Unicise YANXIANG Series 10 mg Electromagnetic Force Weighing Module

Overview

The Unicise YANXIANG Series 10 mg Electromagnetic Force Weighing Module is an industrial-grade, high-stability load cell solution engineered for precision integration into automated manufacturing, continuous batching, and inline quality control systems. Based on electromagnetic force compensation (EMFC) transduction—where gravitational force on the load is precisely balanced by a controlled electromagnetic field—the module delivers metrologically traceable mass measurement with 10 mg readability across five capacity variants (2.2 kg to 8.2 kg). Unlike strain-gauge-based modules, EMFC architecture eliminates mechanical hysteresis and creep effects, ensuring long-term linearity and repeatability under dynamic loading conditions. Designed for embedded deployment in OEM equipment, the module operates within a tightly controlled environmental envelope (+10 °C to +30 °C), making it suitable for climate-stabilized production floors, pharmaceutical formulation lines, and fine chemical dosing stations where thermal drift must be minimized.

Key Features

• Uni-block EMFC Sensor Core: Proprietary monolithic electromagnetic force transducer with integrated feedback coil and position-sensing photodiode, delivering <0.005% linearity error and <0.002% repeatability (per ISO 7500-1 Class III verification methodology).
• Compact Integrated Architecture: Fully self-contained electronics—including excitation driver, analog-to-digital conversion (24-bit sigma-delta ADC), and real-time digital filtering—are housed within a single stainless-steel enclosure (IP65-rated), eliminating external junction boxes or signal conditioners.
• Robust Mechanical Design: 316L stainless-steel housing with integrated overload protection (mechanical stop + electronic saturation limiter), rated for ≥500% overcapacity without permanent deformation or calibration shift.
• Dual-Mode Mounting: Supports both top-loading (standard 60 mm stainless-steel pan) and bottom-loading configurations via reversible mounting interface, enabling seamless integration into conveyor-fed dispensers, hopper-mounted feeders, or gravimetric loss-in-weight (LIW) systems.
• Multi-Protocol Digital Interface: Simultaneous DB9 (RS-232/SBI-compliant), Type-C (USB CDC virtual COM port), and USB-A (for optional display unit) connectivity; firmware supports configurable baud rates (1200–115200 bps), packet framing, and auto-handshaking for deterministic data exchange.
• On-Site Calibration Flexibility: External calibration routine accepts user-defined reference masses (minimum 1/3 full scale); calibration coefficients are stored in non-volatile EEPROM with write-protection logic to prevent accidental overwrite during power cycling.

Sample Compatibility & Compliance

The YANXIANG module is compatible with solid particulates, granules, powders, and small packaged components typical in food ingredient blending, catalyst dosing, tablet coating, and additive manufacturing feedstock handling. Its sealed construction prevents ingress of dust or light splashes, satisfying IP65 requirements for non-hazardous industrial environments. While not certified to OIML R76 or NTEP for legal-for-trade applications, the module conforms to key elements of ISO 9001:2015 process control instrumentation requirements and supports GLP/GMP-aligned audit trails when paired with compliant host software (e.g., timestamped calibration logs, operator ID tagging via external authentication). It meets CE marking requirements per EMC Directive 2014/30/EU and Low Voltage Directive 2014/35/EU.

Software & Data Management

Firmware supports ASCII-based command-response protocol (SBI v2.1 and SICS v1.3), enabling direct integration with PLCs (Siemens S7, Rockwell ControlLogix), SCADA platforms (Ignition, WinCC), and custom LabVIEW or Python-based control suites. All communication includes CRC-16 error checking and timeout recovery. Optional Unicise ConfigTool (Windows/Linux) provides GUI-based parameter configuration—including filter bandwidth adjustment (1–10 Hz), zero-tracking enable/disable, and tare memory management. Data output formats include raw mass (g), net mass (g), and status flags (stable, overload, underload, calibration required). When used with FDA 21 CFR Part 11-compliant host systems, the module’s deterministic response time (<100 ms settling at 99.9% of final value) and immutable calibration history support electronic record integrity.

Applications

• Gravimetric loss-in-weight (LIW) feeders for polymer extrusion and compounding lines
• In-line checkweighing stations for blister-packaged diagnostics or oral solid dosage forms
• Automated powder dispensing in battery cathode slurry preparation
• Dynamic batching control in high-value flavor/fragrance compound synthesis
• Material consumption monitoring in metal additive manufacturing powder recycling loops
• OEM integration into robotic sample prep workstations for analytical chemistry labs

FAQ

Is this module suitable for use in hazardous areas?
No. The YANXIANG series is rated for non-classified industrial environments only (IP65, CE-compliant). It does not carry ATEX, IECEx, or UL HazLoc certification.
Can the module operate continuously at its maximum rated capacity?
Yes—continuous operation at full scale is permitted provided ambient temperature remains within +10 °C to +30 °C and mechanical shock/vibration levels stay below 5 g RMS (per IEC 60068-2-6).
What is the recommended calibration frequency for GMP-regulated processes?
Per USP <797> and EU Annex 1 guidance, initial calibration upon installation, followed by daily performance verification using a traceable check weight, and full recalibration every 6 months—or after any physical impact, relocation, or environmental excursion beyond specification limits.
Does the module support analog output (e.g., 4–20 mA or 0–10 V)?
No. The YANXIANG series is digitally native; analog output requires an external signal converter compatible with its RS-232 or USB interface.
Is firmware update capability available in the field?
Yes—firmware upgrades are performed via USB-A connection using Unicise ConfigTool; updates preserve all user-configured parameters and calibration coefficients.
