The SC25F is Yokogawa's first 12mm combination design digital SMARTpH sensor. It includes an integral temperature element and a Liquid earth electrode. This design provides a large electrolyte volume giving the sensor longer life than most comparable pH electrodes.

  • Solid Titanium LE electrode for stable measurements
  • Integral Pt1000 element for enhanced pH accuracy
  • Versatile in-line, immersion or off-line installation
  • CIP and Steam cleaning possible
  • large internal KCL volume giving the sensor a longer life time
  • low conductivity applications possible from 10µS
  • SC25F-ALP25 for chemically harsh applications and high temperature
  • SC25F-AGP25 for all General Purpose applications
  • Easy setup by sensor specific characteristics stored in the sensor itself
  • Simple maintenance by comprehensive design
  • CE, ATEX, CSA and FM Approval. However *Can only be used General Purpose at this time, because FLXA21 SENCOM™ module and SPS24 Interface box are pending ICECx, ATEX, FM and CSA approval*

WU11 Connection Cable

The WU11 interconnection cable is specified for reliable transfer of digital signals between the SENCOM™ sensors and Yokogawa FLXA™ analyzer. It is espically designed to be installed in a heavy industrial environment. The cable is water proof, IP67, allowing it to be submerged as a whole. The cable has a wide temperature operation range which is sufficient for most of the applications. The materials used for the cable are flame retardant to resist the spread of fire.

  • Double shielding to protect connected devices for interference from high voltages and currents
  • Available in four different lengths. Long cable runs up to 100 m (328 ft) are possible
  • Easy connection to a SENCOM pH Sensor by one 5- pins molded connector, and to the analyzer by 5 wired pins
  • Flame retardant recognized by UL (fileno. E124763) and CSA (fileno. LL105324)
  • IP67
  • Operating temperature from - 40ºC up to + 85°C (-40ºF up to +185°F)
Overview:

Wet scrubbers are used in utilities, paper mills, and chemical plants to remove sulfur dioxide (SO2) and other pollutants from gas streams. Undesirable pollutants are removed by contacting the gases with an aqueous solution or slurry containing a sorbent. The most common sorbents are lime, Ca(OH)2, and limestone, CaCO3

Application Note
Overview:

For control of batch neutralization, a pH measurement coupled with a timer-controlled chemical feed scheme provides very satisfactory results.

This system can be adapted for either acid waste or alkaline waste neutralization.

Overview:

In flue gas desulfurization systems that use magnesium hydroxide (Mg(OH)2) slurry, the consumption of the desulfurization agent (Mg(OH)2) is controlled by using online pH analyzers. A great concern in the pH measurement is heavy staining of the pH electrodes by the Mg(OH)2 slurry. To ensure accurate measurement, frequent cleaning of the electrodes with an acid is required, adding to both maintenance workload and cost.

Industry:Chemical, Power

Application Note
Overview:

The lifetime of a pH sensor has a significant impact on the overall annual costs of a pH measuring loop. Optimizing four key factors will decrease these costs and optimize process control and overall plant efficiency.

    Overview:

    Are Pure water, Ultrapure water, UPW, or Water for Injection (WFI) important in your process? Would a better understanding of current water treatment equipment technology be useful? Would learning to better identify sources for potential process problem be helpful?

    Pure water, Ultrapure water, UPW, Water for Injection (WFI), high-purity water and deionized (DI) are all terms describing basically the same property. They refer to water which has been purified to the highest standards by removing all contaminants such as, organic and inorganic compounds; dissolved and particulate matter; volatile and non-volatile, reactive and inert; hydrophilic and hydrophobic; and dissolved gases. Pure water or conditioned water is used in a variety of processes across various industries; Power Generation, Pharma/Biotech, Semiconductor, and Drinking water are just a few examples. Please join us for a free 45 min webinar with 15 min Q&A section. As our presenter David H. Paul, Inc (DHP), gives an overview of high purity water treatment. What you will learn:

    • Understanding the purpose for each piece of equipment in a high purity treatment process flow
    • Basic overview of Reverse Osmosis Processes
    • Better understanding of when to "raise an alarm" when performance issues arise

    Information about the presenter: Since 1988, David H. Paul, Inc (DHP) has been the world's leader in reverse osmosis and high purity water treatment training. DHP has trained over 18,000 water treatment professionals worldwide.

    Overview:

    Proper pretreatment is critical for minimizing problems and reducing the need for chemical cleaning. This webinar will teach you the most common pretreatment technologies and why it is important to monitor and maintain them. Join us to learn:

    • Why pretreatment is important
    • How pretreatment protects your RO units from scaling, fouling and chemical attacks
    • What to monitor and why
    Overview:

    Basic pH/ORP Theory and gain an understanding of:

    • How pH and ORP measurement works
    • The differences in measuring electrodes and reference electrodes
    • The difference between ORP and pH compensated ORP

    How to choose the right reference and measuring electrode for your application, which includes:

    • The differences and benefits between all-in-one vs. individual electrodes
    • The benefits of SMART sensors
    • The difference between traditional and differential pH maintenance
    • Best practices for cleaning and calibrating
    • The benefits of sensor diagnostics and how to interpret the information
    Overview:

    Each of the previous webinars covered the basics and the monitoring requirements for a high purity water treatment system that included a Reverse Osmosis (RO) treatment step. In this final webinar, we cover the problems that poor RO unit performance can produce in downstream process steps and in the end use water. The webinar series started with topics concerning raw water contaminants and will end with following contaminants through the RO membrane and into downstream treatment steps including Electrodeionization (EDI), mixed-bed ion exchange, 185 nm and 254 nm UV, ozone and more. Join us and learn:

    • What and why certain measurement parameters should be monitored
    • When to "raise the alarm" when issues arise
    Overview:

    A common use for RO is for purifying water, removing salts and other impurities to improve the color, taste and other properties. It is regularly used for commercial and residential water filtration and is also one of the methods used for desalinization of seawater. RO systems are capable of rejecting bacteria, salts, sugars, proteins, particles, dyes, and other constituents which have a molecular weight of greater than 150-250 Daltons. RO systems are designed for automatic operation and require routine preventative and corrective maintenance. Common problems include membrane fouling and the use of improper flow rates. The result is reduced throughput capacity and shortened runs. What you will learn:

    • Overview of Reverse Osmosis Processes
    • Understanding of RO technology
    • Understanding the importance of RO operation and maintenance
