ABB extends to offer new insertion design and larger flow-through options

ABB adds redesigned dual-plate insertion model to its KPM KC7 Microwave Consistency Transmitter offering
New larger flow-through microwave sensor options cater to mill installations that previously could only use insertion types
Update to portfolio provides most representative process pipe consistency measurement on the market

ABB has updated its KPM KC7 Microwave Consistency Transmitter portfolio with a larger flow-through sensor to fit process pipes with a diameter of up to 16”, giving more customers the choice to measure the total consistency of mixed pulps with a flow-through sensor. The technology leader has also launched a redesigned insertion type with a new dual-plate sensor.
Both of the device options will be used in the stock preparation area of mills, which feeds the wet end of the paper machine. The enlarged flow-through model, extending from a previous maximum of 12”, expands ABB’s market reach to those with wider diameter pipes that previously could only use insertion types, but that can now consider both. The larger size, capturing the whole pipe diameter, means the most representative measurement on the market and provides precise, reliable measurements of total consistency regardless of flow rate for superior process control.
For mills opting for the insertion style, the dual-plate design is the only one on the market with an optional temperature sensor that can be retracted for abrasive and unscreened processes, a feature also available with the flow-through model. The parallel antennas avoid microwave reflections in the pipe and generate a self-cleaning effect, removing the risk of obstructions and therefore increasing uptime and reducing maintenance costs compared to other devices.
Microwave measurement is becoming more popular due to its low calibration requirements, high accuracy, and ability to measure total consistency independent of process variables and fiber properties. Unlike optical and sheer force technologies, KPM KC7 is unaffected by both process changes, such as flow speed, pressure and turbulence, and variations in pulp species, fiber length and freeness.
“ABB individually verifies each sensor before implementation to ensure high accuracy, said Karin Hermansson, Product Line Manager at ABB. “With this update to fit larger pipes, reduce obstructions and ensure smooth temperature readings for even the most difficult processes, we can now meet the most diverse requirements in the complex world of papermaking.”
The expansion means that ABB’s KPM KC7 sensor portfolio is now equipped with an added pressure sensor – available as a spare part – to further improve diagnostics. With no moving parts or preventive maintenance requirements, the updated sensors - compatible with third-party couplings for simple upgrades and replacements - make for easy operation and maintenance to ensure a low total cost of ownership.
The application usage extends across paper, tissue, board and pulp producers, from recycled pulping to end of machine stock preparation, and can even be used for municipal and industrial wastewater. KPM KC7 is particularly good for users of recycled raw material and pulp and paper mill teams that prefer to measure and control total consistency with microwave technology.
