OHAUS Defender 3000 i-D33P30B1R5ZH Industrial Platform Scale

Overview

The OHAUS Defender 3000 i-D33P30B1R5ZH is a rugged, general-purpose industrial platform scale engineered for reliable performance in demanding production, packaging, warehousing, and logistics environments. Built upon OHAUS’ legacy of precision weighing instrumentation, this scale employs electromagnetic force compensation (EMFC) technology for stable, drift-resistant measurement across variable ambient conditions. Its core architecture integrates a high-stability aluminum load cell (IP65-rated), a corrosion-resistant 304 stainless steel weighing pan, and a reinforced carbon steel frame with powder-coated square-tube construction — delivering mechanical integrity under repeated loading cycles up to its rated capacity. Designed explicitly for dry industrial settings (non-hazardous, non-corrosive atmospheres), the scale meets fundamental metrological requirements for routine process weighing tasks where repeatability, ease of operation, and long-term mechanical resilience are prioritized over laboratory-grade resolution.

Key Features

• Large 6-digit, 7-segment multi-color backlit LCD display (45 mm character height) optimized for visibility in low-light or high-glare factory environments.
• Three-color checkweighing indication (red/yellow/green LED backlight) enabling immediate visual pass/fail assessment against user-defined target weights — eliminating need for operator interpretation of numeric deviations.
• Durable mechanical push-button interface with tactile feedback, designed for gloved-hand operation and resistant to dust ingress per IP65-rated load cell enclosure.
• Flexible power options: standard AC adapter (110–240 VAC, 50/60 Hz) and integrated rechargeable sealed lead-acid battery (providing ≥8 hours continuous operation on full charge).
• Modular mounting system featuring an aluminum U-shaped bracket and adjustable leveling feet, supporting benchtop, wall-mount, or pedestal installation configurations.
• Robust mechanical construction: 304 stainless steel pan; powder-coated carbon steel square-tube base; ABS engineering plastic housing with reinforced structural ribs.

Sample Compatibility & Compliance

The i-D33P30B1R5ZH supports discrete solid objects and packaged goods within its specified capacity range (model-dependent; consult technical datasheet for exact max load). It is not intended for liquid, viscous, or airborne particulate applications. The scale complies with international electromagnetic compatibility standards (IEC 61326-1:2013 for industrial environments) and meets basic safety requirements per IEC 61010-1:2010. While not certified for legal-for-trade use in all jurisdictions (e.g., NTEP, EC Type Approval), it is suitable for internal process control, inventory management, and non-regulated quality checks. Its design aligns with Good Manufacturing Practice (GMP) principles for equipment used in pharmaceutical and food manufacturing support operations — particularly where documented calibration, routine verification, and environmental robustness are required.

Software & Data Management

The scale provides native serial communication via standard RS232 interface (9600 baud, ASCII protocol), enabling direct integration with label printers, PLCs, or legacy MES systems. Optional USB (virtual COM port) and Ethernet (TCP/IP) modules expand connectivity for modern data acquisition workflows. No proprietary software is bundled; however, the device supports industry-standard protocols compatible with common SCADA platforms, Excel-based logging tools (via terminal emulation), and custom-developed applications. Audit-trail functionality is not embedded; users must implement external timestamped logging if required for GLP/GMP traceability. Calibration and configuration parameters are stored in non-volatile memory and retain settings after power cycling.

Applications

• Production line checkweighing of pre-packaged consumer goods (e.g., bottles, cartons, trays) to verify fill consistency prior to palletizing.
• Inventory reconciliation and cycle counting in warehouse distribution centers using piece-count mode with automatic average piece weight (APW) calculation.
• Dynamic accumulation of batch weights during material blending or kitting operations.
• Shipping and receiving verification for inbound/outbound freight documentation.
• Work-in-progress (WIP) tracking in automotive, electronics, and industrial component assembly lines.
• Raw material receipt inspection in food processing facilities where moisture-sensitive or ambient-dry storage conditions prevail.

FAQ

Is the i-D33P30B1R5ZH approved for trade use (e.g., NTEP or MID)?

No — this model is designated for industrial process control only and does not carry legal-for-trade certification in North America, the EU, or other regulated markets. For commercial transactions requiring statutory accuracy, consult OHAUS’ certified Defender 5000 or Adventurer series.
What is the ingress protection rating of the entire unit?

The load cell is IP65-rated; the indicator housing and base structure are not formally IP-rated but are engineered for dry industrial environments with resistance to dust accumulation and incidental splashes.
Can the scale be calibrated internally without external weights?

Yes — it supports internal calibration via built-in reference mass; however, periodic external verification using traceable test weights is recommended per ISO/IEC 17025 and internal quality procedures.
Does the battery support hot-swapping?

No — the sealed lead-acid battery requires power-down for replacement; runtime monitoring is displayed as a 4-level icon on the LCD.
Are firmware updates available, and how are they performed?

Firmware updates are released periodically by OHAUS and deployed via RS232 connection using OHAUS-provided utility software; no over-the-air or USB mass-storage update method is supported.
