HARDY 1756-WS Weigh Scale Module – Precision Weighing Interface for ControlLogix Series
Imagine a high-throughput batching line suddenly producing out-of-spec product weights — with no reliable feedback loop, every kilogram of raw material becomes a liability. Without a dedicated, high-accuracy weigh scale interface integrated directly into your control architecture, operators are left guessing, quality teams are scrambling, and production losses compound by the hour. The HARDY 1756-WS Weigh Scale Module eliminates that risk by delivering real-time, certified-accuracy weight data directly into your Rockwell Automation ControlLogix backplane.
The 1756-WS occupies a unique position within the HARDY Process Solutions portfolio as a native ControlLogix rack-mount weighing module — one of the few solutions on the market that combines HARDY’s decades of load cell expertise with seamless Logix tag-based integration. Widely deployed across food & beverage, chemical processing, and bulk material handling facilities worldwide, it has become a benchmark for precision weighing in safety-critical and regulated environments.

Key Features & Benefits
- Native Logix Integration: Appears as a standard I/O module in Studio 5000 — no custom EDS files or third-party gateways needed, reducing commissioning time significantly.
- WAVERSAVER® Vibration Rejection: HARDY’s proprietary algorithm filters mechanical vibration from conveyor belts, mixers, and nearby machinery, ensuring stable weight readings in harsh plant environments.
- C2® Electronic Calibration: Calibrate the system without physical test weights using HARDY’s C2 certified load cells — critical for large-scale hoppers and tanks where physical calibration is impractical.
- Integrated Diagnostics: Real-time load cell health monitoring detects wiring faults, overloads, and drift before they cause downtime.
- Dual-Channel Capability: Supports multiple independent weigh scales within a single module slot, maximizing backplane density.
- Regulatory Compliance Ready: Designed to support NTEP and OIML certification requirements for legal-for-trade weighing applications.
Industry & Equipment Applications
- Food & Beverage: Batch ingredient dosing, checkweighing, and filling line control where recipe accuracy is mandatory.
- Chemical & Pharmaceutical: Reactor charge weighing, loss-in-weight feeders, and blending systems requiring 21 CFR Part 11 audit trails.
- Bulk Material Handling: Silo inventory management, truck/rail scale interfaces, and belt weigher integration.
- Plastics & Rubber: Gravimetric blending and extruder throughput control.
- Mining & Aggregates: Crusher feed control and stockpile measurement in high-vibration environments.
- Water & Wastewater: Chemical dosing systems requiring precise mass-flow control.
