Product Description:
WLSM‑135 is a compact integrated single‑point weighing module purpose‑built for mg‑level micro‑volume industrial weighing. Constructed from high‑strength aluminum alloy, this strain‑gauge‑based unit delivers outstanding metrological performance with combined error down to ≤0.015%F.S, enabling reliable high‑resolution measurement for micro‑dosing and small‑batch filling workflows.
Integrated mechanical overload protection safeguards internal sensing elements from accidental over‑range impact during automated production cycles. Its streamlined monolithic mechanical layout simplifies OEM embedding; pre‑drilled mounting holes permit fast bolt‑down installation into automated machinery without complex modification.
Delivering stable analog Wheatstone‑bridge output, WLSM‑135 maintains exceptional long‑term measurement stability even under continuous automated operation. The shielded 5‑core signal cable resists electromagnetic interference on production floors. Optimized for space‑constrained machine designs, this module becomes the ideal embedded weighing core for pharmaceutical dispensing, cosmetic formulation, fine‑food small‑package filling and inline production quality‑control stations.
Features:
- Mg‑level ultra‑high resolution: Specially engineered for micro‑quantity weighing, combined error ≤0.015%F.S for demanding precision requirements
- Compact space‑saving footprint: Slim integrated‑module construction, well‑suited for installation inside compact automated equipment with limited mechanical space
- Built‑in mechanical overload safeguard: Integrated limit‑stop structure defends sensor against shock load and accidental overloading on production lines
- Robust aluminum‑alloy housing: Light‑weight yet rigid monolithic body, guarantees mechanical stability for long‑term cyclic automated weighing
- Excellent long‑term stability: Low signal drift during continuous operation, consistent readings for round‑the‑clock batch‑production weighing tasks
- Simplified OEM integration: Pre‑processed mounting hole layout for direct bolt‑on assembly, no extra adapter modification required
- Anti‑interference shielded wiring: Complete Wheatstone‑bridge configuration with shielded cable, reduces EMI noise in factory automation environments
- Optimized for micro‑dispensing workflows: Tailored for low‑capacity batching, filling and check‑weighing of small‑dose products
