50kg Aluminum Weighing Load Cell Sensor

50kg Aluminum Weighing Load Cell Sensor — Overview

The 50kg Aluminum Weighing Load Cell Sensor is a compact, high-accuracy sensor designed for reliable weight measurement up to 50 kilograms. Constructed from aluminum alloy, it delivers a strong yet lightweight solution for digital scales, package weighing, robotics, and industrial monitoring.

How it Works

This sensor uses the strain gauge principle integrated in a Wheatstone bridge configuration. When force is applied, the resistance of the strain gauges changes proportionally to the load, producing a small differential voltage. That signal can be amplified and converted to a digital value using an HX711 amplifier or other signal conditioning circuits.

Key Benefits

• High precision and stability because of four matched strain gauges.
• Low drift and consistent readings for long-term use.
• Lightweight aluminum construction for easier handling and mounting.
• Compact footprint with mounting holes for fast integration into custom platforms and scales.

Features and Specifications

• Load capacity: 50 kg.
• Material: Aluminum alloy for strength and low mass.
• Sensing principle: Strain gauge in Wheatstone bridge arrangement.
• Gauge configuration: Four strain gauges for improved accuracy.
• Connection: 4-wire interface labeled E+, E-, A+, A-.
• Recommended amplifier: HX711 or equivalent ADC/signal conditioner for digital output.
• Mounting: Compact design with pre-drilled mounting holes for easy installation.
• Durability: Designed for long service life and stable performance.

Wiring and Interfacing

Typical wiring uses four wires:

• E+ (Excitation +) — supply positive for the bridge.
• E- (Excitation -) — supply negative or ground for the bridge.
• A+ (Signal +) — positive differential output from the bridge.
• A- (Signal -) — negative differential output from the bridge.

For digital projects, connect the signal outputs to an HX711 amplifier module, then connect the HX711 to microcontrollers such as Arduino, ESP32, or a Raspberry Pi (with appropriate level shifting and libraries). Calibrate the system in software to convert raw ADC values to mass units.

Applications

• Digital weighing scales and platform scales.
• Parcel and logistics weighing systems.
• Industrial and laboratory weight monitoring.
• Robotics and automation for force sensing and payload detection.
• DIY electronics projects and prototype development with microcontrollers.

Installation and Calibration Tips

• Mount the load cell on a flat, stable surface and ensure the load is applied at the designed sensing point to avoid off-axis errors.
• Use proper shielding and short wiring runs for signal leads to reduce noise.
• Zero the system unloaded, then apply known calibration weights and record ADC values to compute scale factors.
• Temperature changes can affect readings; allow the system to warm up and perform calibration under typical operating conditions for best results.

Why Choose This Load Cell

This 50kg aluminum load cell sensor offers a balance of precision, durability, and ease of use. Its four-strain-gauge Wheatstone bridge design provides accurate and repeatable measurements, while the aluminum body keeps weight low and simplifies mounting in custom systems.
