Key Features

  • Robust Process Design:​ The PES sensor body​ and graphite electrodes offer high chemical and thermal stability, suitable for aggressive media and temperatures up to 135°C.

  • Integrated Temperature Compensation:​ Built-in Pt100 sensor​ ensures accurate conductivity readings across the full operating range without requiring an external temperature probe.

  • Hazardous Area Compliance:​ Certified for use in ATEX Zone 1​ (and typically FM/IECEx) explosive atmospheres, making it ideal for chemical and petrochemical plants.

  • Plug-and-Play Connector:​ The 4-pin DIN connector​ (Pg9) allows for quick sensor replacement and easy connection to compatible transmitters like the Liquisys series.

Applications

  • Industrial Water Treatment:​ Conductivity monitoring in demineralization, reverse osmosis (RO), and cooling water systems.

  • Chemical Process:​ Concentration measurement of acids, alkalis, and process solutions in mixing and dosing applications.

  • Phase Separation:​ Interface detection (e.g., product/water) in pipelines and tanks based on conductivity differences.

  • Potable & Wastewater:​ General water quality monitoring in municipal and industrial effluent streams.
