Description

SE680 Digital Toroidal Conductivity Sensor | Clamp 2" | Ex | FDA-approved PEEK | Measuring range 0 … 2000 mS/cm

High-precision sensor made of FDA-approved PEEK with an extremely large measuring range. Steam-sterilizable.

High-precision sensor made of FDA-approved PEEK with an extremely large measuring range. Steam-sterilizable.

  • Compact design
  • Competitively priced
  • Large measuring range
  • Quick-reacting temperature detector
  • Digital data transfer
  • Completely closed surface
  • Virgin PEEK, FDA type
  • Varivent with EHEDG

The joint- and gap-free, sealless design and stain-resistant surface made of Virgin PEEK make the SE680 a heavy-duty sensor. The inductive technology is not influenced by polarization and does not have any sensor surfaces subject to corrosion.

Applications
Fresh water technology, dairy products, breweries, soft drink manufacturing, electroplating, air-conditioning, CIP monitoring in the beverage industry, pharmaceutical applications, cooling tower monitoring, on-site wastewater treatment plants, monitoring concentrations of salt solutions, alkalis and acids, washers, and rinsing processes
