OHAUS Defender 3000 i-D33P Industrial Platform Scale

Overview

The OHAUS Defender 3000 i-D33P is an industrial-grade platform scale engineered for reliability, readability, and operational flexibility in demanding production, warehousing, logistics, and quality control environments. Built upon OHAUS’ legacy of precision weighing instrumentation, the i-D33P implements a robust mechanical architecture—featuring a square-tube carbon steel frame with electrostatic powder coating, a corrosion-resistant 304 stainless steel weighing pan, and an IP65-rated aluminum load cell—to ensure long-term stability under repeated loading cycles and ambient exposure to dust and non-corrosive moisture. Its core measurement principle relies on electromagnetic force compensation (EMFC)-derived strain gauge transduction, calibrated per OIML R76 and ASTM E74 standards, delivering consistent repeatability (< ±0.002% of full scale) across temperature ranges from 10 °C to 40 °C. Designed explicitly for dry-industrial settings—not laboratory or hazardous locations—the scale meets essential regulatory expectations for traceability and functional safety in GMP-aligned manufacturing workflows.

Key Features

• Large-format, 6-digit, 7-segment multicolor backlit LCD display with 45 mm digit height—optimized for legibility at distances up to 3 meters under variable lighting conditions including high-ambient glare.
• Three-color visual checkweighing feedback (red/yellow/green) directly mapped to user-defined tolerance bands—enabling immediate go/no-go decisions without operator interpretation delay.
• Dual-power architecture: integrated rechargeable sealed lead-acid battery (up to 60 hours runtime) plus universal AC input (110–240 VAC, 50/60 Hz), supporting uninterrupted operation during power fluctuations or mobile deployment.
• Modular mounting system with adjustable U-shaped metal bracket and optional wall/pole/tabletop configurations—facilitating rapid repositioning across assembly lines, packing stations, or inventory docks.
• Tactile membrane keypad with haptic feedback—designed for gloved-hand operation and resistant to particulate ingress and cleaning agents commonly used in food-grade or pharmaceutical adjacent facilities.

Sample Compatibility & Compliance

The i-D33P is rated for static weighing of solid, non-fluid industrial items—including packaged goods, components, palletized loads (with compatible deck), and bulk materials in containers—within its 150 kg capacity and 10 g readability range. It is not intended for dynamic weighing, animal weighing, or applications requiring legal-for-trade certification in regulated markets (e.g., retail pricing). The device complies with CE marking requirements under the EU Measuring Instruments Directive (MID) Annex MI-001 for non-automatic weighing instruments (NAWI), RoHS 2011/65/EU for hazardous substance restriction, and is manufactured in an ISO 9001:2015-certified facility in Shanghai, China. While not certified to NTEP or EC Type Evaluation, its mechanical and electrical design aligns with foundational elements of ISO/IEC 17025:2017 clause 5.5 (equipment verification) for in-house calibration validation.

Software & Data Management

The i-D33P supports bidirectional ASCII-based data exchange via its standard RS232 serial interface—compatible with label printers (e.g., Zebra GK420t), PLCs, and legacy MES systems using Modbus RTU or custom ASCII protocols. Optional USB (virtual COM port) or Ethernet (TCP/IP socket) modules enable integration into modern IIoT architectures, supporting periodic weight logging to SQL databases or cloud platforms via middleware such as Node-RED or OPC UA gateways. All firmware updates are performed offline via SD card (not included), preserving data integrity during maintenance. Audit trail functionality is not embedded; however, external systems may capture timestamped weight events with source identification when configured with appropriate network logging policies.

Applications

• Production line checkweighing of pre-packed consumer goods (e.g., bottles, cartons, blister packs) against upper/lower mass limits.
• Inventory reconciliation via piece counting mode—calibrated using sample batches to minimize counting error (5 g).
• Shipping manifest verification: accumulation of sequential weights for pallet or tote loading verification prior to dispatch.
• Raw material receipt inspection in automotive, electronics, or packaging supply chains where batch-level mass consistency is critical.
• Internal quality assurance audits requiring documented weight records traceable to equipment ID and operator logins (when interfaced with host systems).

FAQ

Is the i-D33P suitable for use in wet or washdown environments?

No. While the load cell carries an IP65 rating, the indicator housing is rated NEMA 4X-equivalent only—not IP67 or higher. It must be operated in dry, indoor industrial spaces free of direct water contact or high-humidity condensation.
Does this scale support internal calibration or require external weights?

It features internal span calibration using factory-stored reference values; no external weights are required for routine recalibration. However, verification with traceable test masses is recommended per ISO/IEC 17025 clause 5.5.2 at defined intervals.
Can the checkweighing thresholds be customized per product SKU?

Yes. Up to 100 user-defined checkweighing profiles can be stored locally on the indicator, each with independent target mass, tolerance bands, and associated color logic.
Is FDA 21 CFR Part 11 compliance supported?

No. The i-D33P does not include electronic signature, audit trail, or role-based access control features. For regulated pharmaceutical or biotech applications, consider OHAUS’s ADVENTURER PRO series with validated software options.
What is the warranty coverage and service support structure?

OHAUS provides a 2-year limited warranty covering parts and labor for defects in materials or workmanship. Global technical support and authorized service centers are accessible through OHAUS regional offices—no third-party repair authorization is granted.
