YZC-133 20kg Load Cell Weighing Sensor – High Precision Aluminum Alloy Scale Sensor for Arduino

Overview 

The YZC-133 20kg Load Cell is a high-precision “Parallel Beam” strain gauge sensor. Manufactured from a premium aluminum alloy, it is designed to measure weights up to 20kg with consistent accuracy. It works on the principle of a Wheatstone Bridge—as weight is applied, the electrical resistance changes slightly, which can be read by a microcontroller. It is the perfect heart for any DIY smart scale, inventory tracking system, or industrial weighing project.

Key Features 

• High Sensitivity: Capable of detecting minute changes in weight when properly calibrated.

• Rugged Construction: Made from aviation-grade aluminum alloy with an IP65 protection rating against dust and light moisture.

• Four-Wire Interface: Standard color-coded wiring (Red, Black, White, Green) for easy connection to an HX711 module.

• Pre-Drilled Holes: Comes with M4/M5 threaded mounting holes for easy installation on a base or platform.

• Temperature Compensated: Designed to maintain accuracy even with slight changes in ambient temperature.
