Curiotec Digital Load Cell Solution
Digital Load Cell Solution for Truck Scales
RS-485 digital weighing technology for truck scales, weighbridges, silo scales, and other high-capacity industrial weighing systems.
OIML C3 / OIML C6 | IP68 | RS-485 | Digital A/D Module
Ultra-small Digital A/D Module
The digital A/D module converts analog strain-gauge signals into RS-485 digital data close to the sensing point. This helps improve signal stability, reduce noise influence, and simplify service work in truck scale installations.

Digital Truck Scale Configuration
Integrated RS-485 Digital Weighing Architecture
A digital truck scale system combines digital load cells, a digital junction box, digital indicators, remote display, and PC/PLC integration. RS-485 communication supports long-distance transmission and easier individual load cell diagnostics.
- Digital Load Cells: provide digital data from each weighing point.
- Digital Junction Box: collects RS-485 signals and supports stable transmission.
- Digital Indicator / Software: supports calibration, diagnostics, display, reports, and automation connection.
Key Advantages for Truck Scale Projects
- Stable signal transmission: RS-485 helps reduce noise impact over long cable distances.
- Faster commissioning: digital corner adjustment and calibration can reduce setup time.
- Smarter maintenance: individual load cell monitoring helps locate overload, cable, or sensor issues faster.
OIML C3 and C6 Certified Accuracy
Curiotec load cells are available with OIML C3 and OIML C6 accuracy options. The correct class should be selected according to capacity, division value, number of load cells, indicator compatibility, calibration method, and operating environment.
| OIML C3 Suitable for commercial truck scales and industrial weighing systems requiring reliable legal-for-trade performance with practical investment cost. | OIML C6 Higher accuracy class for demanding weighbridge, railway, silo, and vehicle weighing applications. |
Heavy-duty Outdoor Performance
Truck scales operate under axle load, vibration, rainwater, dust, and electrical noise. Curiotec load cells with IP68 protection are suitable for outdoor weighbridge environments, wet pits, silo weighing, railway scales, and other high-capacity applications.
Common Curiotec Models
Analog or Digital Load Cell?
| Option | Recommended when |
|---|---|
| Analog load cell | The project needs reasonable cost, easy replacement, and compatibility with standard weighing indicators. |
| Digital load cell | The truck scale has long cable distances, electrical noise, faster calibration requirements, or individual diagnostics needs. |
