WL‑112 Aluminum Alloy Single Point Load Cell, 0.3kg‑5kg High‑Precision Anti‑Side‑Load Weighing Sensor

Product Overview

The WL‑112 is an aluminum‑alloy single‑point load cell designed for ultra‑small weight measurement with capacity coverage from 0.3 kg up to 5 kg. Distinguished by high side‑load tolerance, this strain‑gauge‑based single‑point transducer can tolerate partial off‑center loading better than many conventional miniature load cells. A single WL‑112 unit can operate a small weighing platform without multiple‑sensor grouping, simplifying mechanical assembly for compact micro‑weighing equipment.

This sensor outputs standard Wheatstone‑bridge mV/V analog signals, working cooperatively with weighing transmitters, indicators or signal amplifiers to achieve weight reading, pass‑fail quality checking and closed‑loop filling / batching control. It targets precision micro‑dispensing and small‑package production scenarios across pharmaceutical, cosmetic and food industries.

Key Features

• Elastic‑body made of aluminum alloy, compact form factor for equipment miniaturization
• Wide capacity range: 0.3 kg, 0.5 kg, 1 kg up to 5 kg, dedicated for micro‑weight measurement
• Excellent high side‑load tolerance, reduces measurement error caused by incidental lateral force in automated machines
• Single‑point architecture: one sensor supports small weighing platen, lowers system mechanical cost
• Customizable cable length and other optional specifications to match machine‑building requirements
• Standard M3 threaded mounting holes for fast and reliable integration into automated frames

Industry Note: Even with enhanced side‑load resistance, avoid continuous heavy lateral torque. Persistent side overload may cause plastic deformation of the aluminum elastic element and permanent loss of weighing accuracy. This model is optimized for static micro‑weighing, not for heavy impact dynamic loading.

Typical Applications

WL‑112 is purpose‑built for micro‑dispensing metering, batching, filling and finished‑goods quality‑control for small‑size packages:

1. Precision Batching: Tiny‑ingredient weight monitoring for laboratory‑grade and small‑scale batching systems
2. Micro‑dispensing & Filling: Closed‑loop weight feedback for micro‑dosing, pharmaceutical liquid and cosmetic filling equipment
3. Pharmaceutical Industry: Weight inspection for small sachets, capsules, vials and pharmaceutical finished‑product QC
4. Cosmetic Industry: Weight verification for mini‑size cosmetic bottles, sachets and tube products
5. Food Packaging: Weight checking for light‑weight small food sachets and condiment mini‑packages

Application Tip: For wash‑down hygienic production environments, please consult BRANS for customized protection‑grade options. The standard version is intended for general indoor factory conditions.
