Overview
The OHAUS Defender 5000 Series Heavy-Duty Platform Scale DF52XW3000WXVZH is an industrial-grade weighing system engineered for precision, durability, and long-term operational stability in demanding production, logistics, and quality control environments. Built upon OHAUS’ legacy of metrological rigor, this platform scale employs a robust dual-layer structural architecture with load transmission optimized through four high-reliability alloy steel load cells—certified to OIML R60 Class C3 (or stainless-steel welded IP68 variants for corrosive or washdown settings). Its low-profile design—only 90 mm from platform surface to floor—facilitates seamless integration into conveyor lines, palletizing stations, and material handling workflows without requiring structural modification. The scale operates on the fundamental principle of strain-gauge-based load measurement, where mechanical deformation of the sensing elements under applied mass is converted into proportional millivolt signals, digitized and compensated for temperature drift, nonlinearity, and eccentric loading via embedded firmware algorithms compliant with international weighing standards.
Key Features
- Dual-layer reinforced platform construction: 6 mm checkered steel or stainless-steel top plate (8 mm for 5-ton configurations), supported by 4 mm U-channel base frame formed via precision stamping and stress-relieved welding
- Four OIML R60 Class C3-certified alloy steel load cells (IP67 rated); stainless-steel variants feature hermetically sealed IP68 welded sensors for enhanced environmental resilience
- IP65-rated all-stainless-steel junction box with corrosion-resistant terminals and modular cable routing
- Low-clearance footprint: 90 mm overall height enables flush mounting with standard pallet jacks and roller conveyors
- Validated for 500,000 full-scale fatigue cycles per ASTM E74 and ISO 376 protocols, ensuring consistent repeatability over extended service life
- Integrated overload protection and shock-absorbing feet to mitigate impact damage during dynamic loading
Sample Compatibility & Compliance
The DF52XW3000WXVZH accommodates a wide range of industrial samples—from bulk raw materials and packed goods to assembled components and palletized shipments—without requiring sample preparation or containment. Its large platform area supports standard Euro pallets (1200 × 800 mm) and industrial skids. The scale complies with OIML R76-1 (2021), EN 45501:2015, and meets essential requirements for use in legally regulated trade applications when verified and stamped by national metrology institutes. For GMP/GLP-regulated facilities, optional audit-trail-enabled firmware and user-access-controlled calibration logs support compliance with FDA 21 CFR Part 11 and EU Annex 11 requirements. All stainless-steel configurations meet USDA and EHEDG hygiene guidelines for food processing environments.
Software & Data Management
The built-in indicator features a programmable RS232 interface as standard, enabling direct ASCII data streaming to PCs, label printers, or PLCs using industry-standard protocols (e.g., Modbus RTU over RS485 via optional module). Optional communication interfaces include Bluetooth 5.0, dual RS232/RS485, USB host/device, Ethernet (TCP/IP), and analog I/O (4–20 mA / 0–10 VDC output + 2 digital inputs / 4 digital outputs) for real-time process interlocking. OHAUS ScaleConnect™ software (Windows/macOS) provides configuration backup, firmware updates, statistical reporting (mean, SD, CV%), and customizable print templates compatible with common thermal and dot-matrix printers. All data transfers are timestamped and traceable; optional secure authentication ensures role-based access control for calibration and parameter adjustment.
Applications
- Warehouse receiving and outbound verification: gross/net/tare weight capture with barcode-triggered auto-recall
- Manufacturing line checkweighing: real-time pass/fail feedback against configurable tolerance bands
- Inventory management: piece counting mode with automatic average piece weight (APW) calculation and drift compensation
- Batch formulation and ingredient dispensing: percentage weighing relative to reference mass for compound blending
- Dynamic weighing of moving loads on roller conveyors (with optional hold-and-display stabilization)
- Recycling and scrap metal yards: durable construction resists abrasion, impact, and outdoor exposure
FAQ
What is the maximum permissible error (MPE) for this model at full capacity?
Per OIML R76-1, MPE is ±0.5e for Class III applications, where ‘e’ denotes verification scale interval—specific values depend on final configuration and local verification authority requirements.
Can the scale be calibrated in-house without external certification?
Yes—internal calibration is supported via front-panel menu; however, initial verification and periodic legal-for-trade recalibration must be performed by an accredited metrology laboratory.
Is the indicator compatible with ERP/MES systems like SAP or Oracle?
Yes—via RS232/RS485 or Ethernet, using custom ASCII framing or Modbus TCP mapping; OHAUS provides protocol documentation and integration support.
Does the stainless-steel version meet FDA or NSF standards for food contact?
The 304 stainless-steel platform and load cell housing comply with FDA 21 CFR 178.3570 and NSF/ANSI Standard 2 for food equipment surfaces; full system certification requires site-specific validation.
What environmental conditions does the IP67 rating cover?
IP67 indicates dust-tight ingress protection and resistance to temporary immersion in water up to 1 m depth for 30 minutes—suitable for wet processing floors, cold storage, and outdoor deployment with proper sheltering.
