FOCUS-1 – Smart process node for the process industry 4.0

FOCUS-1 is the first intelligent process node specifically developed for the process industry 4.0. This multifunctional smart flow control instrument – developed by FOCUS-ON, a SAMSON and KROHNE company – combines sensors, actuator and control functionality in one device. By measuring flow, pressure and temperature simultaneously and regulating its valve function independently, all specified set points can be accurately and reliably achieved. In this way, the device acts as an autonomous actuator for decentralised control tasks. There is no need to establish complex control loops or connect with a DCS. This makes FOCUS-1 the ideal smart control unit for the autonomous factory. It is equally suitable for process industry 4.0 applications in greenfield projects as well as process automation in existing brownfield applications. The process node can also be used as a drop-in replacement of conventional valves to increase diagnostic capability.

FOCUS-1 features extensive diagnostics. It knows its current status, can predict future conditions, and is capable of learning so as to adapt to process applications. Thanks to its “smart cavitation control” feature, FOCUS-1 is able to identify, monitor and alarm different kinds of cavitation caused in a pipeline. In this way, operators are enabled to carry out predictive maintenance measures to avoid increased stress and wear of valve and piping ahead of time as well as to prevent unplanned downtime. Due to its advanced algorithms, the smart flow controller can also create a "digital twin". This allows modelling the measured data in such a way that device function and operation can be maintained even in the event of a sensor failure. With the help of the digital twin, plant operators implement redundancy and thus permanently increase the reliability, safety and availability of their plant.

The combination of sensors, valve and controller with extensive diagnostic features translates into less engineering effort, reduced sourcing and installation costs, a more simple and compact measuring set-up as well as more efficient life cycle management and maintenance. This simplifies processes, reduces system complexity and sustainably reduces capital expenditure (CAPEX) and operational expense (OPEX).
