KPM KC9 Optical Consistency Transmitter

Widest consistency range
Optical consistency transmitters are typically the only choice for measuring total consistency range below 2 percent. ABB offers the latest design in optical consistency transmitters covering the widest consistency range for inline and bypass installations. The variety of sensors utilizing different measuring principles ensures that each application can be covered cost effectively without compromising measurement accuracy.
Robust design in AISI 316 steel & sapphire
KPM KC9 sensors are constructed of a stainless steel measurement cell and sapphire glass lenses to withstand the harsh process environments. The display unit and sensor have protection class of IP65 (Nema 4X).
KPM KC9 Inline Sensors
The KPM KC9 inline sensors can be installed directly to process pipe by using Sandvik NS40 process coupling. The sensor is available with optional retraction system, enabling sensor maintenance without interrupting the process. The inline consistency sensors are developed to measure single component fiber consistency in liquids from 0-14 percent.
KPM KC9 Bypass sensors
The bypass consistency sensors measure consistency in liquids from 0-5 percent. KPM KC9-25 and KPM KC9-50 are suitable for single component fiber consistency and KPM KC9-25 LC for very low consistency applications. KPM KC9-P is ideal for multicomponent stock total consistency measurement. KPM KC9-A includes additional ash consistency measurement.
Remote Display unit for operation
The sensors are pre-calibrated for quick and easy start up. After installation, one-point adjustment is performed against a laboratory test. The display unit has four selectable calibration models for applications with varying furnishes.
