SC25F Digital SMART SENCOM™ pH 12 mm Sensor with Build-in Temperature and External Liquid Earth

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)
摘要:

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

摘要:

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.

摘要:

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.

摘要:

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.
