SC25V 12mm with Built-in Temperature and External Liquid Earth

Yokogawa is continuously improving our pH sensing portfolio and designing new sensors that integrate the latest improvements in the industry. The SC25V is the latest addition to the family, and Yokogawa's first combination pH sensor in a 12 mm design that 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.

  • External titanium Liquid Earth
  • Pt1000 integration in pH compartment giving highly accurate temperature compensation
  • ATEX certified : ATEX II1G Ex ia IIC T3...T6 Ga
  • 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 10 μS/cm
  • Variopin connector
  • SC25V-ALP25 for chemically harsh applications and high temperatures
  • SC25V-AGP25 for all General Purpose applications

Genel Bakış:

After extraction from sugar cane or sugar beets, juice must be purified to remove the many other organics and minerals that accompany it.
 The processing to accomplish this is heavily dependent on reliable pH measurement and control as illustrated.

Genel Bakış:

In stable dispersion of fine particles is the pre-requisite for the selective flocculation technique involving separation of ultra-fine valuable particles from the gangue. Among mineral processing techniques selective flocculation technique is known to have outstanding potential of capturing the particles of particular mineral in slurry of mixed mineral system by selective adsorption of water soluble polymers known as flocculants.

Genel Bakış:

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
Genel Bakış:

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.
