OHAUS Defender 3000 i-D33P300B1X5ZH Industrial Floor Scale

Overview

The OHAUS Defender 3000 i-D33P300B1X5ZH is an industrial floor scale engineered for high-reliability weighing in production, packaging, warehousing, and logistics environments. Designed around a robust mechanical architecture and precision analog-to-digital conversion, it employs a calibrated aluminum load cell with IP65 ingress protection to ensure stable signal integrity under variable ambient conditions—including dust exposure and incidental moisture. Its square-tube carbon steel frame, powder-coated for corrosion resistance, supports a 304 stainless steel weighing pan rated for continuous operation at 300 kg capacity with 100 g readability. The system operates on dual power sources—universal-input AC supply (110–240 VAC) and an integrated sealed lead-acid battery—enabling uninterrupted use during power fluctuations or mobile deployment across factory floors. As part of the Defender 3000 platform, this model adheres to OHAUS’s global quality control protocols aligned with ISO 9001-certified manufacturing practices in Shanghai.

Key Features

• Multi-color backlit LCD display with 45 mm digit height ensures legibility in low-light or high-glare industrial settings; tri-color checkweighing feedback (red/yellow/green) enables immediate visual pass/fail assessment without operator interpretation.
• Modular indicator housing constructed from impact-resistant ABS engineering plastic, reinforced with a metal U-bracket for wall, pedestal, or bench mounting flexibility.
• Sealed tactile keypad designed for repeated actuation in gloves or dusty conditions; no exposed mechanical switches to minimize maintenance.
• Four primary operational modes: standard weighing, parts counting (with automatic average piece weight calculation), dynamic checkweighing with configurable upper/middle/lower limits, and batch accumulation with totalization memory.
• Standard RS232 serial interface supports direct connection to label printers, PLCs, or legacy MES systems; optional USB host/device or Ethernet (TCP/IP) modules enable integration into modern IIoT-enabled infrastructure.

Sample Compatibility & Compliance

The i-D33P300B1X5ZH is optimized for static and quasi-static weighing of packaged goods, raw materials, palletized loads, and intermediate assemblies. Its 304 stainless steel pan and sealed sensor assembly meet IP65 requirements for resistance to dust ingress and low-pressure water jets—making it suitable for dry industrial zones classified under IEC 60529. While not certified for hazardous locations (ATEX/IECEx), its construction complies with RoHS Directive 2011/65/EU and carries CE marking per EU Machinery Directive 2006/42/EC and Electromagnetic Compatibility Directive 2014/30/EU. OHAUS maintains full traceability documentation for calibration certificates, material certifications (e.g., EN 10088-1 for 304 SS), and factory test reports—supporting internal quality audits and GLP-aligned recordkeeping.

Software & Data Management

The scale operates independently without external software but supports ASCII-based data streaming via RS232 for seamless ingestion into third-party applications—including ERP (SAP, Oracle), WMS (Manhattan SCALE, HighJump), and custom LabVIEW or Python-based acquisition tools. Optional Ethernet connectivity allows configuration through a web-based UI (HTTP/HTTPS) for IP address assignment, baud rate, and protocol framing parameters. All communication follows standard OHAUS ASCII command syntax (e.g., “P” for print, “S” for stable weight query). Audit trails are maintained locally for up to 1,000 weight events, including timestamp, mode, net/gross/tare values, and user-defined ID tags—sufficient for basic 21 CFR Part 11 compliance when paired with validated host software.

Applications

• Production line checkweighing of consumer goods (e.g., bottled beverages, boxed pharmaceuticals, automotive components) against defined tolerance bands.
• Inventory reconciliation via parts counting mode—particularly effective for uniform small parts such as fasteners, PCBs, or syringes.
• Shipping and receiving verification: gross weight capture prior to palletizing; tare subtraction for reusable containers.
• Batch accumulation in formulation or blending operations where cumulative mass tracking improves process repeatability.
• Quality assurance workflows requiring documented weight records for internal CAPA or supplier scorecard reporting.

FAQ

Is the i-D33P300B1X5ZH suitable for wet or washdown environments?

No—it is rated IP65 only at the load cell level; the indicator unit is IP54-rated and must be installed in dry, non-condensing indoor areas.
Can the scale be calibrated internally without external weights?

Yes, it supports internal span calibration using built-in reference circuitry, though external verification with NIST-traceable weights is required for ISO/IEC 17025-compliant processes.
Does the USB option support HID keyboard emulation?

No—the optional USB interface operates in CDC (virtual COM port) mode only; HID emulation is not implemented.
What is the battery life under typical usage?

With default backlight timeout (30 s) and moderate weighing frequency (~50 operations/hour), the included SLA battery provides ≥12 hours of continuous operation.
Is firmware upgrade supported in-field?

Yes—firmware updates can be performed via RS232 using OHAUS-provided utility software; Ethernet models support HTTP-based OTA updates.
