WLSM‑131 Mg‑Level High‑Precision Weighing Module Integrated Overload‑Protected

Product Description:

The WLSM‑131 is a compact, strain‑gauge‑based single‑point weighing module purpose‑built for demanding milligram‑level micro‑volume industrial weighing. Manufactured from high‑strength lightweight aluminum alloy, this integrated unit merges precision sensing mechanics with built‑in mechanical overload stop protection to defend against accidental over‑range damage during automated production operations.

Covering capacities from 200 g up to 5 kg, it delivers outstanding measurement performance with combined error, non‑linearity and repeatability all ≤0.01% F.S., guaranteeing consistent, traceable weight readings for fine dosing scenariosBrans Meas.... Boasts ultra‑small nominal displacement below 0.4 mm and broad operating temperature span of ‑40 °C ~ +85 °C, enabling reliable operation across variable factory environmental conditions.

Supports 2‑12 VDC excitation with standard analog Wheatstone‑bridge output (~2.0 mV/V). Pre‑drilled mounting holes simplify OEM machine embedding, perfect for integration into filling equipment, batching stations, inline quality‑check machinery and automated micro‑dispensing systems. Custom‑length cable and enhanced protection class options are available to match unique system integration requirements.

Features:

• • Mg‑grade ultra‑high precision: Combined error, non‑linearity & repeatability ≤0.01% F.S., delivers stable milligram‑resolution measurement for micro‑quantity weighing tasksBransloadc...
  • Built‑in integrated overload protection: Mechanical stop structure provides 150% F.S. safe overload capacity, preventing sensor damage from impact or accidental overloading
  • Wide capacity portfolio: Multiple measuring ranges: 200 g / 300 g / 500 g / 1 kg / 2 kg / 3 kg / 5 kg for diverse small‑load application needs
  • Robust aluminum alloy monolithic housing: Light‑weight, rigid mechanical structure, low nominal displacement (<0.4 mm), minimizes mechanical drift under continuous cycling
  • Extreme temperature adaptability: Operating range ‑40 °C to 85 °C, maintains accurate output under cold or high‑temperature workshop surroundings
  • Excellent electrical performance: ≥5000 MΩ@100 VDC insulation resistance; low zero‑balance deviation ±0.05 mV/V; standard 2.0 mV/V sensitivity analog bridge signal
  • OEM‑friendly mechanical layout: Pre‑machined mounting holes for fast installation into automation equipment; shielded 5‑core signal cable (4 m standard, customizable length) for noise‑resistant signal transmission
  • Compact all‑in‑one module design: Ready‑to‑use weighing unit without complicated auxiliary mechanical parts, shortens equipment development cycle for system integrators
