ABB expanded its KPM KC7 Microwave Consistency Transmitter portfolio with a larger flow-through sensor to fit process pipes with a diameter of up to 16 inches. According to the company, this gives more customers the choice to measure the total consistency of mixed pulps with a flow-through sensor. The company has also launched a redesigned insertion type with an improved dual-plate sensor.

Both 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 extends from a previous maximum of 12 inches. This expands ABB’s market reach to those with wider diameter pipes that previously could only use insertion types, but can now consider both.


For mills opting for the insertion style, the new dual-plate design comes with an optional temperature sensor that can be retracted for abrasive and unscreened processes. This feature is 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.

“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. The updated sensors are compatible with third-party couplings for simple upgrades and replacements.

The application usage extends across paper, tissue, board and pulp producers, from recycled pulping to end of machine stock preparation. According to ABB, KPM KC7 is ideal for users of recycled raw material and pulp and paper mill teams that prefer to measure and control total consistency with microwave technology.
