WL‑113H High‑Accuracy Single Point Load Cell, mg‑Level Resolution With Built‑in Overload Protection

Product Overview

The WL‑113H is a high‑precision aluminum‑alloy weighing load cell designed for micro‑volume weighing applications. It features built‑in integrated overload protection structure, outstanding long‑term stability and mg‑level measurement resolution, making it an ideal transducer for ultra‑fine weight acquisition.

Different from general miniature load cells, the internal mechanical overload stop limits excessive deformation of the elastic body, greatly lowering the risk of permanent damage caused by accidental over‑loading during daily operation. It outputs standard Wheatstone‑bridge mV/V analog signals. When matched with high‑resolution weighing transmitters or digital indicators, it realizes weight reading, material batching control, filling closed‑loop regulation and finished‑product quality inspection. It is widely deployed in micro‑dispensing, pharmaceutical, cosmetic and small‑package food production lines.

Key Features

• Compact mechanical structure, simple and fast on‑site installation
• Integrated built‑in overload protection: mechanical stop structure prevents elastic‑body over‑deformation under accidental overload
• Outstanding high‑precision performance, delivers mg‑level resolution for ultra‑micro weight detection
• Excellent long‑term signal stability, reduces frequent recalibration workload for precision production equipment
• Capacity range covers ultra‑light loads: 50g /100g /200g /300g /500g
• Suitable for high‑demand micro‑batching, micro‑filling and small‑goods quality‑control scenarios

Industry Note: mg‑resolution load cells belong to high‑sensitivity precision measuring components. External vibration, airflow and temperature fluctuation will directly affect weighing stability. Anti‑vibration mounting and draft‑proof measures are strongly recommended for best measurement performance. Even with integrated overload protection, intentional heavy overload or impact shock should still be avoided, as protective mechanism only serves for accidental transient over‑load protection.

Typical Applications

WL‑113H is optimized for micro‑volume high‑precision weighing, covering batching, filling and production quality‑control processes:

1. Micro‑precision Batching: Trace ingredient dosing & weight monitoring for laboratory and small‑batch formulation equipment
2. Micro‑dispensing & Filling: Closed‑loop weight feedback for ultra‑fine dosing of pharmaceutical reagents, essence and cosmetic raw materials
3. Pharmaceutical Industry: Weight inspection for tiny medicinal sachets, micro‑capsules, reagent vials and pharmaceutical finished‑product QC
4. Cosmetic Industry: Weight verification for mini samples, trial‑size sachets and micro‑packaged skincare products
5. Food Packaging: Weight checking for ultra‑light seasoning sachets and miniature food portion packages
