This 50kg load cell is a strain gauge based force and weight transducer designed for higher capacity measurement systems. Manufactured from aluminum alloy, it converts mechanical force and pressure into a proportional electrical signal for accurate weight detection in digital scales, industrial automation systems, and embedded electronics projects.

This 3-wire load cell is commonly used in bathroom scales and platform scale designs where multiple sensors are combined to measure larger total loads.

Specifications

• Rated capacity: 50kg per sensor
• Sensor material: Aluminum alloy
• Dimensions: 34mm x 34mm x 7.8mm
• Strain gauge based force and pressure sensing element
• 3-wire half-bridge configuration

Wiring

Bridge Configuration Options

Single Sensor Configuration

• Use one sensor with an external precision resistor to form a full-bridge measurement circuit.
• Measuring range: 50kg.
• External resistor selection affects measurement stability and accuracy.

Two Sensor Configuration

• Use two 50kg sensors to form a full-bridge measurement.
• Total measuring range: 50kg x 2 = 100kg.

Four Sensor Configuration

• Use four 50kg sensors to form a complete full-bridge platform scale system.
• Total measuring range: 50kg x 4 = 200kg.
• This configuration is commonly used in bathroom scales where one sensor is placed at each corner.

Applications

• Bathroom scales
• Platform weighing scales
• Industrial batching systems
• Material handling and warehouse weight monitoring
• Custom Arduino and ESP32 weight measurement projects

Because this is a half-bridge load cell, it requires bridge completion before connecting to a signal amplifier. For digital measurement and calibration, pair with the HX711 Load Cell Amplifier.
