Overview
The OHAUS Defender 3000 i-D33P30B1R1ZH is an industrial-grade platform scale engineered for high-reliability weighing in demanding production, packaging, warehousing, and logistics environments. Built upon OHAUS’ proven Defender 3000 platform architecture, this model employs electromagnetic force restoration (EMFR) sensing technology—optimized for robustness and long-term stability under repeated mechanical loading. Its design prioritizes operational continuity in dry industrial settings, with a sealed IP65-rated aluminum load cell, corrosion-resistant 304 stainless steel weighing pan, and powder-coated carbon steel frame constructed from structural square tubing. The scale supports four primary operational modes—weighing, counting, checkweighing, and accumulation—enabling seamless integration into quality control checkpoints, assembly line verification stations, and inventory management workflows.
Key Features
- Large-format, 6-digit, 7-segment LCD display with multi-color backlight (red/yellow/green), featuring 45 mm character height for high-visibility readouts under ambient lighting conditions up to 50,000 lux.
- Three-color visual checkweighing feedback: green indicates target weight achieved, yellow signals tolerance band warning, and red triggers out-of-specification alert—eliminating operator interpretation delay.
- Dual-power operation: integrated rechargeable lead-acid battery (up to 80 hours runtime on full charge) and universal AC adapter (110–240 VAC, 50/60 Hz) for uninterrupted deployment across global facilities.
- Rugged mechanical construction: 304 stainless steel pan (standard), square-tube carbon steel base with epoxy-polyester coating, ABS engineering plastic indicator housing with reinforced metal U-bracket for wall, pole, or bench mounting.
- Tactile membrane keypad with ergonomic layout—designed for gloved-hand operation and resistant to dust ingress per IP65 environmental rating.
Sample Compatibility & Compliance
The i-D33P30B1R1ZH accommodates standard industrial packages, palletized goods, and bulk containers within its rated capacity (model-specific; consult datasheet for exact max load). It complies with international metrological requirements for non-automatic weighing instruments per OIML R76-1 (2021 edition) and meets EU Directive 2014/32/EU (Measuring Instruments Directive, MID) for Class III accuracy class applications. The device supports GLP/GMP-aligned audit trails when connected to compliant data management systems. While not certified for hazardous locations, its IP65-rated load cell and sealed indicator housing ensure reliable performance in dry, non-corrosive industrial atmospheres per IEC 60529 standards.
Software & Data Management
The scale features native RS232 serial interface as standard for direct connection to label printers, PLCs, or legacy industrial PCs. Optional USB (virtual COM port) and Ethernet (TCP/IP) modules enable modern networked data capture—supporting CSV export, real-time weight streaming, and integration with MES/ERP platforms via Modbus TCP or ASCII protocols. Firmware supports user-configurable data formatting, auto-print triggers, and timestamped weight logs. When interfaced with OHAUS’s optional ScaleConnect software (v3.0+), the system provides configurable audit trail generation, user access levels, and electronic signature support—facilitating alignment with FDA 21 CFR Part 11 requirements for regulated environments.
Applications
- Production line checkweighing of packaged consumer goods (e.g., food, pharmaceuticals, cosmetics) against defined upper/lower limits.
- Inventory reconciliation via piece counting mode—calibrated using sample weights to achieve ±0.2% counting accuracy at typical unit masses ≥5 g.
- Accumulation of batch weights during filling or blending operations—retaining running totals with tare memory and auto-reset functions.
- Shipping and receiving verification: gross/net/tare weight capture with automatic label print initiation upon stable reading confirmation.
- Work-in-process (WIP) material tracking in discrete manufacturing cells where ruggedness and fast stabilization (<1.5 s) are critical.
FAQ
What is the maximum capacity and readability of the i-D33P30B1R1ZH model?
Capacity and readability vary by specific configuration; refer to the official OHAUS technical datasheet for your regional variant (e.g., 30 kg × 1 g, 60 kg × 2 g).
Is the scale suitable for wet or washdown environments?
No—while the load cell is IP65-rated, the indicator housing and keypad are rated IP65 only under dry conditions. It is not designed for direct hose-down or chemical exposure.
Can the scale be calibrated internally or does it require external weights?
It supports internal calibration via built-in reference mass; external calibration with traceable weights is recommended annually or after mechanical shock per ISO/IEC 17025 guidelines.
Does the USB or Ethernet option support bi-directional communication?
Yes—both optional interfaces support full duplex ASCII command/response protocol and Modbus TCP slave functionality for host-initiated control and real-time data polling.
Is firmware update capability available through the front panel?
Firmware updates require connection to a PC via RS232 or USB and use of OHAUS-provided utility software; no over-the-air or panel-based update function is implemented.
