20Kg Load Cell

20Kg Load Cell

₹95.00Price

📌 Overview

The 20Kg Load Cell is a weight/force sensor that measures loads up to 20 kilograms.

👉 It is widely used in:

  • ⚖️ Digital weighing scales

  • 🤖 Force measurement systems

  • 🏭 Industrial automation

  • 🧪 Smart IoT weighing projects

🧠 Working Principle

The load cell works using the concept of Strain Gauge:

  • Inside → metal beam with strain gauges

  • When weight is applied → beam deforms slightly

  • This changes electrical resistance

  • Output → very small voltage signal (mV range)

👉 Requires an amplifier like HX711 to read values
