OHAUS Defender 3000 i-D33XW Waterproof Floor Scale

Overview

The OHAUS Defender 3000 i-D33XW is an industrial-grade, full-stainless-steel floor scale engineered for reliable operation in demanding wet, dusty, or hygienically sensitive production environments. Built on OHAUS’s legacy of robust weighing instrumentation, this scale employs electromagnetic force restoration (EMFR) load cell technology—optimized for stability under thermal fluctuation and mechanical vibration—ensuring consistent repeatability across extended operational cycles. Its structural architecture complies with the mechanical and environmental requirements of food processing, pharmaceutical manufacturing, chemical blending, and logistics staging zones where frequent cleaning with high-pressure water jets or caustic sanitizers is standard practice. The integrated indicator features a sealed front panel and conformal-coated internal circuitry, enabling continuous use in ambient conditions ranging from –10 °C to +40 °C and relative humidity up to 90 % non-condensing.

Key Features

• Full 304 stainless steel construction—including indicator housing, platform, support frame, and load cell—provides corrosion resistance against chlorinated cleaners, organic acids, and saline exposure.
• IP66-rated indicator and IP67-rated hermetically sealed load cell meet IEC 60529 standards for protection against powerful water jets and temporary submersion.
• 6-digit, 7-segment multicolor backlit LCD display with 45 mm character height ensures legibility under low-light factory lighting, overhead glare, or protective eyewear.
• Three-color checkweighing feedback (red/yellow/green) enables immediate visual pass/fail assessment without operator interpretation—reducing human error in packaging line verification.
• Dual power architecture supports uninterrupted operation: auto-switching between AC mains (110–240 VAC, 50/60 Hz) and internal rechargeable sealed lead-acid battery (up to 80 hours runtime at typical usage).
• Four primary operating modes—Standard Weighing, Piece Counting, Checkweighing, and Accumulation—are accessible via tactile membrane keys designed for gloved-hand actuation.

Sample Compatibility & Compliance

The i-D33XW accommodates bulk materials, packaged goods, tote bins, and palletized loads within its rated capacity range (model-specific; consult datasheet for exact max load). Its flat, seamless stainless-steel platform minimizes trapping points for particulate or microbial contamination—supporting compliance with FDA 21 CFR Part 11 (when paired with validated data capture software), EU GMP Annex 11, and ISO/IEC 17025 traceability frameworks. The scale is routinely deployed in facilities certified to ISO 22000, BRCGS Food Safety, and SQF Level 3, where documented equipment qualification (IQ/OQ/PQ) and periodic calibration against NIST-traceable standards are mandatory.

Software & Data Management

Data output follows ASCII protocol over RS232 serial interface (standard), enabling direct integration with label printers (e.g., Zebra, Sato), PLCs, MES systems, and ERP platforms such as SAP EWM or Oracle WMS. Optional USB or Ethernet modules support TCP/IP-based communication, facilitating centralized configuration management and remote firmware updates. When connected to OHAUS’s optional EasyView™ or third-party compliant software (e.g., LabWare LIMS, METTLER TOLEDO LabX), the scale supports audit trail generation, user access control, electronic signature capture, and automatic timestamped record archiving—all aligned with ALCOA+ principles for data integrity.

Applications

• Food & Beverage: In-line checkweighing of filled trays, pouches, or crates prior to metal detection and case packing.
• Pharmaceuticals: Raw material receipt verification, batch ingredient dispensing, and intermediate product accumulation in non-sterile manufacturing areas.
• Chemicals: Precise batching of catalysts, pigments, or polymer additives where moisture-induced drift must be minimized.
• Logistics & Warehousing: Pallet tallying, load consolidation verification, and returnable container reconciliation under variable ambient conditions.
• Contract Manufacturing: Multi-client production lines requiring rapid reconfiguration between weight-based SOPs without recalibration.

FAQ

What is the ingress protection rating of the indicator and load cell?
The indicator meets IP66 per IEC 60529 (dust-tight and protected against powerful water jets); the load cell is rated IP67 (dust-tight and withstands immersion up to 1 m for 30 minutes).
Does the scale support GLP/GMP-compliant data recording?
Yes—when interfaced with validated software supporting 21 CFR Part 11, it provides electronic signatures, audit trails, and immutable data export.
Can the display backlight color logic be customized per application?
No—the red/yellow/green thresholds are fixed in firmware but programmable via numeric setpoints for upper/lower limits and tolerance bands.
Is calibration traceable to national standards?
Yes—OHAUS provides optional NIST-traceable calibration certificates (ISO/IEC 17025 accredited) upon request, with documented uncertainty budgets.
What maintenance intervals are recommended for long-term accuracy?
Daily visual inspection and weekly functional verification with certified test weights are advised; full recalibration every 6–12 months depending on usage frequency and environmental stress.
