Description

SE555 pH Sensor | Memosens | 120 mm | Ex | PWIS-free | Sterilizable | For aggressive media

Digital, sterilizable pH sensor providing high reliability and precision.

  • Also available as version with-out paint-wetting impairment substances (PWIS-free)
  • Gel electrolyte, pressurized
  • Ceramic junction
  • Silver ion trap
  • Integrated temperature detector
  • pH glass with high impedance for high-temperature applications, low alkali error
  • CIP/SIP-capable, safe sterilization with temperature monitoring
  • Perfect galvanic isolation thanks to Memosens technology
  • No influence of humidity in the connector
  • Precalibration in the lab
  • Digital data transfer
  • Integrated sensor diagnostics

The SE555 digital pH sensor comes with a special pH glass with high impedance for high-temperature applications and a low alkali error. The sensor is CIP- and SIP-capable. The silver ion trap prevents silver sulfide precipitation and junction fouling in media containing sulfides.

This makes the sensor ideal for routine applications in food processing and biotechnology. Additionally the Memosens technology offers all well known advantages concerning operation and sensor diagnostics.

Applications
Fermentation, food and beverages, aggressive media, extreme pH values

Used in Process or Applications

Cooling Water Systems
Measurement of pH value, redox potential, and conductivity in cooling water, which has to be continuously treated with acid and biocides.
Monitoring Brewing Processes
The taste and quality of beer are highly dependent on the quality of the water used for brewing it. It is determined by pH and conductivity measurements.
Monitoring Sugar Production
Sugar production places extreme requirements on pH sensors. As early as the beet washing phase, it is important to monitor the pH value since the lime is metered on the basis of the pH measurement.
Cooling Tower Monitoring
In a wide range of industrial sectors, cooling towers are used to dissipate process heat from cooling circuits. Mineral deposits and corrosion reduce their efficiency and lead to premature wear on plant parts.
Quality Control for Raw Milk Delivery
High quality requirements are placed on raw milk, and online monitoring of truck unloading procedure at the dairy prevents inferior quality (sour milk) from spoiling the entire stock of the storage tank.
