Non-contact optical measurement
With hundreds of installations worldwide, the KPM KB2 FiberOptic Sheet Break Detector is recognized as the best sheet break detector on the market. The non-contact sensor is placed above or under the web to be monitored. KPM KB2 is suitable for dirt, steam and high-temperature installations or where space is limited. The air-purged sensor head stays clean while monitoring for sheet breaks in the harshest environments.
Easy to set up
KPM KB2’s large display and logical user interface allows easy setup of the break detection by selecting the measurements that give the highest signal difference. Break and maintenance alarms are wired to the PLC or DCS.
Fast break detection
The KPM KB2’s digital signal processing technology measures all signals at a thousand times per second. KPM KB2 is immune to ambient light changes by measuring the backlight intensity. The break detection delay is a minimum of 15 ms. With digital filtration, users can select how many measurement cycles are used for break alarm.
RGB and infrared light measurement
KPM KB2 has RGB or infrared light sources to perform superiorly on all paper and board grades and applications, regardless of color. The RGB color measurement can handle all sheet, wire and felt colors providing reliable break detection. In addition to open-draw applications, the breaks can be detected against felt, wire, or even against a cylinder.
Electronics located outside harsh environment
KPM KB2 is very reliable even in a 100 percent humidity environment. While the sensor head is exposed to high temperatures, the electronics unit is mounted outside the machine hood to convenient location using fiber optic cable.
High performance sampling for screened and unscreened applications
With high performance sampling for screened and unscreened applications, ABB offers the widest portfolio of cost-effective, durable and versatile sample valves for all applications. The KPM KS2 covers low consistency screened applications. KPM KS4 and KPM KS6 samplers handle unscreened extractions with a cutting piston.
Manual & pneumatic versions available
KPM KS2 is available in manual and pneumatic versions; KPM KS4 and KPM KS6 are pneumatically operated only. Saddle and threaded mounts are options for KPM KS2 and KPM KS4 samplers, while KPM KS6 is saddle mounted only
Safe and representative sampling
The KPM KS-line sampler heads penetrate the water layer inside the pipe, eliminating dewatering from the sampling process. KPM KS4 and KPM KS6 have stroke depth adjustment for sample flow, ensuring reliable operation with unscreened pulp.
Water flushing
A separate water connection allows cleaning of the sample valve after a collection. Flushing ensures a repeatable and representative sampling procedure.
Reduced maintenance costs
All KPM KS samplers have seal-less construction, allowing a maintenance-free operation.
Pneumatic operating valve
All pneumatic KPM KS samplers are equipped with an operation valve. An optional electric switch detects the pistons position.
Options
Electric position indicator for sampling pistons enables time stamping in the DCS.
Reliable, damage resistant transmitter
Retention control is important to papermakers due to the large influence it has on paper quality variability reduction. ABB’s ultimate solution for monitoring and control of paper or board machine retention is KPM KRA and KRT Retention Measurement
Benefits
- MD variation reduction in
- Basis weight
- Moisture content
- Ash content
- Web break reduction
- Faster grade changes and start-ups
- Optimization of retention chemicals
Retention Measurement System
ABB offers two options for paper and board machine retention monitoring and control: the KPM KRA sensor measures total consistency and ash consistency, while the KPM KRT sensor is for total consistency only. The measurement range for total consistency is 0-2.0 percent Cs and 0-1.0 percent for ash consistency.
Robust design and construction
The sensor is constructed of 316SS with an unbreakable stainless steel measurement cell, enabling the sensors to withstand harsh environments. The display unit and sensor have protection class of IP65 (Nema 4X) and do not need protective housing to withstand difficult conditions at the paper machine wet end.
Maintenance-free operations
Automatic flushing with water can be included to keep the sensors clean without maintenance. The optical sensor has a 3 mm gap between the lenses, which produces a self-cleaning effect due to the increased velocity. The white water sensor also has self-cleaning due to an automatic backflushing module.
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.
