OHAUS Defender 5000 Series Heavy-Duty Floor Scale DF52XW5000WXVZH

Overview

The OHAUS Defender 5000 Series Heavy-Duty Floor Scale DF52XW5000WXVZH is an industrial-grade platform scale engineered for precision, long-term stability, and operational resilience in demanding production, logistics, and quality control environments. Designed around a robust mechanical architecture and calibrated load cell technology, it operates on the principle of strain-gauge-based force transduction—where applied mass induces proportional deformation in high-strength alloy or stainless steel load cells, converted into digital weight readings via integrated signal conditioning and analog-to-digital conversion. Its low-profile 90 mm platform height minimizes loading effort while maintaining structural rigidity, and its dual-layer frame design—comprising a thick-textured top plate (6 mm standard, 8 mm for higher-capacity variants) and a reinforced U-shaped base formed from 4 mm cold-rolled steel or austenitic stainless steel—ensures dimensional stability under repeated heavy-duty use. All structural components undergo rigorous validation, including certified 500,000-cycle full-scale fatigue testing per ISO 376 and OIML R60 requirements.

Key Features

• Four OIML R60-certified alloy steel load cells (IP67 ingress protection); stainless steel variants feature hermetically welded IP68-rated sensors for enhanced corrosion resistance in washdown or high-humidity settings
• All-stainless-steel junction box rated IP65, ensuring reliable signal integrity and environmental resilience at the critical interface point between load cells and indicator
• Low-clearance platform (90 mm above floor level) optimized for pallet jack and forklift compatibility without compromising load-bearing integrity
• Structural frame fabricated from 4 mm precision-stamped steel or stainless steel; top surface available in textured carbon steel or electropolished stainless steel (304 or 316 grade options)
• Integrated overload protection and mechanical stop design compliant with OIML R76 and ANSI/NIST Handbook 44 Class III/III L performance criteria
• Indicator supports real-time calibration diagnostics, zero tracking, auto-zero stabilization, and programmable filtering for vibration-prone installations

Sample Compatibility & Compliance

The DF52XW5000WXVZH accommodates standard industrial containers—including pallets (up to 1200 × 1000 mm or 1200 × 800 mm), drums, tote bins, and bulk bags—without requiring platform modification. Its modular construction allows seamless integration into conveyor-fed checkweighing lines, warehouse receiving stations, and manufacturing workcells. From a regulatory standpoint, the scale meets OIML R60 (load cell accuracy class C3/C4), OIML R76 (non-automatic weighing instruments), and ANSI/NIST Handbook 44 specifications for Class III and III L applications. The stainless steel configuration complies with FDA 21 CFR Part 11 data integrity prerequisites when used with audit-trail-enabled software, and supports GLP/GMP documentation workflows through traceable calibration records and user-access logging (when paired with compatible OHAUS SmartConnect software).

Software & Data Management

The built-in indicator supports native RS232 communication for direct connection to PCs, label printers, or PLCs. Optional interface modules enable secure, long-range data transmission via RS485 (up to 1,200 m), Ethernet (TCP/IP), or Bluetooth 5.0 (up to 30 m line-of-sight). Analog I/O (4–20 mA / 0–10 VDC) and discrete digital I/O (2-in/4-out) allow direct integration with SCADA systems, programmable logic controllers, and automated gates or reject mechanisms. When connected to OHAUS SmartConnect software (Windows/macOS), users gain access to configurable data logging, CSV/Excel export, statistical process control (SPC) charting, and electronic signature support aligned with 21 CFR Part 11 Annex 11 expectations. Audit trails capture timestamped events—including calibration, tare, unit change, and mode selection—for full traceability in regulated environments.

Applications

• Warehouse inbound/outbound receiving and pallet verification
• In-line checkweighing for food, pharmaceutical, and chemical packaging lines
• Raw material intake and batch reconciliation in process manufacturing
• Inventory management and cycle counting in distribution centers
• Dynamic weighing of moving loads on roller conveyors (with optional hold-and-capture logic)
• Counting operations for uniform parts (e.g., fasteners, machined components, vials)
• Percentage weighing for formulation and blending tasks in R&D or pilot-scale production

FAQ

What is the maximum permissible error (MPE) for this scale under OIML R76?
Per OIML R76-1:2021, the DF52XW5000WXVZH is classified as a Class III instrument; MPE is ±0.5e for 0 ≤ m ≤ 500e, ±1.0e for 500e < m ≤ 2000e, and ±1.5e for 2000e < m ≤ Max, where 'e' denotes verification scale interval.

Can the scale be calibrated using external weights traceable to NIST or BIPM standards?
Yes—the indicator supports multi-point linear calibration with certified test weights traceable to national metrology institutes, and stores calibration coefficients with date/time stamps and operator ID when configured with SmartConnect.

Is the stainless steel version suitable for outdoor installation?
The IP68 load cells and IP65-rated indicator provide high resistance to dust and water ingress, but extended outdoor exposure requires additional sheltering against UV degradation, thermal drift, and condensation-induced zero drift; ambient operating temperature range is –10 °C to +40 °C.

Does the system support integration with SAP or Oracle ERP platforms?
Via Ethernet or RS485 interfaces and ODBC-compatible SmartConnect output, weight data can be mapped to ERP fields using middleware or custom API connectors compliant with RFC 2616 (HTTP/1.1) or RFC 7231 (RESTful conventions).
