I AM FAST SIMPLE DIGITAL INTEGRATED KROHNE SAMSON FOCUS-1

Developed for the process industry

BASED ON PROVEN COMPONENTS

FOCUS-1 is developed for the process industry and features a integrated control valve, flowmeter, pressure and temperature sensors combined with extensive computing power in one single device.

DESIGNED FOR HIGHEST ACCURACY

Extensive CFD analyses enables FOCUS-1 to measure and control a medium between the identical face to face dimensions without jeopardizing on performance compared to a conventional control loop.

MAXIMUM PROCESS AND COSTS TRANSPARENCY

Traditional installations for control tasks in process plants usually consist of several sensors, a control valve and a DCS with control algorithms. The process operator relies on proper functioning of all these components to ensure process quality.

By combining all these components in one device, FOCUS-1, specifically developed for the process industry, simplifies the installation dramatically and reduces significantly the number of flanges, cables and I/O points. In addition to the above, the commissioning efforts are also heavily simplified, as all the control algorithms are implemented within FOCUS–1.

CLICK & CONNECT

Following the standard

FOCUS-1 complies with various communication protocols which are currently used in the process industry. Both setpoint, measured values as well as alarms can be communicated trough industry standard protocols. This allows the user seamless integration in their existing automation infrastructure.

Easy and intuitive interface

FOCUS-1 can be easily accessed via its in-build web address. This allows remote access, user-friendly interfaces, cross-platform compatibility, scalability, and security, offering several advantages for asset management, maintenance and data control.

FOCUS-1 simplifies & Improves control

Internal communication between components reduces the need for complex DCS systems. FOCUS-1 can be used depending on control requirements allowing flexibility and adaptivity in various applications. With 1 device any of the below control options can be selected. By using FOCUS-1 as process controller (2) or system controller (3) the build-in PID-(auto) tuner guarantees simple and accurate process control.

INTELLIGENT DIAGNOSTICS

IMPROVE PLANT UPTIME

The compute model in FOCUS-1 is enhanced with an additional layer of process monitoring, alarming, and diagnosis without compromising safety or performance. This is called the Digital Twin and constantly monitors deviations between measured and modelled values in the compute model. When a deviation of the measured value appears, the device triggers an alarm with information on the possible cause and severity. In the meantime, FOCUS-1 will present the modelled value which allows in having a replaceable process value to continue with operations. Resulting in opportunities to extend and plan maintenance to stops or maintenance beneficial moments.
