METTLER TOLEDO SCS/ZCS/ZCU/SCU Series Truck Scales

Overview

The METTLER TOLEDO SCS, ZCS, ZCU, and SCU series truck scales represent a modular family of high-accuracy, heavy-duty weighing systems engineered for permanent or semi-permanent installation in demanding industrial environments—including ports, bulk terminals, manufacturing plants, quarries, and logistics hubs. These systems operate on the principle of load cell-based force measurement, where calibrated strain-gauge or electromagnetic force-compensation transducers convert mechanical load into proportional electrical signals. Each scale platform is structurally designed to comply with OIML R76-1 requirements for non-automatic weighing instruments (NAWI), supporting legal-for-trade applications under national metrological regulations. The series integrates seamlessly with METTLER TOLEDO’s IND570 or POWERCELL® digital indicator platforms, enabling real-time weight capture, dynamic axle weighing, and gross/net/tare computation—critical for freight compliance, inventory reconciliation, and production material tracking.

Key Features

• Modular steel or concrete deck configurations: SCS (steel deck, shallow pit), ZCS (steel deck, flush mount), ZCU (concrete deck, shallow pit), SCU (concrete deck, full pit)—each optimized for site-specific foundation requirements and traffic loading profiles.
• POWERCELL® PDX® or STRAIN GAUGE load cells with hermetically sealed stainless-steel housings, rated IP68/IP69K, offering long-term stability (<0.01 %FS/year drift) and resistance to moisture, corrosion, and mechanical shock.
• ATEX Zone 1/2 and IECEx Ex d/ia certified variants available for hazardous areas—featuring intrinsic safety barriers, galvanic isolation, flameproof enclosures, and optical fiber data transmission to eliminate ignition risks from sparks, surface temperatures, or electrostatic discharge.
• Integrated diagnostics: Real-time load cell health monitoring, cable integrity checks, temperature compensation, and automatic zero-tracking—reducing unplanned downtime and simplifying preventive maintenance.
• Robust mechanical architecture: Reinforced side guides, anti-lift devices, and adjustable mounting feet ensure alignment stability under thermal expansion, ground settlement, or heavy off-center loading conditions.

Sample Compatibility & Compliance

These truck scales are compatible with all standard commercial vehicle classes—from rigid trucks and articulated lorries to railcars and container chassis—supporting both static and slow-motion (≤10 km/h) weighing modes. All models meet OIML R76-1 Class C3 or C4 accuracy specifications, with verification scale intervals (e) ranging from 2 kg to 50 kg depending on capacity. For regulated industries, optional configurations comply with ISO/IEC 17025 calibration traceability, ASTM E74 load cell verification protocols, and EU Directive 2014/31/EU (Measuring Instruments Directive). Hazardous-area variants carry full ATEX 2014/34/EU and IECEx certification documentation, including detailed zone classification guidance per EN 60079-10-1 (gas) and EN 60079-10-2 (dust).

Software & Data Management

The scales interface natively with METTLER TOLEDO’s iQ-Scale™ software suite—a browser-based platform supporting multi-site fleet management, customizable weighing workflows, audit trail generation, and electronic signature capture. Data export adheres to ISO 8601 timestamps and CSV/JSON formats for ERP integration (SAP, Oracle, Microsoft Dynamics). Optional 21 CFR Part 11 compliance packages include role-based access control, electronic record retention (≥3 years), and immutable audit logs—enabling GLP/GMP-aligned operations in pharmaceutical raw material intake or food-grade ingredient receipt.

Applications

• Port authority gatehouse operations: Automated vehicle identification (RFID/ANPR), weight verification against shipping manifests, and customs duty calculation.
• Mining and aggregate processing: Inbound ore tonnage validation, outbound product dispatch control, and conveyor belt feed rate correlation.
• Recycling facilities: Material composition tracking by weight class (ferrous/non-ferrous/scrap), yield optimization, and landfill diversion reporting.
• Hazardous goods terminals: Safe weighing of tankers carrying flammable liquids or compressed gases within classified zones—fully compliant with NFPA 497 and IEC 60079 standards.
• Manufacturing supply chain: JIT inbound logistics monitoring, supplier performance scoring via weight variance analytics, and MES-level material consumption reconciliation.

FAQ

What explosion protection certifications are available for the SCS/ZCS/ZCU/SCU series?
ATEX II 2G Ex db IIB T4 Gb, ATEX II 2D Ex tb IIIC T135°C Db, and IECEx Ex db IIB T4 Gb / Ex tb IIIC T135°C Db configurations are offered—subject to specific model variant and indicator pairing.
Can these truck scales be retrofitted with remote diagnostics or predictive maintenance tools?
Yes—via optional METTLER TOLEDO Remote Service Gateway (RSG) and cloud-connected iQ-Scale™ analytics, enabling real-time health dashboards, anomaly detection, and service ticket automation.
Is calibration traceability provided with each installation?
All installations include a factory calibration certificate traceable to NIST or PTB standards; on-site verification and periodic recalibration services follow ISO/IEC 17025-accredited procedures.
How does the system handle environmental challenges such as frost heave or heavy rainfall?
Concrete-deck models (ZCU/SCU) utilize deep-pit foundations with drainage channels and thermal break layers; steel-deck variants incorporate elevated mounting and IP68-rated junction boxes with condensate vents.
What level of integration is supported with third-party ERP or WMS platforms?
Standard RESTful API, OPC UA, and Modbus TCP protocols are supported; pre-built connectors exist for SAP WM/EWM, Manhattan SCALE, and HighJump WMS.
