Page 3: Introduction
Transmitter functions as well as the measuring principle are discussed, but the man- ual primarily describes the applications and the starting up of the CTXP 03/25 when it is connected to the BB2. Menu functions and technical data of the BB2 control box can be... -
Page 4: Unpacking The Ctxp Flow-Through Sensor
Damages If damages occurred during the shipment, immediately contact the UPS or truck line as well as your Cerlic representative. The shipment can be returned only after contact has been made with Cerlic. Packaging The original packaging is designed to protect the equipment and should be used for storage or if the goods must be returned. -
Page 5: Mounting Of Flow-Through Sensor
There are three possibilities to mount the CTXP sensors, NPT-couplings (standard delivery in the US), Butt weld end connection (standard delivery except for the US), or Hose connec- tion. - Page 6 • Installing the sample or bypass line in a vertical pipe will reduce the influence of en- trained air in the process liquid and the tendency for laminar flow. • In order to avoid the water film on pipe walls, the sample or by-pass pipe should ex- tend at least ¾”...

Page 7: Automatic Flushing
If the sensor is disconnected under process pressure this could cause serious injury or even death. Cerlic does not accept any responsibility for accidents caused when the sensor is disconnected while still under line pressure. - Page 8 The sensor housing may not be opend except by Cerlic service personel. Opening the sensor housing will void all warrenty. Page 8...

Page 9: Menu For Ctxp Sensor
Menu for CTXP sensor to select the sensor in the main display. Press ENTER for five seconds to access the menu for the selected sensor. Settings Name of the sensor (10 characters) shown in the main display. Calibration Curves ”A”-“D”, or “Ext”. Tells BB2 which one of the four calibration curves to use. -

SA and Cons repeated for samples 2 to 5 Info This menu is for Cerlic internal use, it may change without notice Linearized light signal, which are SA values in calibration chart Unit value in %, ppm, mg/l, or g/l after MS value has been converted to units due to sample values. -

Unit is selected in the sensors setting menu. Multiple Calibration curves The CTXP sensors have the possibility to define four independent calibration curves to han- dle different types and qualities of pulp. Each curve has up to five calibration points. All four curves have a common zero calibration point. -

This is not a fault, it just indicates the liquid in the sensor depolarizes less light than the liquid used as zero reference. Please contact Cerlic service if this is a problem for you. -
Page 13: Calibration Screen
Calibration screen The CTXP sensor information menu is the calibration curve screen. To change between the main menu and the calibration screen, press and ENTER simultaneously. Two point calibration Several point calibration BB2 uses at least a zero sample and one sample (two point’s calibration). Up to five samples may be used to create a calibration curve (multi point calibration). -

10000 mg/l it shall be changed to 10500. Using statistic method will increase the accuracy and reliability of the measurement as time passes while new cali- brations will start from scratch. An Excel sheet to help doing statistical adjustment of the calibration can be downloaded from http://www.cerlic.com Page 14... -
Page 15: Zero Calibration
Zero Calibration The sensor is zero calibrated at the factory, and does normally not need to be zero recali- brated. Before doing a zero calibration make sure that it is really needed. Make sure the win- dows are clean, and use clean de-aerated water to check the meter reading. Tap water is best de-aerated by leaving the water in an open bucket for at least two hours. - Page 16 Page 16...

Page 17: Calibration With Multiple Points
Calibration with one point is done in the following way: • Open the valve on the upstream side of the sensor completely. • Open the valve on the downstream side halfway. • Go to the CALIB menu and select “Take sample – #1”. •... -
Page 18: Scaling
That makes the CTX react very strongly to an addition of TiO 2 . The measuring prin- ciple of the CTXP makes it almost completely insensitive to variations of light intensity in a nominal measuring interval, and therefore the CTXP does not react as strongly to TiO 2 as the CTX. - Page 19 Groundwood pulp blocks out light to a very high degree. Therefore, the CTX does not react to the same degree to the chalk, which also blocks out light to a relatively high degree. The CTXP reacts to a lesser degree to chalk than to titanium dioxide, but more than if one com- pares with clay.

Page 22: Appendix 1. Sample Instructions - Manual Test
Appendix 1. Sample instructions - manual test The best place for the sample test tap is as close as possible to the sensor process connection. The flow during of the test should be in the range of 30 - 35 l/min or 8-10 gpm. Too much flow will make it more difficult to gather a sample due to high velocity or flow rate. -
