad, it interfaces seamlessly with OHAUS ACIS™ (Advanced Control & Integration Software) for centralized fleet management, calibration history tracking, and user-access logging. When connected via RS232 or Ethernet, real-time weight data can be exported to SQL databases, MES platforms (e.g., Siemens Opcenter, Rockwell FactoryTalk), or ERP systems (SAP, Oracle). Optional firmware updates enable 21 CFR Part 11-compliant electronic signatures, role-based access control, and immutable audit trails for regulated manufacturing environments.

Applications

• Static weighing of raw materials, finished goods, and returnable transport items in food processing, pharmaceutical bulk handling, and automotive assembly lines
• Dynamic checkweighing for inline quality assurance—paired with photoelectric sensors to reject out-of-tolerance packages
• Parts counting in electronics component distribution centers using pre-calibrated unit-weight libraries
• Percentage weighing for formulation tasks in chemical blending and additive dosing operations
• Legal-for-trade applications in municipal waste transfer stations and agricultural cooperatives where NTEP or MID certification is required (subject to regional model variant)
• Integration into automated guided vehicle (AGV) docking stations for payload verification prior to dispatch

FAQ

Is the DF52XW3000WLXZH certified for trade use in the United States or EU?
This model may be configured for legal-for-trade operation; however, final certification (NTEP Certificate of Conformance or MID approval) depends on regional calibration and approval by authorized bodies—contact your local OHAUS representative for jurisdiction-specific variants.
Can the scale be installed outdoors?
Yes, when specified with IP67/IP68 load cells, stainless-steel construction, and optional weatherproof enclosure, it is suitable for covered outdoor installations with temperature ranges from –10 °C to +40 °C.
What is the maximum recommended sampling rate for dynamic weighing?
The internal A/D converter supports up to 10 Hz stable output under nominal load; optimal dynamic accuracy is achieved at ≤5 Hz for moving loads on roller conveyors.
Does the scale support multi-language display?
Yes—firmware versions include English, Spanish, French, German, Chinese, and Japanese UI options, configurable via menu navigation.
How is calibration performed and documented?
Internal span and zero calibration are supported; external calibration requires certified test weights traceable to SI units. Calibration events are timestamped and stored in non-volatile memory with operator ID logging when ACIS™ is deployed.
