Yokogawa 21CFR part 11 Paperless Recorder Data Acquisition System
IPP have successfully installed the Yokogawa DXAdvanced R4 Paperless Recorder Data Acquisition system in large numbers throughout Ireland in heavily regulated Pharmaceutical and Medical Device companies, audited by both the FDA and Irish Medicines Board (IMB). The Background Irish Power and Process (IPP) is a leading supplier of validated Environmental Monitoring Systems (EMS), an independent back up to site Building Management Systems (BMS) systems in the Pharmaceutical, Medical Device and Laboratory industries. BMS Systems play a vital role in the running of a manufacturing process where the monitoring and control of atmospheric changes is crucial to consistency of production, sterility of end product and comfort of operators in the working environment. The validation of a BMS system is both a costly and timely exercise which many companies would rather avoid. The solution is the installation of an independent system that is easily validated and provides auditable records with full traceability of operation critical variables.

CONDUCTIVITY CALIBRATION WITH AN INSACAL MASTER METER
Why calibrate conductivity?
To be able to get a well documented and traceable means of calibrating your conductivity equipment to the standards required by USP (United States Pharmacopeia) or EP (European Pharmacopoeia). With an INSACAL™ master meter you get a very flexible calibration tool. You can calibrate by closed loop procedures or in an open beaker. This allows you to choose whether your cell is calibrated on-site in-situ or not. If customers use a ”Master Meter” these need to be calibrated. Issues that need to be defined are: • Accuracy and definitions • When to do electrical calibration • When to do temperature calibration • When to use comparative calibration • When to use a standard solution to determine the cell constant • Measuring ability |
Conductivity Master Meter with accredited calibration
With an INSACAL master meter you get a very flexible calibration tool. You can calibrate by closed loop procedures or in an open beaker. This allows you to choose whether your cell is calibrated on-site, in-situ or not. Why use an accredited calibration laboratory?
The ISO17025 standard is used for evaluating laboratories, and this standard has the criteria’s relevant to a laboratory to perform precise and accurate test and calibrations • Technical competency of the personnel • Validity and appropriateness of the procedures and methods • Traceability of calibrations to national standards • Appropriate application of measurement uncertainty • Suitability, calibration and maintenance of reference equipment and the laboratory • QA of inspection and calibration data • Continued compliance are ensured by audit from the national authorities • Suitability, calibration and maintenance of reference equipment, laboratory environment, Quality assurance of calibration data.

CIP PROCESS IMPROVEMENT
Process Overview
CIP systems depend on the process differentiations of Pharmaceutical, Chemical and Food & Beverage. In addition, the cleaning solutions and chemicals are different. The chemicals that are generally used are hypochlorous acid, caustic soda, and nitrous acid. In a cleaning solution recovery system, the process lines and piping are cleaned with an initial cleaning solution. After that, the cleaning solution is cleaned with fresh water. The cleaning solution is recovered at that point, but since it gradually becomes diluted with fresh water, recovery is discontinued and the solution is discharged through a drainage line when the concentration of the cleaning solution drops below the standard value. The cleaning with different solutions or fresh water, the recovery of the cleaning solution, and the discharge of waste solution are repeatedly carried out. In addition, sterilization with steam or cleaning with distilled water or de-ionized water is performed as a final step in some cases. |
Measuring conductivity correctly in
clean-in-place (cip) system Yokogawa's FLXA 21 Inductive Conductivity Transmitter has earned a reputation in the recovery of cleaning solutions because it can take measurements with good boundary surface precision over a wide range. This reduces operating costs and optimises cleaning and sterilising. Industry: Pharmaceutical, Chemical, Food & Beverage Product:
Inductive conductivity analysers In the manufacturing process of Pharmaceutical, Chemical and Food & Beverage industries, the cleaning and sterilization of tanks and piping are done with various cleaning solutions, fresh or hot water and steam after manufacturing products. Clean-In-Place (CIP) is the system designed for automatic cleaning and disinfecting. The recovery of cleaning solutions contributes significantly to reduce chemical costs and wastewater processing costs. Yokogawa FLXA21 inductive conductivity transmitter has earned a reputation in the recovery of cleaning solutions because it can take measurements with good boundary surface precision over a wide range.

ISC450 - PROGRAMMING PERCENT CONCENTRATION PREPROGRAMMED CURVES
|
Set Up SC450 to Read Temperature
There are two choices for programming the ISC450 for Percent Concentration measurement. The simplest, is to select one of the "built-in" tables already provided in the ISC40. However, if none of these tables meet the application requirements, then the second option of creating your own table specific to your needs can be used.

By using the Yokogawa UT35A, it provides a cost effective solution for pH applications.
Solution
2-wire pH transmitters like the Yokogawa Flexa cannot power relays, which would be used to start the wash system, due to the requirements of hazardous areas, as such supporting a wash system is not possible. Using the UT35A Controller product with in built ladder functionality allows a wash system to be created outside the pH transmitter, along with the added benefit of providing pH control as well. The UT35A can be mounted in a safe area and using barriers the wash system can be operated. The ladder function within the UT35A controller allows the interval timer, wash cycle timer and recovery timer to be utilized and for the 4-20mA pH signal to be held during the wash and recovery periods. By holding the value during the wash cycle and the recovery period, interruption to the process is avoided. |
pH Control and Wash System for 2 - Wire Transmitter Using Controller with PLC Function
pH wash systems are a requirement for many industries where electrode fouling is common place. Large amounts of deposits form over a period of time preventing the sensors performing correctly. This results in measurement loss and repeated expensive electrode replacement. It is difficult to apply wash systems to 2 wire transmitters due to hazardous area restrictions therefore incorporating the wash function within a control device outside the hazardous area provides an cost effective solution. Overview
pH wash systems are a requirement for many industries where electrode fouling is common place. Large amounts of deposits form over a period of time preventing the sensors performing correctly. This results in measurement loss and repeated expensive electrode replacement. It is difficult to apply wash systems to 2 wire transmitters due to hazardous area restrictions therefore incorporating the wash function within a control device outside the hazardous area provides a cost effective solution. Application Outline A perennial issue encountered in process pH measurements is the coating of the electrode surface by a component of the process fluid. In order to function correctly a pH electrode needs to make a good contact to the liquid it is measuring. Any deposit forming on the electrode forms a barrier between the electrode sensing surface and the fluid being measured, depending on the type and degree of deposit it will at least slow the response and, in time, prevent the electrode functioning at all. The ramifications of this for users are significant:- • Slow measurement response • Inaccurate measurement results • Increased maintenance costs • Increased consumable costs • Increased incidence of unavailability • No confidence in the measured result
