Overview
The Defender® 6000 Washdown Scale (Model i-D61PW) is a high-integrity industrial floor scale engineered for rigorous hygienic environments where moisture resistance, chemical exposure, and frequent high-pressure cleaning are routine operational requirements. Built to meet the dual ingress protection standards of IP68 and IP69K, this scale employs a fully sealed mechanical architecture—featuring welded 316 stainless steel load cells, corrosion-resistant structural components, and NSF-certified food-grade polycarbonate indicator housing. Its measurement principle relies on precision strain-gauge transduction within hermetically sealed sensors, delivering stable, repeatable mass readings under dynamic washdown conditions. Designed explicitly for compliance-driven sectors—including food processing, pharmaceutical manufacturing, and fine chemical production—the i-D61PW supports Hazard Analysis and Critical Control Point (HACCP) protocols and aligns with Good Manufacturing Practice (GMP) and Good Laboratory Practice (GLP) documentation workflows.
Key Features
- IP68 & IP69K-rated enclosure: Fully submersible (up to 1 m for 30 min) and resistant to high-temperature, high-pressure jet cleaning (up to 100 bar, 80 °C).
- NSF/ANSI Standard 173 certified: Validated for use in food contact zones and compliant with FDA 21 CFR Part 11 data integrity prerequisites when paired with audit-trail-enabled software.
- 316 stainless steel construction: Load-receiving surfaces—including pan, frame, column (excluding 300 kg and 600 kg variants), and U-shaped support structure—resist pitting, chloride-induced stress corrosion, and organic acid degradation.
- 6-digit, 45 mm high-contrast white-backlit LCD display with intuitive icon-based navigation and real-time status indicators (e.g., stability, overload/underload, battery level).
- Triple-color LED checkweighing bar (red/yellow/green) with programmable tolerance thresholds and visual feedback synchronized to weight stabilization.
- 150% overcapacity protection; auto-zero tracking; auto-tare; adjustable environmental filtering (for vibration or air current compensation); programmable auto-off delay.
- Integrated GLP/GMP-compliant real-time clock with date/time stamping on printed or exported records.
Sample Compatibility & Compliance
The i-D61PW accommodates bulk solids, packaged goods, tote containers, and intermediate bulk containers (IBCs) across primary and secondary manufacturing stages. Its 316 stainless steel pan and sealed sensor assembly eliminate crevices that harbor microbial growth or residue accumulation—critical for USDA-FSIS and EU Regulation (EC) No. 852/2004 adherence. The scale meets NSF/ANSI 173 Section 6.2 (Materials Safety), ISO 22000:2018 Clause 8.5.2 (Monitoring Equipment Calibration), and supports validation per ASTM E899-21 (Standard Guide for Validation of Weighing Systems). Optional magnetic infrared communication enables wireless data transfer without compromising IP integrity—ideal for cleanroom-adjacent staging areas.
Software & Data Management
When connected via optional IR interface or RS-232/USB, the i-D61PW exports weight data with embedded timestamps, operator ID (via keypad entry), and process metadata (e.g., batch ID, recipe code) to LIMS, MES, or ERP systems. All stored records include digital signatures and immutable audit trails meeting FDA 21 CFR Part 11 Subpart B §11.10(a) requirements. Internal memory retains up to 1,000 weight events with time/date stamps, and firmware supports secure configuration locking to prevent unauthorized parameter changes during production shifts.
Applications
- Food & Beverage: In-line checkweighing of filled pouches, trays, and cartons; raw material receipt verification; yield reconciliation at mixing/blending stations.
- Pharmaceuticals: Batch component dispensing under cGMP Annex 11; active pharmaceutical ingredient (API) inventory reconciliation; container tare-and-fill operations.
- Chemicals: Hazardous material drum weighing with spill containment integration; catalyst dosage control in reactor feed lines.
- Logistics & Distribution: Palletized load verification prior to cold-chain dispatch; warehouse cycle-counting with barcode-triggered weight capture.
FAQ
What does IP69K certification mean for daily operation?
IP69K certifies resistance to high-pressure, high-temperature water jets (80 °C, 100 bar, 15 cm distance, 30° spray angle)—enabling full-surface sanitization without disassembly.
Is calibration traceability supported?
Yes—internal calibration routines accept external weights traceable to NIST or national metrology institutes; calibration logs include operator ID, date/time, and deviation values.
Can the scale interface with PLC-based control systems?
Via optional RS-232 or 4–20 mA analog output, the i-D61PW provides real-time weight signals compatible with Siemens S7, Allen-Bradley ControlLogix, and Beckhoff TwinCAT platforms.
Does the indicator support multi-language UI?
The firmware includes English, Spanish, French, German, and Simplified Chinese language options—configurable via front-panel menu or PC utility.
How is firmware updated in validated environments?
Updates are performed via encrypted USB drive with version-controlled release packages; each update generates a system log entry compliant with 21 CFR Part 11 electronic record retention rules.
