Overview
The Defender® 6000 Washdown Scale (i-D61PW) is an industrial-grade, high-integrity weighing platform engineered for continuous operation in hygienic and demanding process environments. Built upon OHAUS’ legacy of precision metrology and robust mechanical architecture, this scale employs electromagnetic force compensation (EMFC) load cell technology — delivering stable, drift-resistant measurement performance under variable thermal and mechanical stress. Its dual IP68/IP69K ingress protection rating certifies full resistance to high-pressure, high-temperature washdown cycles (up to 80 °C, 100 bar), making it compliant with stringent sanitation protocols required in food manufacturing, pharmaceutical production, and fine chemical processing. The scale is NSF/ANSI Standard 173 certified for food equipment, supporting HACCP-aligned workflow validation and facilitating audit readiness under FDA 21 CFR Part 11 and EU GMP Annex 11 frameworks.
Key Features
- IP68/IP69K-rated sealed construction: Fully welded 316 stainless steel load cells, hermetically sealed electronics housing, and food-grade polycarbonate indicator enclosure resistant to caustic cleaners and steam sterilization
- Hygienic mechanical design: U-shaped 316 stainless steel support frame, seamless 316 stainless steel weighing pan and column (excluding 300 kg and 600 kg variants), zero crevice geometry for CIP/SIP compatibility
- 6-digit, 45 mm high-contrast white-backlit LCD display with intuitive icon-based navigation and real-time status indicators
- Triple-color LED checkweighing bar (red/yellow/green) with programmable tolerance bands and audible feedback options
- 150% overload protection with automatic over/underload detection, low-battery warning, auto-zero tracking, auto-tare, and user-configurable auto-off delay
- Configurable environmental filtering (low/high sensitivity modes) to suppress vibration-induced noise in dynamic floor-mounted installations
- Front-panel key lock function and password-protected parameter configuration to prevent unauthorized calibration or setup changes
Sample Compatibility & Compliance
The i-D61PW supports batch weighing, piece counting (APW-optimized algorithm), percentage weighing, checkweighing, dynamic weighing, and hold mode operations — all validated per OIML R76-1 and NTEP Class III accuracy requirements. Its structural materials meet FDA 21 CFR §177.1580 (food-contact polycarbonate) and ASTM A240/A240M (316 stainless steel). Full NSF/ANSI 173 certification confirms suitability for direct contact with raw and processed foodstuffs. The scale complies with ISO/IEC 17025 traceability requirements when used with accredited calibration services, and its internal GLP/GMP-compliant real-time clock enables time-stamped data logging for regulatory documentation.
Software & Data Management
The integrated indicator supports RS-232 and optional magnetic infrared (IR) wireless communication for seamless integration into MES, ERP, or LIMS platforms. All weight data exports include timestamp, operator ID (via optional keypad login), unit code, and gross/net/tare values. Audit trail functionality records configuration changes, calibration events, and firmware updates — satisfying 21 CFR Part 11 electronic record and signature requirements when deployed with validated system controls. Optional PC software (OHAUS Logger Pro) enables automated report generation, statistical process control (SPC) charting, and CSV/Excel export with customizable metadata fields.
Applications
This scale is routinely deployed in: ingredient batching stations within USDA-inspected meat processing facilities; tablet/capsule checkweighing lines under cGMP pharmaceutical manufacturing; bulk chemical dispensing in ISO 8 cleanrooms; frozen seafood portioning on wet processing floors; and warehouse receiving docks handling palletized goods in high-humidity coastal climates. Its rapid stabilization time (<1.5 s at full capacity) and immunity to condensation-induced drift ensure repeatable results across shift rotations and seasonal ambient fluctuations.
FAQ
What certifications does the i-D61PW hold for food industry use?
NSF/ANSI Standard 173, IP68/IP69K per IEC 60529, and compliance with FDA 21 CFR Part 11 for electronic records.
Is the load cell replaceable without recalibration?
No — the welded IP69K sensor is permanently sealed into the frame; replacement requires factory recalibration and re-certification.
Can the scale interface with a label printer for automated packaging?
Yes, via RS-232 serial output with configurable print triggers and ZPL/EPL-compatible command sets.
Does the indicator support multi-language UI?
Yes — English, Spanish, French, German, Chinese, and Japanese are preloaded; language selection is accessible through the setup menu.
What is the recommended calibration frequency under GMP conditions?
Daily operational verification using certified test weights, plus full external calibration every 3–6 months by an ISO/IEC 17025-accredited service provider.
