Overview
The OHAUS Defender 3000 i-D33XW is an industrial-grade waterproof platform scale engineered for reliable performance in demanding production, packaging, food processing, and pharmaceutical manufacturing environments. Built upon OHAUS’ legacy of precision weighing instrumentation, this scale employs electromagnetic force compensation (EMFC) technology within a hermetically sealed, IP67-rated stainless steel load cell—ensuring long-term stability and repeatability under repeated exposure to moisture, cleaning agents, and mechanical stress. Its fully welded 304 stainless steel construction—including the indicator housing, pan, base frame, and internal structural components—meets rigorous hygiene standards for facilities operating under FDA-regulated, GMP, or HACCP-compliant workflows. The i-D33XW model is specifically calibrated for medium-capacity applications (e.g., 60 kg capacity with 10 g readability), supporting deterministic process control where environmental resilience and metrological integrity are non-negotiable.
Key Features
- Full 304 stainless steel construction across all exposed and structural components—pan, base, indicator enclosure, and load cell housing—enabling compatibility with high-pressure washdown, caustic sanitizers, and steam cleaning cycles.
- IP66-rated indicator with multicolor backlight LCD (45 mm digit height): real-time visual feedback via red/yellow/green illumination during checkweighing—eliminating operator interpretation delay and reducing human error in line-side quality verification.
- Dual-power architecture: integrated rechargeable lead-acid battery (up to 80 hours runtime) and universal 110–240 VAC input—supporting uninterrupted operation during power fluctuations or mobile deployment across production zones.
- Tactile membrane keypad with sealed actuation—designed for gloved operation and resistant to ingress of particulates, liquids, and cleaning residues.
- Four preconfigured operational modes: standard weighing, parts counting (with automatic average piece weight calculation), dynamic checkweighing with configurable tolerance bands, and accumulation for batch totalization—all accessible without menu navigation.
- Standard RS232 serial interface for direct connection to label printers, PLCs, or legacy MES systems; optional USB or Ethernet modules enable integration into modern IIoT architectures with TCP/IP-based data logging and remote configuration.
Sample Compatibility & Compliance
The i-D33XW accommodates diverse industrial sample forms—including packaged goods, bulk containers, tote bins, and raw material batches—without compromising accuracy or structural integrity. Its low-profile, reinforced pan design minimizes center-of-gravity shift during off-center loading, maintaining NTEP Class III and OIML R76 compliance for legal-for-trade applications in North America and EU markets. The scale’s construction adheres to ISO 14644-1 (cleanroom-compatible surface finish), EN 60529 (IP66/IP67 validation), and FDA 21 CFR Part 11 readiness when paired with OHAUS LoggerPro™ software for audit-trail-enabled data capture. It is routinely deployed in USDA-inspected meat processing lines, dairy filling stations, and contract manufacturing organizations subject to annual GLP/GMP audits.
Software & Data Management
While the i-D33XW operates autonomously via its embedded firmware, it supports seamless bidirectional data exchange through standardized ASCII protocols over RS232. When connected to OHAUS LoggerPro™ (v4.0+), users gain access to time-stamped, user-authenticated data export (CSV/Excel), electronic signature support, and configurable alarm logging—fulfilling ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available). Optional Ethernet connectivity enables integration with SCADA systems or cloud-based dashboards via Modbus TCP, supporting Industry 4.0 traceability requirements without middleware dependency.
Applications
- Food & Beverage: In-line checkweighing of filled pouches, trays, and cartons prior to case packing; ingredient batching in wet-processing areas.
- Pharmaceutical Manufacturing: Weighing of primary packaging components (blister cards, vials) in cleanroom-adjacent staging zones.
- Chemical & Plastics: Dispensing of polymer pellets or additive masterbatches under humid or solvent-exposed conditions.
- Logistics & Warehousing: Palletized load verification in refrigerated or outdoor dock environments.
- Contract Manufacturing: Multi-client production lines requiring rapid reconfiguration between regulatory regimes (e.g., FDA vs. Health Canada).
FAQ
Is the i-D33XW certified for legal-for-trade use in the United States?
Yes—the scale is NTEP Class III approved and stamped for commercial applications where weight determines price or regulatory compliance.
Can the indicator be mounted remotely from the scale base?
Yes—its modular design supports wall-mounting, pole-mounting, or bench-top placement using the included stainless steel U-bracket; cable length is 2 m (extendable up to 5 m with shielded RS232 extension).
Does the load cell require recalibration after repeated washdown cycles?
No—IP67 sealing and 304 stainless construction prevent moisture-induced drift; however, periodic verification using traceable test weights per ASTM E74 is recommended as part of a site’s calibration management program.
What data security features are available for audit compliance?
When used with LoggerPro™ and Ethernet option, the system logs user ID, timestamp, action type, and value change—meeting FDA 21 CFR Part 11 requirements for electronic records and signatures.
Is firmware update supported in-field?
Yes—updates are delivered via USB stick or Ethernet; version history and checksum validation ensure integrity and traceability per ISO/IEC 17025 clause 5.9.4.
