📊 Technical Specifications & Performance

Here are the key technical details of the Zemic L6E3:

These specs help you match the L6E3 to your application and ensure it operates reliably.

🛠 Wiring & Connection

Standard 4-Wire Wiring

The L6E3 uses a typical 4-wire connection:

• Red → Excitation + (E+)

• Black → Excitation – (E−)

• White → Signal – (S−)

• Green → Signal + (S+)

Shielded cable is used, and the shield is usually connected to the element or ground. zemiceurope.com+1

Cable & Shielding

• Cable: 4-conductor, shielded, typically PVC jacket. zemiceurope.com+1

• Standard cable length: usually 3 meters. zemiceurope.com+1

• Use twisted pair wires for signal +/− to reduce noise.

• Ensure good grounding of shield to prevent interference.

🏗 Installation & Mounting Tips

1. Platform Size & Centering
   Keep platform dimensions within 450 × 450 mm to avoid excessive side error. zemiceurope.com+1

2. Fixation Torque
   For fixation bolts: M8 bolts torque ~ 25 Nm. zemiceurope.com+1

3. Edge Balancing
   The L6E3 is often edge-balanced by the manufacturer, meaning side error is reduced. zemiceurope.com+1

4. Avoid Side Loads & Moments
   Ensure vertical loading only. Side forces or torques degrade accuracy.

5. Temperature Effects
   Because aluminum can expand with temperature, maintain uniform temperature across the load cell and avoid large gradients.

6. Protect Against Harsh Environments
   With IP65, it’s safe for many industrial settings, but avoid direct water jets or submersion.

🏭 Applications & Use Cases

The Zemic L6E3 serves in many weighing systems:

• Retail / POS scales

• Bench scales / laboratory balances

• Counting & checkweighing systems

• Packaging & filling machines

• Industrial floor scales for light to medium loads

• Small hopper weighing systems

Its design makes it appealing where moderate capacity and compact size are needed.

💡 Tips to Get the Most Out of the L6E3

• Always calibrate after installation using certified weights.

• Use proper signal amplifiers or weighing controllers supporting 2 mV/V signals.

• Perform zero tracking if your setup allows it, to compensate for drift.

• Periodically verify the load cell’s performance under known loads.

• Ensure cable routing is away from motors, relays, or sources of EMI.
