ABB has released the KPM KC9 Optical Consistency Transmitter family, a new range of sensors that provide accurate measurement of total and/or ash consistency for better wet end measurement and control in pulp and paper processes.
The sensors are suitable for pulp, paper, board and tissue manufacturers using virgin or recycled raw materials, particularly those using ash fillers, where only optical sensors are effective to measure ash consistency.
Available as either inline or bypass sensors, the entire KPM KC9 Optical Consistency Transmitter family is best suited to measure the lowest consistency ranges. The sensors permit maintenance while processes are running, unlike other consistency sensors which require a shutdown and emptying of the process pipe.
The sensors work in tandem with ABB’s KPM KRA/KRT Retention Measurement System, used to monitor and control paper and board machine retention. Available in two options, the KRA unit measures whitewater total consistency as well as ash consistency. The KRT unit measures total consistency only.
The KPM KC9 inline consistency sensors are developed to measure single-component fibre consistency in liquids from 0-14 per cent.
The KPM KC9 bypass consistency sensors are developed to measure consistency in liquids from 0–5 per cent.
All the new models with updated electrical and software design are evolved from the KPM OC Optical Consistency Transmitters.
