Most of the Profibus-PA measuring devices from Krohne are designed and certified according to Profile B, Version 2,0, the Coriolis mass flowmeter to Version 3.0. The 10 mA base current is optimal for the maximum number of stations. The fault disconnect electronics (FDE) unit ensures very high network security.
All Profibus-PA measuring devices from Krohne support the Siemens PDM operating tool (Process Device Manager). First applications have already been successfully implemented with this vendor-independent tool used for parameter assignment, diagnostics, etc.
On request, the Profibus-PA measuring devices from Krohne are equipped with an additional (binary) output or input, eg current output for displaying the level from the tank bottom or pulse output for totalling mass flow or volumetric flow.
Fields of application for the Profibus-PA measuring devices from Krohne are the chemical, petrochemical, pharmaceutical, bio-engineering and food industries, the energy industry, as well as water and wastewater treatment.
IFC 090 signal converter for electromagnetic flowmeters
The IFC 090 is of a modular design and can be operated together with all electromagnetic flowmeters from Krohne that are either of compact or separate design. The Profibus-PA is also available as an intrinsically safe version for use in hazardous areas.
High reliability and safety, good repeatability and accuracy, as well as its wide range of application, including pulsating flow applications directly behind positive-displacement pumps, are some of the features that characterise the high standard of quality of the IFC 090 signal converter. As a result, various large chemical companies have declared the IFC 090 to be the instrument standard, says Krohne.
MFC 081 and MFC 085 signal converter Corimass mass flowmeters
Corimass mass flowmeters are designed to measure independent of density, pressure, temperature and viscosity of the liquid product. The devices are available with a single curved tube or parallel curved tubes and also with a straight single tube. Depending on its design, the device can measure gases, liquids and also gas-laden liquids. Meter sizes are available for liquid products from 0,006 to 3000 kg/min.
The straight-tube meter is particularly suitable for precise dosing, for batching processes and for measurement of minimal flowmeters.
All devices are available as compact or separate systems. Further options are a high-pressure version, hazardous-duty versions and a heating facility.
BM-70 - the device for noncontact level measurement
The measuring devices of the BM 70 A/P series use microwave technology for the continuous and noncontact level measurement of liquids, pastes, slurries, particulates and liquid gases, also under extreme conditions, eg liquid metals.
The device is mounted directly on eg a tank fitting. Available for long-distance data transmission are a 4 to 20 mA current output with superposed digital smart signal and a digital interface for connection of indicating instruments, recorders, controllers and limit switches as well as process control systems.
Further options are a high-temperature version, versions for use in hazardous areas and systems with heating, cooling and antenna purging.
Why secure industrial communication depends on deployment as well
Fieldbus & Industrial Networking
The Industrial Security Harmonisation Group has released a joint industry perspective highlighting a critical truth in industrial cybersecurity: secure communication is not determined by protocols alone, but by how they are deployed and managed in real-world environments.

The introduction of TwinCAT in 1996 marked a decisive evolutionary step for PC-based control. Today, the TwinCAT platform combines all automation functions in a strictly deterministic real-time environment, from PLC and motion control through CNC and measurement technology and beyond, to vision, robotics and pioneering AI tools.

Feedforward control is a powerful technique that can dramatically improve control variance in cases where load changes cause big deviations from setpoint and the actual process dynamics are too slow to allow the feedback controller to operate fast enough to catch these disturbances.
