Overview
The OHAUS Defender 5000 Series Heavy-Duty Platform Scale DF52P1500HRZH is an industrial-grade weighing solution engineered for precision, durability, and operational reliability in demanding production, logistics, and quality control environments. Utilizing load cell-based force measurement technology, the scale delivers high reproducibility under dynamic and static loading conditions across a wide range of ambient temperatures and humidity levels. Its structural architecture integrates mechanical robustness with metrological integrity—designed to meet the long-term stability requirements of continuous-duty applications in agriculture, manufacturing, warehousing, and material handling. The DF52P1500HRZH variant features a 1500 kg capacity with high-resolution readability (typically 0.1–0.2 kg depending on configuration), optimized for heavy-load weighing where repeatability and resistance to mechanical shock are critical.
Key Features
- Heavy-duty dual-layer platform construction: 6 mm checkered steel or stainless-steel top plate (8 mm for 5-ton models), supported by a U-shaped subframe formed from 4 mm cold-rolled steel or stainless-steel sheet—validated through 500,000 full-scale fatigue cycles per OIML R76 and internal mechanical endurance protocols.
- Four high-stability alloy steel load cells compliant with OIML R60 Class C3 (IP67 rated); stainless-steel variants employ hermetically sealed, laser-welded IP68 load cells for enhanced corrosion resistance in washdown or humid environments.
- IP65-rated all-stainless-steel junction box with integrated terminal block and surge protection—designed for compatibility with industrial electrical noise environments.
- Low-profile design: 90 mm platform-to-floor height minimizes ramp requirements and improves operator ergonomics during palletized or cart-based loading.
- Modular connectivity: Standard RS232 interface supports direct connection to label printers, PCs, or PLCs; optional interfaces include wireless (Bluetooth 5.0), dual RS232/RS485, USB, Ethernet (TCP/IP), and analog I/O (4–20 mA / 0–10 VDC) or digital I/O (2-in / 4-out) for integration into automated control systems.
Sample Compatibility & Compliance
The DF52P1500HRZH accommodates diverse load geometries—including pallets, drums, crates, and irregularly shaped industrial containers—without compromising accuracy. Its rigid platform geometry ensures minimal deflection under off-center loading (tested per OIML R76 Annex D). The scale complies with international legal-for-trade requirements where certified configurations are deployed, including OIML R76 (Class III), NTEP Certificate of Conformance (for U.S. commercial use), and EU Measuring Instruments Directive (MID) Annex MI-001 when equipped with appropriate firmware and calibration documentation. All stainless-steel variants meet ISO 14644-1 Class 8 cleanroom compatibility thresholds for surface particulate generation and are suitable for food-grade (FDA 21 CFR Part 110) and pharmaceutical (cGMP Annex 11) auxiliary weighing tasks when operated within documented procedures.
Software & Data Management
The built-in indicator firmware supports configurable data logging (up to 1,000 entries), time-stamped weight records, and user-defined batch identifiers. When connected via RS232 or Ethernet, the scale integrates seamlessly with OHAUS ACIS™ (Advanced Communication Interface Software) for real-time data streaming, SPC charting, and audit-trail-enabled export to CSV, Excel, or SQL databases. Optional firmware upgrades enable 21 CFR Part 11-compliant electronic signatures, role-based access control, and GLP/GMP-aligned audit trails—including operator ID, timestamp, weight value, unit, and mode (e.g., “checkweigh”, “counting”)—ensuring traceability in regulated quality management systems.
Applications
- Manufacturing: In-line component verification, raw material receipt inspection, and finished goods pallet weighing prior to shipment.
- Agriculture & Feed Processing: Bulk grain, fertilizer, or livestock feed batching with percentage-based formulation and tolerance-based pass/fail evaluation.
- Logistics & Distribution Centers: Loading dock verification, parcel aggregation, and dimensional weight validation for freight billing.
- Recycling & Scrap Metal Facilities: Accurate mass determination of ferrous/non-ferrous scrap loads under variable environmental exposure.
- Food & Beverage Production: Dry ingredient dispensing, tray/packaging tare compensation, and HACCP-critical weight checks at critical control points.
FAQ
Is the DF52P1500HRZH approved for legal-for-trade use in the United States?
Yes—when configured with NTEP-certified load cells and firmware, it meets NTEP Handbook 44 requirements for Class III applications up to 1500 kg.
Can the scale be calibrated in the field without external service tools?
Yes—it supports internal calibration using factory-programmed reference weights and offers guided calibration routines accessible via the front-panel menu.
What mounting options are available for permanent installation?
Optional bolt-down kits, adjustable leveling feet, and reinforced concrete anchor plates are available; mobile configurations support caster-mounted stands with integrated brakes.
Does the scale support integration with MES or ERP systems?
Yes—via Ethernet or RS485 Modbus RTU/ASCII protocol, enabling bi-directional communication with SAP, Oracle, or custom SCADA platforms.
How is overload protection implemented mechanically and electronically?
Mechanical stoppers limit platform displacement beyond ±150% of rated capacity; firmware includes programmable over-limit alarms, automatic zero-tracking suspension, and error-code logging for diagnostic traceability.
