In this next generation moisture measurement system, Brookhuis uses state-of-the-art electronics.

The heart of the FMI-IV system is a "real-time" and "open" PLC system from Phoenix with an INTERBUS field bus with fibre optical connections. With the integration of the INTERBUS field bus in the Brookhuis sensors and control unit, new functions such as remote access and remote servicing as well as simple and fast network facilities are available. Up to 10 FMI-IV sensors can be connected to one control unit. Also other devices based on the INTERBUS field bus can integrated fast and with low costs. A FMI-IV system can be upgraded with optional density measurement for improved accuracy and dimensions measurement for versatility. Remote access, network facility and industrial PC with touch screen are also available options.

  • The open fieldbus system INTERBUS for modern automation uniformly links all the process peripherals with all common controllers. With the serial bus cable, it is possible to network sensors and actuators, control machines and systems, network production cells and connect higher-level systems, such as control rooms.

FMI-IV comes with a Windows based operating software for easy access and operating.
