The Most Widely Used Load Cell Connection

A Load Cell 4 Wire is the most common wiring configuration used in weighing systems worldwide. These load cells have two wires for excitation (power input) and two wires for signal output. This simple setup makes them cost-effective, reliable, and easy to integrate with controllers, amplifiers, and microcontrollers.

At Sensors and Gauges, we supply 4 wire load cells for a wide range of applications — from bench scales and industrial platforms to OEM equipment and DIY electronics.

How Does a 4 Wire Load Cell Work?

A 4 wire load cell typically consists of:

• 🔴 + Excitation (E+) – Power input (usually red)

• ⚫ – Excitation (E–) – Ground return (usually black)

• 🟢 + Signal (S+) – Output voltage (usually green)

• ⚪ – Signal (S–) – Output reference (usually white)

When load is applied, the internal strain gauges change resistance, producing a millivolt-level signal proportional to the weight. This signal can then be amplified and processed by a controller or ADC (Analog-to-Digital Converter).

Applications of 4 Wire Load Cells

The 4 wire configuration is used in most weighing systems, including:

• ⚖️ Bench & Retail Scales – Compact and low-capacity weighing

• 🏭 Industrial Platforms – For conveyors and process weighing

• 🚚 Vehicle & Truck Scales – Heavy-duty load measurement

• 🧪 Laboratories – Precision instruments and testing rigs

• 🏠 DIY Electronics – Arduino, Raspberry Pi, and ESP32 projects

Difference Between 4 Wire and 6 Wire Load Cells

• 4 Wire Load Cells – No sense wires; cable length or temperature changes can cause minor drift.

• 6 Wire Load Cells – Include sense wires to compensate for voltage drops in long cables; ideal for large-scale or industrial applications.

For most bench scales and general weighing, a 4 wire load cell is sufficient. For high-capacity, long-distance wiring, a 6 wire load cell is recommended.
