Overview
The OHAUS Defender 5000 Series Heavy-Duty Platform Scale DF52XW1500WLXZH is an industrial-grade weighing system engineered for precision, durability, and operational reliability in demanding production, logistics, and quality control environments. Built upon a robust mechanical architecture and compliant with international metrological standards, this platform scale employs load cell-based force measurement—specifically utilizing four high-stability alloy steel load cells (stainless steel variant features hermetically sealed IP68 weldments)—to convert mechanical deformation into calibrated electrical signals. The scale operates under the principle of electromagnetic force compensation for zero stability and thermal drift mitigation, ensuring long-term repeatability and minimal calibration drift across variable ambient conditions. With a low-profile 90 mm deck-to-floor height and dual-layer structural framing, it supports seamless integration into conveyor lines, palletizing stations, and warehouse workflows where floor clearance and structural integrity are critical.
Key Features
- Heavy-duty construction: 6 mm checkered steel or stainless steel top deck (8 mm for 5-ton variants); U-shaped subframe formed from 4 mm cold-rolled steel or stainless steel plate, validated through 500,000 full-scale fatigue cycles per OIML R76 requirements
- Four OIML R60-certified alloy steel load cells (IP67 rated); stainless steel model equipped with IP68 hermetically welded load cells for enhanced corrosion resistance
- IP65-rated all-stainless steel junction box with protected terminal blocks and moisture-resistant gasketing
- Low-profile design: 90 mm overall height enables flush mounting with conveyors and minimal ramp incline requirements
- Integrated overload protection and mechanical shock absorption to preserve sensor integrity during impact loading
- Front-panel tactile keypad with backlit LCD display for operation under low-light or dusty industrial conditions
Sample Compatibility & Compliance
The DF52XW1500WLXZH accommodates standard industrial payloads including palletized goods, drums, crates, and bulk containers up to its rated capacity. Its rigid deck geometry and optimized load distribution ensure accurate weighing regardless of load placement within the active weighing area—verified per OIML R76 Class III performance criteria. The scale meets CE marking requirements for non-automatic weighing instruments (NAWI Directive 2014/31/EU) and conforms to IP65 (enclosure) and IP67 (load cells) ingress protection ratings per IEC 60529. Optional configurations support ATEX Zone 21 compliance for dust-explosive environments when specified with appropriate enclosure and cabling. All firmware and hardware design elements align with ISO/IEC 17025 traceability frameworks for metrological validation and GLP/GMP audit readiness.
Software & Data Management
The scale features embedded firmware supporting multiple communication protocols via standardized interfaces. RS232 is standard for direct connection to label printers, PCs, or PLCs; optional modules include RS485 (for multi-drop networks), Ethernet (TCP/IP), Bluetooth 5.0 (Class 1), and USB Device/Host modes. Analog I/O (4–20 mA / 0–10 VDC) and digital I/O (2-in / 4-out) enable programmable control of external actuators, alarms, or sorting gates without external PLC intervention. Data logging supports time-stamped weight records with user-defined metadata fields. Firmware supports configurable audit trails compliant with FDA 21 CFR Part 11 requirements—including electronic signatures, event logging, and data immutability safeguards—when deployed with OHAUS Sentinel™ software suite or third-party MES/ERP systems via OPC UA or Modbus TCP.
Applications
This platform scale serves as a foundational metrology node across diverse industrial verticals: incoming raw material verification in food processing plants; dynamic checkweighing of packed goods on high-speed packaging lines; inventory reconciliation in automotive assembly warehouses; drum filling control in chemical manufacturing; and scrap metal yield monitoring in recycling facilities. Its structural resilience and environmental sealing make it suitable for outdoor weighbridges (with proper foundation and weather shielding), wet-process areas in beverage bottling, and abrasive-dust environments in cement or mineral processing. Integration-ready I/O and protocol flexibility allow deployment in Industry 4.0 architectures—feeding real-time weight data into SCADA dashboards, predictive maintenance algorithms, or automated batch release logic.
FAQ
What is the maximum permissible error (MPE) for this scale under OIML R76 Class III?
Per OIML R76-1:2021, MPE is ±0.5e for loads ≤50% of max capacity and ±1.0e for loads >50% of max capacity, where ‘e’ denotes verification scale interval.
Can the scale be calibrated using external weights traceable to NIST or BIPM standards?
Yes—calibration follows ISO 9001 Annex A.3 procedures and supports two-point linear calibration with certified test masses meeting ASTM E74 or ISO/IEC 17025 accreditation requirements.
Is firmware update capability available over network interfaces?
Firmware updates are supported via USB flash drive or Ethernet (TFTP/HTTP), with checksum validation and rollback functionality to ensure integrity.
Does the scale support automatic tare subtraction during continuous weighing operations?
Yes—tare memory retains up to 10 user-defined tare values, and auto-tare can be triggered by proximity sensor input or timed intervals.
Are explosion-proof versions available for hazardous locations?
ATEX-certified variants (II 2D Ex tb IIIC T135°C Db IP66) are available upon request with custom engineering review and documentation package.
