Electra Weighing Systems (EWS)
ISO 9001:2015 certified engineering pioneer specializing in high-accuracy industrial weighing machines, digital strain gauge load cell technology, dynamic inline checkweighers, hopper batching rigs, and custom SPM automation.
Pioneering Heavy Industrial & Automated Weighing Solutions
Founded with a mission to deliver zero-error mass measurement across process manufacturing, Electra Weighing Systems (EWS) designs bespoke weighing systems for pharmaceutical cleanrooms, chemical batching plants, agricultural grain processing mills, and heavy metal foundries.
By combining IP68/IP69K hermetically sealed stainless steel load cells, ultra-fast 4800Hz digital ADCs, and custom PLC/SCADA control algorithms, EWS machines ensure legal-for-trade OIML Class III & NTEP accuracy under extreme thermal and mechanical vibration conditions.
Full Explanation of Electra Weighing Systems (EWS) Technology
1. High-Accuracy Digital Load Cell Sensor Network
EWS utilizes premium strain-gauge and quartz piezo load sensors capable of micro-gram sensitivity. Each cell is coupled to an EWS multi-channel digital transducer that performs active temperature compensation, anti-vibration FFT filtering, and zero-point drift suppression.
2. Dynamic High-Speed Inline Checkweighers
Built for high-volume production lines, EWS dynamic weighers weigh items on moving belts at speeds exceeding 220 packs per minute with a standard deviation under ±0.1g. Integrated rejection mechanisms (pneumatic arm, air blast, drop belt) eliminate non-conforming items instantly.
3. Automated Batching, Hopper & Silo Systems
EWS Loss-in-Weight and Gain-in-Weight micro-dosing systems meter precise ratios of powders, liquids, and bulk solids. Outfitted with electro-pneumatic slide gates, screw feeders, and pneumatic vibrators, EWS hoppers deliver repeatable ingredient blending.
4. Industry 4.0 Telemetry & ERP Integration
Every EWS weighing terminal supports Ethernet/IP, Profinet, Modbus TCP, and OPC UA protocols. Real-time batch logs, weight histograms, and calibration audit trails are pushed automatically to SAP, Oracle ERP, or cloud monitoring dashboards.
