What is NeSSI™?

The New Sampling/Sensor Initiative aims to make significant improvement to the design and operation of on-line analyser systems.

The driving forces behind the initiative are economic: NeSSI™ will make analyser systems less expensive and they will give a better pay back.

Goals How
To reduce the cost to build
  • Standardisation, reducing design and engineering time.
  • Simplified assembly, reducing manufacturing costs.
  • Less field infrastructure, reducing construction costs.
To reduce the cost to operate
  • Faster, easier predictive maintenance, reducing technician time.
  • Remote connectivity, reducing engineering support time.
  • Smart diagnostics, improving maintenance efficiency.
To increase the credits
  • Higher reliability, delivering valuable data for more of the time.

The elements of a NeSSI™ system

The substrate provides the channels through which samples flow and the mechanical platform on which sample system components, sensors and analysers are mounted.

The NeSSI™-bus provides networked connectivity to components and sensors mounted on the substrate.

The Sensor Actuator Manager (SAM) is the interface between the NeSSI™-bus and EtherNet. It enables process measurements with their validity codes to be seen by a Distributed Contol System (DCS) and it enables maintenance-related data to be viewed from remote locations. SAM also includes smart functionality for advanced diagnosis of system health. Remote control of the sample system, for example valve switching is also available via the NeSSI™-bus and SAM.
