Overview
The Defender® 6000 Washdown Scale (i-D61PW) is an industrial-grade, high-protection weighing platform engineered for rigorous hygienic environments. Built upon OHAUS’ legacy of precision metrology and process reliability, this scale operates on electromagnetic force compensation (EMFC) technology—ensuring stable, drift-free readings under dynamic operational conditions typical of wet processing zones. Its dual IP68 and IP69K ingress protection ratings certify full resistance to high-pressure, high-temperature washdown cycles, submersion up to 1.5 m for 30 minutes, and exposure to aggressive cleaning agents including caustic soda, chlorine-based sanitizers, and food-grade peracetic acid solutions. Designed specifically for compliance-driven sectors—including FDA-regulated food manufacturing, GMP-compliant pharmaceutical packaging, and ISO 22000-certified chemical blending—the i-D61PW meets NSF/ANSI Standard 18 for food equipment and supports HACCP prerequisite programs through traceable, auditable weighing workflows.
Key Features
- IP68/IP69K-rated construction: Fully sealed 316 stainless steel load cell with laser-welded housing; corrosion-resistant U-frame base and weighing pan; food-grade polycarbonate indicator housing compliant with EU Regulation (EC) No. 1935/2004
- Hygienic mechanical architecture: Smooth, crevice-free surfaces; no exposed fasteners or threaded inserts; sloped pan edges for rapid liquid runoff; removable rubber feet with adjustable leveling
- 6-digit, 7-segment white-backlit LCD display (45 mm character height); triple-color LED checkweighing bar (red/yellow/green) with configurable tolerance thresholds
- 150% overload protection; auto-zero tracking; automatic tare; programmable auto-off and low-battery warning; key lockout and menu lock functions
- Configurable environmental filtering (low/medium/high) to suppress vibration-induced noise in high-traffic production lines or near hydraulic presses and conveyors
- Real-time GLP/GMP clock with date/time stamping on printouts and data exports—enabling audit-ready documentation per FDA 21 CFR Part 11 requirements
Sample Compatibility & Compliance
The i-D61PW accommodates bulk solids, prepackaged goods, tote containers, and intermediate bulk containers (IBCs) across capacities up to 600 kg (1320 lb) with readability down to 200 g (0.2 kg). Its 316 stainless steel pan (standard on models ≤600 kg) resists pitting from saltwater exposure, organic acids, and enzymatic residues common in meat, dairy, and bakery processing. All wetted components comply with FDA 21 CFR §177.1520 (food-contact plastics) and EN 1935/2004 Annex I. The scale is certified by NSF International to NSF/ANSI 18 (Food Equipment), and its firmware architecture supports electronic signature capture and audit trail generation required under GxP environments. Optional magnetic infrared communication enables cable-free data transmission to PLCs or MES systems without breaching the IP69K seal.
Software & Data Management
The integrated firmware supports six embedded application modes: standard weighing, parts counting (with APW optimization for improved accuracy at low piece weights), percentage weighing, checkweighing, counting-by-weight, and dynamic weighing with hold function. Data output is available via RS-232 (standard), USB-C (optional), or infrared (magnetic adapter, optional). All weight records include timestamp, operator ID (if configured), net/gross/tare values, and pass/fail status for checkweighing events. Export formats include CSV and TXT for direct ingestion into LIMS, SAP QM, or TrackWise. Firmware versioning, calibration history, and user access logs are retained locally with tamper-evident timestamps—meeting ALCOA+ principles for data integrity in regulated industries.
Applications
- Food production: In-line checkweighing of filled trays, pouches, and cartons prior to metal detection and case packing
- Pharmaceutical secondary packaging: Verification of tablet blister counts, vial fill weights, and kit assembly completeness
- Chemical formulation: Accurate batching of raw materials under wet-process conditions where solvent vapors or particulate dust are present
- Logistics & distribution: Pallet and tote reconciliation during warehouse receiving, staging, and outbound loading
- Clean-in-place (CIP) validation: Monitoring detergent concentration and rinse water volume via gravimetric dosing control
FAQ
Is the i-D61PW suitable for use in sterile cleanrooms?
No—it is rated for wet industrial environments (e.g., washdown zones), not ISO Class 5–8 cleanrooms. For laminar flow or aseptic applications, consider OHAUS Adventurer® PRO with HEPA-filtered enclosures.
Does the scale support external calibration with NIST-traceable weights?
Yes—internal calibration is performed using factory-installed reference masses; external calibration is supported via two-point linear verification using certified test weights meeting ASTM E74 Class F or ISO 9001 calibration standards.
Can the checkweighing thresholds be modified remotely via network command?
Not natively—thresholds are configured locally via keypad or PC utility software (OHAUS SmartConnect™); however, Modbus RTU over RS-232 allows threshold parameter read/write via PLC integration.
What is the warranty coverage for the load cell under continuous washdown conditions?
OHAUS provides a 5-year limited warranty on the welded 316 stainless steel load cell when used within specified environmental limits (ambient temperature: −10 °C to +40 °C; humidity: ≤90% RH non-condensing).
