Connection example

NU Series network communication units can be used to connect N-bus–compatible pressure sensors.

  • Using N-bus–compatible devices makes it possible to connect different models together.
  • Up to 16 sensors can be connected to a single communication unit.

Typical connection example

Using an NU Series communication unit makes it possible to collect and manage various information from N-bus–compatible pressure sensors. This allows for the construction of information systems for batch monitoring of pressures at various locations, predictive maintenance, changeovers, quality management, and more.

The following example includes network-connected pressure sensors.

Real-time monitoring of suction pad wear

Monitoring the pressure values makes it possible to check suction pad wear conditions without the need for periodic inspections.
Optimizing suction pad replacement timing can help reduce the time and costs spent on maintenance.
