Overview
The SARTORIUS Midrics Series Industrial Floor Scale is a modular, legally compliant weighing platform engineered for high-reliability operation in demanding production, logistics, and process environments. Built on OIML R76 and NTEP Class III/IIIL metrological frameworks, the Midrics platform supports both verified trade-use applications and non-legal industrial monitoring tasks. Its core architecture employs electromagnetic force compensation (EMFC) or strain-gauge load cell technology—depending on model configuration—to deliver stable, temperature-compensated measurements across wide ambient ranges (–10 °C to +40 °C). Unlike fixed-design floor scales, Midrics adopts a component-based system: users select from pre-validated base frames, load cell modules, indicator units, platform decks, and optional hazardous-area certifications—enabling precise adaptation to site-specific mechanical, regulatory, and environmental constraints.
Key Features
- Modular scalability: Configure complete systems, individual components (e.g., load cells, indicators, platforms), or retrofit existing infrastructure without full replacement.
- Environmental resilience: Painted variants meet IP65 for dust-tightness and low-pressure water jet resistance; stainless steel (1.4301/AISI 304) versions achieve IP67 (temporary immersion) and IP68 (continuous submersion under defined conditions), validated per IEC 60529.
- Legal metrology compliance: Supports three-tier resolution modes—1×3000e and 2×3000e for official trade use (e.g., shipping, batching, tolling), and 15,000d for internal process control—each traceable to national standards via SARTORIUS factory calibration certificates.
- Dual-indicator capability: Two independent display units can be mounted at operator-defined heights and orientations, supporting simultaneous local readout and remote PLC/HMI integration via RS-232, RS-485, or Ethernet/IP.
- Mechanical stability: Four heavy-duty adjustable leveling feet with integrated bubble-level indicators (LCE/NCE models) ensure rapid, repeatable installation on uneven concrete or grated flooring common in warehouses and manufacturing bays.
- Hazardous area readiness: Optional ATEX 2014/34/EU and IECEx certification enables safe deployment in Zone 2 (gas) and Zone 22 (combustible dust) per EN 60079-0, -10, -11, and -31 standards.
Sample Compatibility & Compliance
Midrics scales accommodate diverse load geometries—from palletized goods and IBCs to bulk containers and assembly jigs—across 13 standardized platform dimensions (ranging from 300 × 400 mm to 1,500 × 2,000 mm). All configurations comply with ISO 9001 quality management requirements and are designed for GLP/GMP-aligned environments where audit-ready documentation is mandatory. Factory calibration reports include uncertainty budgets per ISO/IEC 17025:2017, and optional verification services align with EU Directive 2014/31/EU for non-automatic weighing instruments. Traceability extends to national metrology institutes (PTB, NIST, NPL) via SARTORIUS’ accredited calibration laboratory network.
Software & Data Management
The Midrics ecosystem integrates natively with SARTORIUS LabX® Industrial Edition and third-party MES/SCADA platforms via OPC UA and Modbus TCP protocols. Indicator firmware supports configurable data logging (time-stamped weight, tare, net/gross mode, operator ID), automatic zero-tracking, and batch-triggered output signals. Audit trails—including parameter changes, calibration events, and user logins—are retained locally and exportable in CSV or XML formats. For regulated industries, optional 21 CFR Part 11-compliant user access controls, electronic signatures, and immutable event logs are available through LabX validation packages.
Applications
Midrics scales serve as primary or secondary weighing nodes in pharmaceutical ingredient dispensing, food processing line checkweighing, automotive component kitting, chemical drum filling, recycling facility material sorting, and warehouse receiving/inventory reconciliation. Their modularity supports dynamic reconfiguration—for example, upgrading a 300 kg capacity unit to 1,000 kg by replacing only the load cell module and recalibrating—minimizing downtime and lifecycle cost. In continuous-process settings, analog 4–20 mA outputs feed real-time mass flow calculations into DCS systems, while digital interfaces support automated label printing and ERP transaction posting.
FAQ
Is the Midrics scale suitable for use in wet cleaning environments such as food processing plants?
Yes—stainless steel (1.4301/AISI 304) models with IP68 rating withstand repeated high-pressure washdown cycles using caustic or acidic sanitizers, provided seals remain undamaged and maintenance intervals follow SARTORIUS Technical Bulletin TB-MID-07.
Can I integrate Midrics with my existing PLC system without custom programming?
All Midrics indicators support native Modbus RTU/TCP and EtherNet/IP drivers; configuration files and sample ladder logic are available in the SARTORIUS Industrial Integration Library.
Does SARTORIUS provide on-site verification for legal-for-trade use?
Yes—certified service engineers perform on-site initial verification and periodic re-verification per local metrological authority requirements (e.g., UK Trading Standards, German Eichamt, US State Weights & Measures).
What is the warranty coverage for explosion-proof configurations?
ATEX/IECEx-certified units carry a 36-month limited warranty covering materials and workmanship, excluding consumables and damage from improper installation or unauthorized modification.
How often does the scale require recalibration in a stable indoor environment?
Under stable temperature/humidity conditions and routine daily verification with certified test weights, annual recalibration is recommended; however, risk-based assessment per ISO/IEC 17025 may extend intervals with documented justification.
