WL‑111 Aluminum Alloy Single Point Load Cell, 2‑50kg High‑Precision Force Sensor

Product Overview

The WL‑111 is a single‑point load cell constructed from aluminum alloy, with capacity options ranging from 2 kg to 50 kg. As a classic beam‑type force‑sensing component for low‑load applications, single‑point load cells feature inherent off‑center load tolerance. A single unit can support a small‑size weighing platform without combining multiple load cells, greatly simplifying mechanical design for compact scales.

Optimized for light‑duty automated industrial weighing, this model collects weight data for batching, filling and small‑item quality‑control processes. It outputs standard millivolt‑per‑volt (mV/V) bridge analog signals, compatible with weight transmitters and weighing indicators for weight display, alarm trigger and closed‑loop process control.

Key Features

• Aluminum alloy elastic‑body structure, compact dimension (52×12.7 mm), saves installation space for machine integration
• 0.02% F.S. combined error, consistent non‑linearity and repeatability for precision micro‑weighing
• Single‑point mechanical design: one sensor can operate a small weighing platen, lowering mechanical complexity and total system cost
• Customizable cable length; IP65 protection class available upon request for normal dusty or humid workshop environments
• Standard mounting threaded holes (M3 & M4), for direct assembly on automated machine frames
• Wide operating temperature from ‑20 °C to 60 °C, mitigates measurement drift caused by factory ambient‑temperature variation

Industry Note: Small‑capacity aluminum single‑point load cells are designed for static weighing. Avoid continuous heavy shock loading. Safe overload is 150 % F.S. Sustained over‑loading will create permanent plastic deformation of the elastic body and irreversible accuracy loss.

Typical Applications

The WL‑111 is engineered for micro‑weighing and small‑batch production across multiple industries:

1. Material Batching: Weight monitoring of minor ingredients in small batching systems
2. Liquid Filling & Dispensing: Closed‑loop weight feedback for pharmaceutical and cosmetic filling equipment
3. Micro‑dispensing: Weight measurement for precision micro‑dosing machines
4. Pharmaceutical Industry: Weight inspection for sachets, vials and finished‑product quality control
5. Cosmetic Industry: Weight verification for small bottles and tube‑packed cosmetic products
6. Food Packaging: Weight checking for sachet‑format food and condiment packages

Application Tip: Standard IP65 rating defends against spray splashing but is not suitable for high‑pressure direct water jet washing. Request upgraded ingress protection for frequent wash‑down hygiene‑critical sites.
