Low life cycle costs with the DIWA SmartNet Bus Monitor

Voith helps fleet operators to realize low maintenance and repair costs while simultaneously maintaining high vehicle availability.

Due to their central position, automatic transmissions are important interfaces in vehicles and can be used to capture operating data without additional sensors. In order to utilize this data efficiently, reliable and quick access is necessary.

The DIWA SmartNet Bus Monitor enables simple and fast access via the Internet. This means the operator has an overview of all relevant vehicle data.

DIWA SmartNet makes it possible to realize low costs for maintenance and repairs while simultaneously maintaining high vehicle availability. At the same time, the operator is optimally informed about the condition of the Voith transmission and thus provided with a simple and efficient way of monitoring.

Advantages of the DIWA SmartNet Bus Monitor:

  • Permanent status monitoring via key parameters
  • Fast identification of the condition of the transmission with the help of traffic light display system
