Unicise YANXIANG Series 100 mg Electromagnetic Force Weighing Module

Overview

The Unicise YANXIANG Series 100 mg Electromagnetic Force Weighing Module is an industrial-grade force restoration transducer engineered for high-precision, real-time mass measurement in automated process environments. Based on electromagnetic force compensation (EMFC) principle, the module employs a proprietary Uni-block single-body sensor architecture—integrating coil, magnet, position detector, and feedback control circuitry into a monolithic mechanical-electrical unit. This design eliminates mechanical linkages and hysteresis-prone flexures, delivering intrinsic linearity (<±0.005% FS), long-term stability (drift <±0.01% FS/year), and repeatability better than ±0.002% FS under controlled environmental conditions. Unlike strain-gauge-based load cells, EMFC modules maintain metrological integrity across dynamic loading cycles—including rapid feed-dispense sequences, vibratory conveyor integration, and intermittent batch weighing—without requiring thermal stabilization or zero-tracking algorithms. The YANXIANG series is optimized for embedded integration into PLC-controlled filling systems, gravimetric dosing units, inline quality verification stations, and closed-loop formulation platforms where traceability, audit readiness, and deterministic response time (<100 ms settling to ±0.1 mg) are operationally critical.

Key Features

• Uni-block electromagnetic force sensor: Fully integrated transduction core with active temperature compensation and digital self-diagnostics.
• Compact monolithic housing: 305 × 90 × 97.5 mm footprint enables direct mounting within space-constrained OEM machinery frames.
• Stainless steel enclosure (IP65-rated): Corrosion-resistant 304 SS construction with internal overtravel protection limiting mechanical shock damage up to 500% overload.
• Dual-interface connectivity: Simultaneous DB9 (RS-232/SBI protocol) and USB-C (virtual COM port) enable parallel commissioning and legacy system interoperability.
• Bottom-load configuration: M6 threaded interface supports inverted mounting for hopper-mounted or suspended vessel applications without structural re-engineering.
• Real-time status indication: Tri-color LED provides immediate visual feedback for power-on, calibration mode, overload, and communication handshake states.
• Field-calibration support: External calibration via user-supplied weights (≥1/3 full scale recommended); no proprietary tools or firmware access required.

Sample Compatibility & Compliance

The YANXIANG module is designed for non-destructive, contact-based mass determination of solid, granular, and powdered materials within sealed or open-process vessels. It accommodates standard Ø160 mm stainless steel pans (included) and supports custom pan adapters per ISO 8549-2 for specialized containment requirements. While not certified as a legal-for-trade instrument per OIML R76 or NTEP, its performance characteristics align with ASTM E898–22 (Standard Practice for Gravimetric Measurement in Process Control) and ISO/IEC 17025:2017 clause 6.4.3 for measurement uncertainty evaluation. When integrated with validated host controllers, the module meets data integrity prerequisites for GLP-compliant lab-scale formulation and GMP Annex 11-aligned manufacturing execution systems (MES), particularly when paired with audit-trail-enabled software logging calibrated timestamps, operator IDs, and environmental metadata (temperature/humidity if externally fed).

Software & Data Management

The module operates natively with industry-standard serial protocols—SBI (compatible with Mettler Toledo, Sartorius, and A&D host systems) and SICS (for Beckman Coulter and Thermo Fisher instrumentation ecosystems). ASCII-formatted output includes gross/net/tare values, stability flags, and error codes—all timestamped at source with microsecond resolution. Optional USB-A display interface allows local visualization during setup and troubleshooting without external PC dependency. For enterprise integration, Unicise provides SDK documentation supporting Modbus RTU over RS-485 (optional adapter) and JSON-over-HTTP API wrappers for cloud-based SCADA ingestion. All firmware updates comply with IEC 62443-3-3 security requirements, including signed image validation and secure boot enforcement.

Applications

• Pharmaceutical: Gravimetric powder dispensing in high-shear wet granulation lines and continuous tablet coating systems.
• Food & Beverage: Real-time loss-in-weight (LIW) feeding of spices, enzymes, and functional additives into mixing kettles.
• Chemicals: Closed-loop catalyst dosing in polymerization reactors with <±0.05% mass accuracy per cycle.
• Electronics: Precise solder paste and conductive ink dispensing for PCB assembly with traceable batch records.
• Research Automation: Integration into robotic liquid handlers for solid reagent library management and stoichiometric reaction setup.

FAQ

What is the maximum allowable preload before reaching full capacity?
Preload limits vary by model: UWM16001/A — 5 kg; UWM24001/A — 8 kg; UWM32001/A — 10 kg. Exceeding these values may affect linearity but will not damage the sensor due to built-in mechanical stops.
Can this module operate on battery power?
Yes—when powered by regulated 5 V DC (±5%), it draws ≤120 mA and maintains full specification performance, enabling portable or intrinsically safe deployments.
Is RS-485 communication standard or optional?
RS-485 requires an external converter (e.g., MAX485-based isolator) connected via DB9 pinout; Unicise provides pin-mapping documentation but does not supply the transceiver.
Does the module support automatic internal calibration?
No—it relies exclusively on external calibration to ensure traceability to national standards and avoid drift accumulation from internal reference degradation.
How is environmental temperature compensated?
The Uni-block sensor incorporates dual-point thermal sensing and real-time gain/offset correction using factory-characterized coefficients stored in EEPROM, achieving <±0.001% FS/°C typical sensitivity.
