Refer to the outline dimension diagrams for precise measurements and bolt hole patterns for your specific load cell capacity:
- 10T-20T Range: See Figure 5.2 for dimensions A, B, C, D, E, H.
- 30T Range: See Figure 5.3 for dimensions A, B, C, D, E, H.
- 40T-100T Range: See Figure 5.4 for dimensions A, B, C, D, E, H.

6. Operating Instructions
Once installed and wired, the load cell will provide an analog output signal proportional to the applied force. This signal needs to be processed by a compatible weighing indicator or controller.
- Power On: Apply DC 5-15V power to the load cell via the Exc+ and Exc- terminals.
- Calibration: Perform a system calibration according to the instructions of your weighing indicator. This typically involves setting zero and span with known weights.
- Measurement: Apply the load to be measured. The load cell will output a signal (mV/V) that the indicator converts into a weight reading.
- Monitoring: Continuously monitor the readings. Ensure the applied load does not exceed the safety overload (150% R.C.) or extreme overload (200% R.C.) to prevent damage.

7. Maintenance
7.1 General Maintenance
- Regularly inspect the load cell and its mounting for any signs of physical damage, corrosion, or loose connections.
- Ensure the environment remains within the specified operating temperature range (-20°C to 80°C).
- Keep the load cell clean and free from debris that could affect its performance.
7.2 Storage
When not in use for a long time, it is recommended to keep the original packaging and seal the interface to protect against dust and moisture. Store in a dry, non-corrosive gas environment with temperatures between -20°C and +70°C.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No output/Incorrect reading | Incorrect wiring, power supply issue, damaged cable, load cell overload. | Check wiring against diagram (Figure 5.5). Verify power supply voltage. Inspect cable for damage. Ensure load is within capacity. |
| Unstable readings | Loose connections, mechanical instability, electrical interference, temperature fluctuations. | Tighten all connections. Ensure stable mounting. Shield cables if necessary. Check operating temperature. |
| Load cell not responding | Complete failure, severe overload, internal damage. | If all other troubleshooting fails, the load cell may be damaged. Contact support for replacement or repair. |
9. User Tips
- When planning a weighing system, consider using multiple load cells (e.g., 4 load cells for a tank) to distribute the load and improve accuracy, especially for larger capacities.
- Always ensure the load cell is properly calibrated with your specific weighing indicator for optimal performance.
- For critical applications, periodic re-calibration is recommended to maintain accuracy over time.
