OHAUS Defender 5000 Series Heavy-Duty Floor Scale DF52P3000HLXZH

Overview

The OHAUS Defender 5000 Series Heavy-Duty Floor Scale DF52P3000HLXZH is an industrial-grade platform scale engineered for precision, durability, and long-term operational stability in demanding production, warehousing, logistics, and agricultural environments. Built upon a robust dual-layer structural architecture with reinforced U-channel base framing, this floor scale employs load cell-based force measurement principles compliant with international metrological standards. Its design integrates mechanical rigidity with electronic accuracy—leveraging strain-gauge technology to convert applied mass into proportional electrical signals, which are then processed via high-resolution A/D conversion and temperature-compensated digital filtering. The DF52P3000HLXZH variant is configured for high-capacity static weighing applications, supporting nominal capacities up to 3,000 kg (6,614 lb) with verified repeatability and linearity performance suitable for routine QC checks, inbound/outbound material verification, and process control tasks under ISO/IEC 17025-aligned laboratory or factory-floor conditions.

Key Features

• Structurally reinforced platform: 6 mm chequered steel or stainless-steel top plate (8 mm for 5,000 kg models), supported by 4 mm U-channel base frame formed from cold-rolled steel or AISI 304 stainless steel—validated through 500,000 full-scale fatigue cycles per OIML R76 requirements.
• Low-profile installation: Platform height of only 90 mm above floor level, minimizing ramp requirements and facilitating pallet jack integration.
• Four OIML R60-certified alloy steel load cells (IP67 ingress protection); stainless-steel variants utilize hermetically welded IP68 load cells with laser-welded housings and internal moisture barriers.
• IP65-rated all-stainless-steel junction box with corrosion-resistant terminals and sealed cable entries.
• Modular connectivity: Standard RS232 interface for local PC or thermal printer communication; optional expansion modules include Bluetooth 5.0, dual RS232/RS485, USB Device/Host, Ethernet (TCP/IP), and analog I/O (4–20 mA / 0–10 VDC) or digital I/O (2-in / 4-out) for PLC interfacing and external device control.

Sample Compatibility & Compliance

The DF52P3000HLXZH accommodates standard industrial payloads including palletized goods, drums, crates, and bulk containers—compatible with common forklifts, hand trucks, and automated guided vehicles (AGVs). Its structural geometry supports uniform load distribution across the entire platform surface, minimizing edge-loading errors. The scale complies with OIML R76 (Non-Automatic Weighing Instruments), EN 45501, and ANSI/NIST Handbook 44 Class III specifications. Load cell certification meets OIML R60 C3 or C4 accuracy classes. For regulated environments, firmware supports audit-trail logging and user-access controls compatible with GLP/GMP documentation workflows. Optional firmware upgrades enable 21 CFR Part 11-compliant electronic signatures and data integrity safeguards when integrated with validated software systems.

Software & Data Management

The built-in indicator features embedded firmware supporting six core weighing modes: Static Weighing, Checkweighing, Piece Counting, Percentage Weighing, Dynamic Weighing (with configurable filter settings), and Hold Mode for unstable loads. All weight data—including timestamps, operator IDs, and mode selections—is stored internally with configurable retention periods. Via RS232 or optional Ethernet, raw data streams can be exported in ASCII or CSV format to LIMS, MES, or ERP platforms using standard protocols (e.g., Modbus RTU/TCP). Third-party software integration is facilitated through OHAUS’s open API documentation and SDK packages, enabling custom dashboard development and real-time weight monitoring dashboards. Firmware updates are performed via USB flash drive or network download, with version rollback and integrity checksum verification.

Applications

This floor scale serves as a primary weighing node in manufacturing quality gates (e.g., pre-shipment inspection, batch reconciliation), warehouse receiving docks (inbound pallet verification), agricultural commodity grading (grain, feed, fertilizer), and recycling facility sorting lines (metal scrap, plastic bales). Its low-profile design and rugged construction make it suitable for wet or dusty environments—common in food processing plants (when specified with stainless-steel components), chemical handling zones, and outdoor storage yards. When paired with optional ramps or mobile stands, it supports flexible deployment across multiple workstations without permanent anchoring.

FAQ

What certifications does the DF52P3000HLXZH hold for legal-for-trade use?

It meets OIML R76 requirements for non-automatic weighing instruments and carries national type approval in China (NIM certification); trade-use validation requires local verification per national metrology regulations.
Can the scale interface directly with a PLC system?

Yes—via optional 4–20 mA analog output or 2-in/4-out digital I/O module, enabling direct start/stop signaling, pass/fail relay actuation, and status feedback to industrial controllers.
Is calibration traceable to NIST or other international standards?

Internal calibration is supported using certified test weights; external calibration services provided by accredited third-party labs offer NIST-traceable certificates upon request.
What environmental conditions is the scale rated for?

Operating temperature range: –10 °C to +40 °C; relative humidity: ≤90 % RH (non-condensing); IP65 enclosure rating for indicator, IP67 (or IP68 for stainless variants) for load cells.
Does the scale support multi-language display?

Firmware includes English, Spanish, French, German, and Simplified Chinese language options, configurable via on-screen menu.
