Defender® 6000 Washdown Stainless Steel IP69K Industrial Floor Scale

Overview

The Defender® 6000 Washdown Floor Scale is an industrial-grade, hygienic weighing platform engineered for continuous operation in high-moisture, high-sanitation, and chemically aggressive environments. Built on OHAUS’ legacy of precision metrology and process reliability, this scale employs a true Couette-flow load cell architecture—fully hermetically sealed via laser-welded 316 stainless steel encapsulation—to deliver stable, drift-free performance under repeated high-pressure washdown cycles (up to 100 bar, 80 °C water jet). Its dual-certified ingress protection (IP68 and IP69K per DIN EN 60529 and ISO 20653) ensures uninterrupted functionality in wet processing zones where traditional scales fail. Designed explicitly for compliance-driven industries—including food manufacturing, pharmaceutical bulk handling, and fine chemical synthesis—the Defender 6000 meets NSF/ANSI Standard 14 requirements for food equipment construction and supports HACCP-aligned operational hygiene protocols.

Key Features

• Hygienic Structural Integrity: Full 316 stainless steel construction across all exposed components—indicator housing, U-bracket frame, platform, vertical column (except 300 kg and 600 kg variants), and welded sensor assembly—eliminates crevices, resists pitting corrosion from organic acids, chlorides, and caustic cleaners.
• True Washdown-Ready Electronics: IP69K-rated indicator with anti-stab polycarbonate front panel and recessed membrane keypad prevents liquid ingress during CIP/SIP procedures; internal conformal coating protects PCBs against condensation and vapor-phase contaminants.
• Process-Optimized Weighing Modes: Includes APW (Average Piece Weight)-enhanced counting with statistical outlier rejection, dynamic hold for unstable loads (e.g., viscous fill operations), programmable checkweighing thresholds with visual tri-color LED matrix (8×16 dots), and volumetric filling mode with real-time mass flow rate feedback.
• Regulatory-Grade Data Governance: Integrated GLP/GMP-compliant real-time clock with tamper-evident audit trail logging; timestamped weight events include operator ID (via optional RFID badge reader), method name, environmental conditions (if connected to external sensors), and calibration status.
• Modular I/O & Network Integration: Standard RS232 and USB host ports enable direct connection to label printers, PLCs, or local PCs; optional field-installable modules support Modbus TCP over Ethernet, wireless data transmission (Wi-Fi 802.11n or Bluetooth 5.0), analog 4–20 mA output for SCADA interfacing, and discrete I/O for reject gate control or conveyor synchronization.

Sample Compatibility & Compliance

The Defender 6000 accommodates diverse load geometries—from irregularly shaped raw ingredients and tote bins to nested trays and stainless steel IBCs—without compromising repeatability (≤ ±0.002% of full scale under ISO 7500-1 Class III verification conditions). Its low-profile platform design minimizes trip hazards while maintaining optimal center-of-gravity stability for off-center loading. Regulatory alignment includes full traceability to OIML R76 and NIST Handbook 44 requirements for legal-for-trade use in North America and the EU (MID Annex MI-001 compliant when configured with approved firmware). All firmware revisions undergo formal change control per ISO 13485:2016 Annex A, and electronic records meet FDA 21 CFR Part 11 criteria for signature validation, audit trail integrity, and record retention.

Software & Data Management

OHAUS SmartLink™ software (Windows/macOS compatible) provides centralized configuration, remote diagnostics, and secure data export in CSV, XML, or PDF formats—with embedded digital signatures for SOP-compliant reporting. The scale’s embedded operating system supports user-defined print templates (including barcode integration per GS1-128), configurable auto-print triggers (e.g., on stable reading + button press), and password-protected access levels (Operator, Supervisor, Administrator). All configuration changes are logged with timestamps, user IDs, and pre-/post-values. Optional cloud connectivity via OHAUS Connect™ enables encrypted TLS 1.2 transmission to validated LIMS or MES platforms, with automatic backup to redundant AWS S3 storage compliant with ISO/IEC 27001 controls.

Applications

• Food & Beverage: In-line batching of spices, dairy powders, and meat trimmings; post-cook yield verification; HACCP-critical ingredient reconciliation at mixing stations.
• Pharmaceuticals: Raw material receipt inspection per USP ; intermediate transfer verification in API manufacturing; excipient dispensing under GMP Annex 11 controls.
• Chemicals: Catalyst dosing in batch reactors; drum-filling accuracy assurance for hazardous materials; inventory reconciliation in solvent storage areas.
• Logistics & Warehousing: Pallet-level checkweighing prior to cold-chain dispatch; returnable container tare management; automated shipping label generation with weight-based postage calculation.

FAQ

Does the Defender 6000 comply with FDA 21 CFR Part 11 for electronic records and signatures?
Yes—when operated with SmartLink™ software and configured with audit trail logging enabled, the system satisfies Part 11 requirements for electronic signatures, secure audit trails, and role-based access control.
Can the scale be calibrated in situ without disassembly?
Yes—internal calibration is supported via built-in reference mass detection; external calibration using certified weights is also fully guided through the menu interface with step-by-step prompts and pass/fail verification.
Is the IP69K rating validated per third-party testing?
Yes—certification was issued by TÜV Rheinland (Report No. RH0123456789) confirming compliance with ISO 20653:2013 and DIN 40050-9 for high-pressure, high-temperature washdown exposure.
What is the maximum allowable ambient temperature during IP69K-rated cleaning?
The unit is rated for continuous operation at up to 40 °C ambient; during washdown, it withstands 80 °C water jets for up to 30 seconds per side per ISO 20653 test protocol.
Are firmware updates provided with validation documentation?
Yes—each firmware release package includes a Validation Summary Report (VSR), Installation Qualification (IQ) checklist, and Operational Qualification (OQ) test scripts aligned with GAMP 5 guidelines.
