Overview
The OHAUS Defender 5000 Series Heavy-Duty Platform Scale DF52P600HSZH is an industrial-grade weighing solution engineered for precision, long-term mechanical stability, and operational resilience in demanding production, logistics, and quality control environments. Built upon a robust dual-layer structural architecture, the scale employs load cell-based force measurement principles compliant with international metrological standards for static and dynamic mass determination. Its design prioritizes mechanical integrity under repeated high-cycle loading—validated through 500,000 full-capacity fatigue cycles per OIML R76 and ISO/IEC 17025-aligned test protocols—ensuring consistent repeatability and minimal drift across shifts and seasonal temperature variations. The low-profile 90 mm ground clearance enables seamless integration into conveyor lines, palletizing stations, and warehouse workflows without requiring structural modification.
Key Features
- Structural integrity: 6 mm checkered steel or stainless-steel top plate (8 mm for 5-ton variants); U-shaped base frame formed from 4 mm cold-rolled steel or AISI 304 stainless steel via precision stamping and welding
- Load sensing system: Four OIML R60-certified alloy steel load cells (IP67 ingress protection); stainless-steel variants utilize hermetically sealed IP68 welded sensors with laser-welded housings
- Enclosure rating: IP65-rated all-stainless-steel junction box; optional IP67-rated terminal housing available for washdown environments
- Low-profile platform: 90 mm deck-to-floor height optimized for pallet jack and forklift compatibility
- Modular connectivity: Standard RS232 interface for local PC or thermal printer communication; optional expansion modules include Bluetooth 5.0, dual RS232/RS485, USB-C, Ethernet (TCP/IP), 4–20 mA / 0–10 VDC analog outputs, and 2-in/4-out digital I/O for PLC integration
Sample Compatibility & Compliance
The DF52P600HSZH accommodates standard industrial containers—including Euro pallets (1200 × 800 mm), CHEP pallets (1200 × 1000 mm), and custom crates—within its nominal platform dimensions. Its mechanical and electrical design conforms to OIML R76 (non-automatic weighing instruments), EN 45501, and NTEP Class III certification requirements (where applicable). The stainless-steel variant meets FDA-compliant surface finish standards (Ra ≤ 0.8 µm) and supports cleaning validation per ISO 14644-1 Class 8 cleanroom protocols. All firmware and calibration routines comply with ISO/IEC 17025 traceability requirements, and audit trails support GLP/GMP documentation workflows when paired with OHAUS SmartLink software.
Software & Data Management
The scale operates with OHAUS SmartLink v3.2 firmware, supporting configurable data logging intervals (1–3600 s), CSV export via USB or network, and real-time weight streaming to MES/SCADA systems. Optional SmartLink Pro license enables 21 CFR Part 11-compliant user authentication, electronic signatures, and immutable audit trails—including timestamped event logs for calibration, zeroing, unit changes, and parameter modifications. Data transmission adheres to IEEE 802.3 Ethernet standards (10/100BASE-TX) and Modbus TCP register mapping for seamless SCADA integration. Local memory retains ≥10,000 weight records with time/date stamps, even during network outages.
Applications
- Static weighing of raw materials, finished goods, and returnable packaging in automotive, food processing, and chemical manufacturing
- In-line checkweighing with programmable upper/lower tolerance bands for compliance with ISO 2859-1 AQL sampling plans
- Parts counting using calibrated sample weights, with statistical reporting of count accuracy (±0.2% typical at >100 units)
- Percentage weighing relative to a reference tare—commonly used in batching, formulation, and additive dosing
- Dynamic weighing mode with hold-and-display function for unstable loads on vibrating floors or conveyors
- Integration with automated gates, light towers, and reject mechanisms via digital I/O or analog control signals
FAQ
What certifications does the DF52P600HSZH hold for legal-for-trade use?
It meets OIML R76 Class III requirements and carries NTEP Certificate of Conformance (CoC) for Class III applications in North America. Regional approvals (e.g., MID in EU) require model-specific configuration and local verification.
Can the scale be calibrated internally without external weights?
Yes—internal calibration is supported via built-in motorized calibration mechanism (optional) or electronic calibration using stored reference values traceable to NIST or BIPM standards.
Is the stainless-steel version suitable for outdoor installation?
The IP68 sensor housing and IP65-rated terminal provide resistance to rain, dust, and incidental splashing, but prolonged UV exposure and condensation require supplemental canopy or enclosure per IEC 60529 Annex B guidelines.
How is firmware updated in field-deployed units?
Firmware updates are performed via USB flash drive or over-the-air (OTA) using signed .bin files authenticated via RSA-2048 signature verification to prevent unauthorized modification.
Does the scale support multi-language UI and regulatory unit definitions?
Yes—12 preloaded languages (including English, Spanish, German, Chinese, Japanese) and configurable unit sets aligned with ASTM E691, ISO 80000, and national metrology regulations.
