Load Cell Pendeo® Truck Digital weighing technology for reliable vehicle weighing
The digital load cells in the Pendeo® Truck series are specially designed for vehicle weighing. They are designed such that, when combined with mounting kits, they can compensate for movement of the bridge structure. In combination with “DAT – Digital Assistance Technology” from Minebea Intec, the Pendeo® Truck also allows for the recording of valuable data about the weighing process.
Proven Minebea Intec technology for a wide range of applications
- Robust design ensures insensitivity to vibration and enables load capacities from 20 to 75 tonnes.
- Faster commissioning and shorter service times thanks to digital data processing
- High corrosion resistance due to high quality steel alloys ensures extremely long service life
- Perfectly matched weighing electronics complete the digital measurement chain.
