Digital Load Cell KDS-D 30tf | Camasitec Technology

CASC KDS-D / KDB-D is a digital double-ended shear beam load cell built for truck scales, railway scales and silo weighing systems. The load cell converts the weighing signal to digital data close to the sensing point, then transmits it over RS-485 communication for improved stability on long cable runs.

With OIML C4 accuracy and a rugged double-ended shear beam construction, this load cell is suited to heavy industrial weighing sites that need both mechanical durability and reliable digital diagnostics.

Key Advantages

Digital signal processing reduces electrical noise and improves stability, and supports checking each load cell in the system individually.

RS-485 communication suits truck scales, silo scales and installations with long cable distances between load cells and indicator.

Double-ended shear beam construction provides strong mechanical stability for heavy-duty truck scale loading.

OIML C4 accuracy class supports industrial and trade-oriented weighing requirements.

Suitable for retrofit and upgrade projects replacing older digital load cells, subject to compatibility checks with the existing indicator.

Replacement and Installation Notes

Do not replace individual load cells directly without first checking communication protocol compatibility and the indicator’s ability to recognize the new digital load cell.

Replace load cells as a matched set on the same platform to avoid mismatched communication standards, sensitivity, or addressing.

After installation, assign load cell addresses, check each corner, perform zero and span calibration, and record final parameters.

KALA supports indicator configuration review, load cell selection and recalibration guidance for truck scale upgrades.
