OHAUS Defender 3000 i-D33P Industrial Platform Scale

Overview

The OHAUS Defender 3000 i-D33P is an industrial-grade platform scale engineered for reliability and operational clarity in demanding production, warehousing, logistics, and quality control environments. Built upon OHAUS’ legacy of precision weighing instrumentation, the i-D33P implements a robust load cell architecture—featuring an IP65-rated aluminum sensing element—integrated with a rigid square-tube carbon steel frame and a corrosion-resistant 304 stainless steel weighing pan. Its measurement principle relies on electromagnetic force compensation (EMFC)-optimized strain gauge technology calibrated to deliver high reproducibility under variable load conditions typical of dynamic floor-scale applications. Designed explicitly for dry industrial settings—not wet, washdown, or hazardous locations—the scale meets foundational metrological requirements for non-automatic weighing instruments per OIML R76-1 (Class III) and supports traceable calibration protocols aligned with ISO/IEC 17025-accredited laboratories.

Key Features

• Multi-color backlit LCD display (45 mm digit height) with tri-state checkweighing indicators (red/yellow/green) enabling immediate visual pass/fail assessment without operator interpretation delay.
• Industrial-grade mechanical keypad with tactile feedback optimized for gloved-hand operation and long-term durability in high-cycle environments.
• Dual-power architecture: integrated rechargeable lead-acid battery (up to 80 hours runtime) and universal AC input (110–240 VAC, 50/60 Hz), ensuring uninterrupted operation during power fluctuations or mobile deployment.
• Modular mounting system with adjustable U-shaped metal bracket allows wall, benchtop, or pedestal installation—adapting to spatial constraints in packaging lines, loading docks, or inventory staging zones.
• Four core application modes: standard weighing, parts counting (with auto-average sample weight calculation), dynamic checkweighing (with configurable upper/lower limits and tolerance bands), and accumulation (batch totalization across multiple weighments).
• Robust mechanical construction: powder-coated square-tube steel frame resists impact and torsional stress; 304 stainless steel pan withstands abrasion, chemical exposure, and repeated cleaning cycles.

Sample Compatibility & Compliance

The i-D33P accommodates discrete solid items—including packaged goods, components, palletized loads up to 60 kg, and bulk containers—within ambient temperature ranges of 10–40 °C and relative humidity ≤80 % RH (non-condensing). It is not rated for use with liquids, powders requiring containment, or materials generating electrostatic discharge. As a Class III non-automatic weighing instrument per OIML R76-1, it conforms to European CE marking directives (2014/30/EU EMC, 2014/35/EU LVD), RoHS 2011/65/EU, and is manufactured under ISO 9001-certified quality management systems. While not intrinsically certified for FDA 21 CFR Part 11 or GLP/GMP environments, its RS232 data output supports integration into validated workflows when paired with compliant software and audit-trail-enabled host systems.

Software & Data Management

Data capture is facilitated through a standard RS232 serial interface (configured at 9600 baud, 8N1), compatible with label printers, PLCs, and legacy MES/ERP terminals. Optional USB (HID or virtual COM mode) and Ethernet (TCP/IP) interfaces enable direct connectivity to Windows-based QC software, database logging tools, or cloud-based inventory platforms. The indicator does not embed onboard data storage or user-accessible firmware updates; instead, it functions as a deterministic real-time I/O node—ensuring deterministic latency and eliminating firmware-related drift risks. All communication protocols are ASCII-based and fully documented in the OHAUS Communication Protocol Manual (Rev. D), supporting custom scripting for automated data ingestion and statistical process control (SPC) feed.

Applications

The i-D33P serves critical roles across manufacturing and distribution operations: verifying fill weights in primary and secondary packaging lines; performing piece-count verification for electronic components, fasteners, or pharmaceutical blister packs; executing inbound/outbound checkweighing against shipping manifests; aggregating batch totals during kitting or assembly staging; and supporting lean manufacturing initiatives such as Kanban replenishment and cycle count auditing. Its tri-color visual feedback reduces cognitive load during high-volume sorting tasks, while its mechanical resilience ensures consistent performance across shift rotations and multi-year service intervals—minimizing recalibration frequency and total cost of ownership.

FAQ

Is the i-D33P suitable for washdown environments?
No. The indicator housing is rated IP20; only the load cell is IP65. It must be used exclusively in dry, non-corrosive industrial areas.
Can the scale be calibrated internally using a built-in routine?
It supports external calibration only—using certified test weights traceable to national standards. No internal calibration mechanism is present.
Does the device support NIST-traceable calibration certificates?
Yes—when purchased with OHAUS-certified calibration services, full documentation including uncertainty budgets and traceability statements per ISO/IEC 17025 is provided.
What is the maximum cable length supported for RS232 communication?
Up to 15 meters using shielded twisted-pair cabling meeting EIA/TIA-232-F specifications.
Is firmware upgrade capability available for end users?
Firmware updates require authorized OHAUS service personnel and proprietary diagnostic hardware; no field-upgradeable firmware is shipped with the unit.
